Greenhouse seedlings, transplants are ready six to eight weeks early and you can grow Out-of-Season Treats in winter! Pest and disease free equals greater production! For institutions like hospitals, greenhouses are workhorses! A greenhouse is a most valuable part of a productive home garden. Seedlings are ready for earlier planting. Hospitals want the best food possible for the health of their patients, and can’t afford to be weather dependent.

As a home gardener in coastal SoCal areas you may question the need for a greenhouse. Though unheated, ours at our mile-from-the-beach community garden is well used! We often run out of space for everyone’s seedlings as we get closer to planting time or the weather warms! Even unheated, an enclosed space is heated by the sun during the day and doesn’t get so cold at night, no chilling winds or late freezes in there! Seedlings are protected from marauding pests, birds, walkabout creatures. Foothills and inland gardeners get more heat and more COLD! They really can use greenhouses to advantage.

Greenhouse Long CucumbersIn addition to starting preseason transplants, in a heated greenhouse you can grow out of season tomatoes, peppers, lettuces, cucumbers, beans, eggplant, zucchini, cantaloupe! Herbs, chard, raspberries and strawberries! And winter crops too if you just have too much snow outside!

Your greenhouse doesn’t need to be huge or showy. It just needs to do the job.

Super options!

Our land is flat, but yours might have slopes and you could choose to have an earth shelter space complete with indoor shower! See also Heating Greenhouses Without Electricity!

Greenhouses come in a vast variety of shapes from squares to pillowdomes! Buy a premade kit or design and build it yourself entirely to your specs.
You can have a 2′ wide up against the chimney mini to a palatial entire rooftop greenhouse with an elegant view!
You may have a built in the ground greenhouse cousin, a cold frame, or an indoor kitchen window box.

Materials vary from hoop frames to the fanciest filigree and glass, cob or strawbale! They can be spanking new, made of have-arounds, or be recycled from demolition sites! Covering materials can be poly films, panels, glass and glazing. There are so many new products, techniques, new research, all the time, and each person’s needs are so different, it is wise to check these things out for yourself. Talk with several ‘experts’ on each topic. Read up online. Compare. See what you really want. See what will do the best job for your needs.

If you have space for a larger greenhouse, consider gardening some of your crops in it! Hoop houses, or high tunnel farming is a recent invention. They are certainly the larger version of traditional row covers! There are huge commercial installations. Yet home made hoop houses can be no bigger than 8X8, so easy to put up a child can do it!

  • Season extension is the #1 advantage. 30 days on the front end and 30 days on the back end of the growing season is equivalent to moving your farming operation 400 miles to the south!
  • Yields increase when your plants are protected from excessive rain and wind. When a more ideal growing temperature is maintained, a reduction in temperature-related stress, fruit set, fruit size increases.
  • There is no bolting, so no loss of your plant’s production.
  • Because temperatures are maintained, you can plant when you want to, not have to wait until conditions are favorable.
  • Soil conditions are more controlled, less moist, less to no fungi – wilts, blights.
  • No pests, no pesticides! No birds, small mammals.
  • Plus, they are movable!

Greenhouse Energy Efficient Attached Lean ToEnergy efficient attached greenhouses make a lot of sense. The home, and these bricks, help heat the greenhouse for free! Some attached greenhouses are beautiful walkin sunrooms, garden rooms, conservatories!

If you decide to build a greenhouse yourself, first check on local ordinances and with your neighbors. Place it conveniently, near electrical and water access if possible. Choose a location with a winter angle for maximum light, as much sun as possible. Use trees for windbreaks if necessary.

Know your prevailing wind direction, be sure it is well anchored. Use concrete blocks with eye hook attachments, sink posts or anchoring stakes, or use sand, not rocks, on the windward base cover.

Your roof choice tells us what kind of weather you have! Steep slopes and insulated lower areas tell us you are in high cold country with snow and need to decrease your heating costs. Medium slopes with rounded shoulders are good in windy and rainy areas. An extended slope on one side that faces the sun tells us you may get a lot of shade from trees on one side.

Doors make a difference. If you are in a windy area, you might choose sliding doors that can be secured and weather stripped versus velcroed flaps, zippers or swing out doors that blow away or animals could get through.

Ventilation is key! Hot days are hot! In two shakes a greenhouse can to get up to 110 degrees! Doors and windows can be the vents if intruders are not an issue, otherwise, ceiling vents are best. Solar devices can be set to open when temps hit a high level. Fans may be needed.

Greenhouse sloped for lots more Solar energy!Electrical! Get advice from a greenhouse experienced professional because of the extreme conditions: heat, wet, cold. Make sure that person knows local codes
Consider solar lights, vent openers, fans or simply long sloped sides to have lots more solar energy as in the image!
Growlights? Yes!
Night light to see by
Computer monitor

Irrigation tips! Put your timer OUTSIDE! Make & see your adjustments without getting wet! Mini drop down sprayers or foggers at varying adjustable heights along an overhead line are fabulous! Consider recycling your water – is it legal to use grey water where you live? Collect rainwater.

A word about Damping Off. Damping off is a common problem with seedlings started in containers, indoors or in greenhouses. Per Planet Natural: ‘Several fungi can cause decay of seeds and seedlings including species of rhizoctonia, fusarium and phytophthora. However, species of the soil fungus pythium are most often the culprit. Damping off typically occurs when old seed is planted in cold, wet soil and is further increased’ by poor soil drainage.

Disease Cinnamon Damping Off PreventionThe super simplest prevention is Cinnamon! Just sprinkle it on the soil! Sprinkle on plant injuries and they will heal. It is a rooting hormone. Mildew, mold, fungal diseases? Mix 4 tablespoons cinnamon in a half gallon warm water, shake it vigorously, steep overnight. Strain through a sieve or coffee filter and put it in a spray bottle. Add ¼ teaspoon liquid dish soap as a surfactant, lightly spritz your plants, undersides and tops of leaves! (In Santa Barbara area buy it in big containers at Smart & Final.) Also, it repels ants!

Pathway and Flooring best for your plants and feet! Have a sturdy pathway that stands up to wheelbarrow use. A non muddy pathway saves your greenhouse floor. A raised flooring keeps you from having a muddy mess. Drainage is necessary so there is no rot or mold. Heated flooring is the best. There are great options, more and less expensive! Concrete, rubber matting saves your feet. Dirt, my last choice, and/or pavers. Decomposed granite, pea gravel, raised wooden slats, pallets, straw, chips – use weed mat underneath! Use pest protection wire under weed mat and soft flooring choices. No gophers, no mice, squirrels, bunnies or snakes, thank you.

Greenhouse Shelving FanShelves and Worktable

Make your work table a good working height for you
Shelving needs to be safe and well supported
Construct your shelves wire covered like the top shelves in the image, or like the lower shelves, out of spaced boards so water drains, the boards dry, there is no mildew or mold.
Enough space between boards makes it easy to clean
Or use open wire metal shelving that allows drainage and dries
If there is lower shelving, slant it down from back to front

  • so you can see what is in the back
  • It is easier to get items in back out – keep heavier items to front
  • No water clings to it – stays dry, no rot or mold

OR some say don’t have bottom shelves so there is no nesting space for mice or chipmunks – they WILL eat your plants! You want to be able to SEE the ground! Depends on how critter secure your house is.

Rather than just the greenhouse, consider a 4 part working complex! A storage shed, the greenhouse, a covered work area and hardening off area.

Tool & Gear Storage could hold your tools and supplies!

Wheelbarrow, all tools – shovel, rake, pitchfork, spade fork
Small tools – trowel, clippers, sprayers
Bags of compost, potting mixes etc
Plug trays, biodegradable containers, labels
Gloves, apron, work boots, jacket
Greenhouse gear & replacement materials

Greenhouse Support Supplies!

Heating gear – heaters, heating mats
Cooling systems – fans
Irrigation, misting items
Lighting – grow light, night light
Thermostat, humidity (no mold), temperature   devices, CO2 generators
Secure, safe-for-children and pets, dry storage containers

Your Workspace needs a sun shade top and wind screen side. It would be a good place for your composter, worm bin and might be a good place for your rain collector barrels

Care and Maintenance

Seasonal checks, reset watering needs, replace brittle coverings
Routine cleaning inside and out
Equipment
Sterilize propagation area
Ventilation – Heat, condensation. Insulation – Frost
Deal with pests and diseases immediately!

Greenhouse Reused Doors and WindowsGreenhouses made of reused doors and windows are much more green than recycling!

Sustainable Greenhouses are often compost or solar heated!
They have heated benches and floor because root zone temperatures are more critical to plant growth than leaf temperatures. By maintaining an optimum root zone temperature, greenhouse air temperatures can be lowered 15° F!
LED’s balance good light, cooler temps
Hydroponics (preferably aeroponics) remove excess heat and water vapor
CO2 is recycled by breaking down old plant debris in a digester
Soluble components of the plant debris can be incorporated back into the nutrient solutions.

Rooftop greenhouse with a view of the city! Germany Fraunhofer UMSICHT

Fresh City Tomatoes, Any Time! On his way home from the office, the computer scientist harvests tomatoes from his company‘s rooftop greenhouse. No food miles! Why not produce lettuce, beans and tomatoes where most of the consumers are to be found: in the city? The flat roofs of many buildings are well-suited for growing vegetables. Rooftop greenhouses can also make use of a building‘s waste heat and cleaned waste water. Solar modules can do the rest. This uptown rooftop greenhouse urban garden is in Germany. Image courtesy of Fraunhofer UMSICHT.

Greenhouse Conferences! Tradeshows, sustainable, educational. Local, international! If you love greenhouses, might want to do urban agriculture business, just want to get involved, check these out online. There are different sponsors, different locations each year!

Whatever your special connection is, in SoCal, before our winter rains and cooler weather, late summer, early fall are perfect for getting your very own fine greenhouse up and running! If you miss that window, very early in the new year is good so you can start seedlings for early March plantings!

You might decide to sleep in it the first night!


The Green Bean Connection started as correspondence for the Santa Barbara CA USA Pilgrim Terrace Community Garden. All three of Santa Barbara’s community gardens are very coastal. During late spring/summer we are often in a fog belt/marine layer most years, locally referred to as the May grays, June glooms and August fogusts. Keep that in mind compared to the microclimate niche where your veggie garden is. Bless you for being such a wonderful Earth Steward!

Summer Heat Lovers Harvest Basket by Komali Nunna

Komali Nunna says ‘One of my greatest pleasures of summer is that I get to harvest from the kitchen garden and create meals around my harvest. I love to grow as many exotic vegetables as possible for my table, including red okra, green eggplant and an Indian cucumber called dosa kaya.’ …at Entertaining From an Ethnic Indian Kitchen

Recently night air temps have been steadily in the early 50s. Soil temps in the sun are now just 60. 60 to 65 are what we are looking for. Peppers especially need warmer temps, nighttime temps above 55°F and soil temps above 65°F. If planted too soon, sometimes they miss their natural sequence of production, and never produce. Best Planting Temps Per Veggie!

APRIL through June Planting Timing

APRIL! is true heat lovers time! Start MORE seedlings indoors NOW for successive June plantings. Sow seeds. If seeds and tending seedlings aren’t for you, get transplants and pop them in the ground per their right times! April 1 or as close to it as you can, start your Jicama seeds! Winter squash for sure. It needs time to grow big and harden for winter storage. MAY for cantaloupe, peppers, pumpkins and squash! Wait until the soil has warmed to 70°F before planting squash and melons. Many wait until May, some even June, to plant tomatoes to avoid soil fungi. Some gardeners wait until JUNE to plant okra. Okra really likes heat and grows quickly when happy. Choose faster maturing varieties for coastal SoCal. Long beans need warm temps to start from seeds. If YOU anticipate a HOT summer, plant a tad earlier, but be prepared to deal with it if summer is overcast as often is the case after all.

It’s heat lovers time! Eggplant, limas, okra and peppers, pumpkins! Transplant early-maturing varieties of beans, cucumbers, eggplant, melons, peppers, squash, and tomatoes. Sow and/or transplant asparagus, beets, carrots, celery, chard, corn, herbs, kale, kohlrabi, leeks, heat-tolerant leaf lettuce, okra, summer-maturing onions, parsley, peanuts, the last peas (choose a heat-tolerant variety such as Wando), white potatoes with zucchini, radishes (with cukes to repel cuke beetles, and with eggplant to repel flea beetles), rhubarb, and spinach.

Choose heat and drought tolerant varieties when you can. For example, why wait when it gets HOT and your tomato stops setting fruit?! Get heat tolerant varieties! Check out this nifty page of options at Bonnie Plants! Tomatoes are the Fireworks of Your Summer Garden!

Tomatoes! Heirlooms are particularly susceptible to the wilts, Fusarium and Verticillium. Instead, get varieties that have VFN or VF on the tag at the nursery. The V is for Verticillium, the F Fusarium wilt, N nematodes. Ace, Early Girl, Champion, Celebrity, are some that are wilt resistant/tolerant. In Santa Barbara area continued drought conditions, consider getting only indeterminates. In the Mother Earth News tomato survey, they found gardeners chose heirlooms over hybrids if their soil is wilt/blight free. Otherwise, the longer the gardener has gardened, they more they chose wilt resistant toms if their soil has fungi. La Sumida has the largest tomato selection in the Santa Barbara area! See Special Planting and growing tips for your Tomatoes and Cucumbers! 

Time for heat-resistant, bolt-resistant lettuces of all kinds! Sierra, Nevada, Jericho, Black Seeded Simpson are some. Tips for super Successful Transplanting!

Strengthen your garden! Remember, plan your Companions! Keep the biodiversity rolling! Plant pest deterring plants first so they will be up and working when you put in your or seeds or transplants!

  • Basil is great with tomatoes, and a pack of culinary dandelions!
  • Beans, Cukes, Dill, Radish Combo! Cukes and Beans are great on the trellis, one high, one low. Dill to go with pickling cukes. Radishes to deter Cucumber beetles.
  • Potatoes with Zucchini to repel squash bugs.
  • Radish with eggplant, cukes & zukes as trap plants for flea beetles and to repel cucumber beetles.
  • Carrots love being with cilantro and chamomile, and chamomile improves the flavor of any neighboring herb!
  • Calendula traps aphids, whiteflies, and thrips!
  • Marigolds are brilliant and called the workhorse of pest deterrents!

Keep ’em coming! If you have already done some planting, mid to late April, schedule to pop in another round! Poke in some bean seeds where your very last peas are finishing, add cucumber seeds between the beans, plus dill at each end of the trellis to be there when you pickle your cukes! Plant more radishes to deter the Cucumber beetles, repel flea beetles. Fill in spots that could use a helper companion plant like calendula or chamomile. Succession planting makes such good sense. Put your seeds and transplants in at the same time. Seedlings will come along 6 to 8 weeks behind your transplants so you have a steady supply of yummy veggies! But, again, if tending seedlings isn’t your cup of tea, just leave space and put in more transplants in 6 to 8 weeks after your first planting.

It is perfect to put in fast growers like lettuce, beets, turnips, arugula, to hold space until you are ready to plant bigger plants. When it’s time for the bigger ones, clear a space/harvest, pop in your seeds or transplants and let them grow up among the littles. As the bigger plants start to shade out the littles, remove lower leaves so the littles get light too! If you anticipate a HOT summer, plant littles on the morning light side of larger plants.

Put in borders of slow but low growers like carrots, mini cabbages, in more permanent placements, like on what will become the morning side of taller backdrop plants like peppers and eggplant.

Natural Disease & Pest Prevention!

  1. Be wise and pick the right plant varieties for your temps and conditions! Get heat tolerant, bolt resistant, drought tolerant, disease tolerant/resistant. If you are just starting, just start! You will learn as you go. Our climate is changing, so we are all adjusting and plants will be being hybridized, and hybridize naturally, for new climates. We can get varieties from other areas that are already used to conditions we will be having. Together we will do this.
  2. Think biodiversity! Plant companion plants that repel pests, enhance each other’s growth so they are strong and pest and disease resistant. Mix it up! Less planting in rows. Split up groups so pests won’t go from one plant to the next, and the next. Allow enough room for air space between, no leaves of mature plants touching each other. That breaks up micro pest and disease habitats.
  3. Make top notch soil! Make compost. Grow worms for castings. In planting areas add tasty properly aged manure mixes. Add non-fat powdered milk for immediate immune system support at planting time; put in a finely ground bone meal for later uptake when your plant gets to flowering time. Sprinkle mycorrhizae fungi directly on transplant roots, all but Brassicas, at planting time to increase their uptake of nutrients and water.
  4. Immediately drench your transplants, foliar feed, with a non-fat powdered milk, baking soda, aspirin, soap mix to jazz up their immune systems. Specially give your peppers an Epsom salt and soap mix bath for a taste of sulfur. More details and all the recipes.
  5. Maintenance! Keep your plants strong while they are working hard! Be ready to do a little cultivating composts and manures in during the season (called sidedressing), or adding fish/kelp emulsion mixes if you don’t have predator pests like skunks! Keep your plants watered and vibrant, but not so much as to make their leaves soft and inviting to munching insect pests like aphids. Trap gophers immediately if you are able.
  6. Harvest promptly. Insects and diseases know when plants are softening and losing strength as they age. Insects are nature’s cleaner uppers, and they and diseases are hungry! If leaves are yellowing or not looking up to par, remove them. Whiteflies are attracted to yellow.
  7. Prevention A frustrating typical spring disease is Powdery mildew. It’s common on late peas, Curly Leaf kales, broccoli. Plant leaving plenty of space for air circulation. Apply your baking soda mix. Drench under and upper sides of the foliage of young plants to get them off to a great start! Do this the same or next day if transplanting. A super combo is 1 regular Aspirin dissolved, a 1/4 cup nonfat powdered milk, heaping tablespoon of baking soda, a half teaspoon liquid dish soap per gallon/watering can. Reapply every 10 days or so, and after significant rains. Not only is prevention so much better than after mildew has set in, but this mix stimulates your plant’s growth! See Aspirin Solution.

Water Wise Practices!

  • Please always be building compost. Compost increases your soil’s water holding capacity.
  • This California drought year consider planting IN furrows, where the moisture settles. Plant crosswise to the Sun’s arc so the plants’ root areas will be slightly shaded by the depth of the furrow in early AM and late afternoon.
  • Make mounds with basins on top. Rather than losing water to evaporation from overhead watering, put the water right where it will do the most good and nowhere else. Make the mound to the dripline of your plant so small surface feeder roots get moisture for food uptake. For larger leaved plants, put a stake in the center of the basin so you know where to water. With a long watering wand you can water under the leaves rather than on them ~ unless they need a bath.
  • And, PLEASE MULCH. It keeps your soil cooler, moister, less water needed. And it stops light germinating weed seeds! Plant littles like lettuces, a bit more densely, under larger plants to make living mulch.
  • Sprinkle and pat on Mycorrhiza fungi right on the roots of your transplants when you put them in the ground. It increases uptake of nutrients, water, and phosphorus that helps roots and flowers grow and develop. Ask for it bulk at Island Seed & Feed in Goleta.
  • Dust Mulching, cultivation, weeding, is perfect to break up exposed soil surface. That keeps the water from wicking to the surface and evaporating. If you use a hula hoe you do two things at once! Just a half to one inch depth cuts off weed sprouts that use water. Indeed, it turns the soil a tad, all that’s needed. More weeds will follow, but it’s quick and easy to repeat the process. Two, three times, a few days apart, and there will be few weeds after that for awhile. Get ’em while they are small and easy to do. Smart gardening.

Put in last minute amendments, soil preps for May plantings of Cantaloupe, okra, tomatoes. About Manures

Keep COMPOSTING! Soil building is the single-most important thing you can do for your garden. Compost keeps your soil aerated, has great water holding capacity, feeds just perfectly! And if you made it, you know what’s in it! Make it HOT, Cold, or In place!  Dry is dead, so be sure it is always slightly moist. Giving back to Mama Earth is nature’s natural way! And, like Will Allen says ….there is something very Spiritual about touching the soil, that’s where life begins.

Plant Bee Food, Herbs and Flowers! Sow or transplant basil, borage, chervil, chamomile, chives, cilantro, comfrey, dill, fennel, lavender, marjoram, mint, oregano, rosemary, sage, savory, tarragon, and thyme. Be mindful where you plant them… Mediterranean herbs from southern France, like lavender, marjoram, rosemary, sage, savory, and thyme, do well in hot summer sun and poor but well-drained soil with minimal fertilizer. On the other hand, basil, chives, coriander (cilantro), and parsley thrive in richer soil with more frequent watering. Wise planting puts chives by your broccoli, kale, but away from peas if you are still growing some. Cilantro, a carrot family workhorse, discourages harmful insects such as aphids, potato beetles and spider mites, attracts beneficial insects when in bloom. Dill is a natural right next to the cucumbers since you will use the dill if you make pickles. They mature about the same time. Let some of your arugula, carrots, lettuces, cilantro bloom! Bees, and insect eating birds and beneficial insects love them and you will get some seeds – some for the birds, some for you, some to swap! Grow beauty – cosmos, marigolds, white sweet alyssum – all benefit your garden in their own way!

…each a miracle of seed and sun, I’ve always been one to enjoy tomato or cucumber right off the vine, with never a trip into the house—one magical wipe down a shirt-front and they’re ready.. ~ commenter Rachel

Disease Tomato Fusarium Wilt Fungi Resistant

You may have had your own tears, and understandably so. Late Blight of potatoes and tomatoes was the disease responsible for the Irish potato famine in the mid-nineteenth century. Spores are spread by rain/watering splash, insects, and wind, and through our hands and tools and through these mediums they can travel distances. Spore spread is most rapid during conditions of high moisture, marine layer days, and moderate temperatures, 60°-80°F.  Once established, the fungi can over-winter in your garden soil, on debris and weeds.

Fusarium Wilt is commonly found throughout the United States, is a soil-borne pathogen. Plants susceptible to Fusarium Wilt are cucumber, potato, tomato, eggplant, pepper and beans. Fusarium wilt causes foliage to yellow, brown spots on leaves, leaves to curve the length of the leaf, wilt, then turn brown and die. Your plants become stunted because they can no longer function properly.

The list of plants susceptible to Verticillium Wilt is impressive. You might have thought it was just tomatoes, but look: Peanut, Horseradish, Rutabaga, Cabbage, Brussels sprouts, Pepper, Safflower, Hemp, Watermelon, citron Cantaloupe, honey dew, Pumpkin, Cotton, Okra, Mint, Radish, Rhubarb, Castor bean, Eggplant, Potato, Spinach, New Zealand spinach, SaIsify, Yard-long bean, Cowpea! Cucumber, tomatoes and strawberries are particularly susceptible.

Verticillium wilt is most active in humid climates. Cool nights and moist conditions, the kind that favors peas, tend to encourage it. It lives in the soil, entering plants through the roots and is drawn up to stems, leaves and fruit through water uptake. At the same time, it is robbing the plant of moisture. The first symptoms of verticillium are usually seen in wilting, yellowing and curling leaves. Discolored streaks are often seen in strawberry stems and runners, and in berry canes.

To determine if a plant is infected with bacterial wilt, press together two freshly cut sections of a stem and slowly pull them apart. If a “stringy” sap (bacterial growth and associated resins) extends between the cut ends, the plant has bacterial wilt.

Especially Tomatoes! And of those, Heirlooms are particularly susceptible to the wilts. Instead, get varieties that have VFN or VF on the tag at the nursery. The V is for Verticillium, the F Fusarium wilt, N nematodes. Ace, Early Girl, Champion, Celebrity, are some that are wilt resistant/tolerant. In these drought conditions, consider getting only indeterminates. In the Mother Earth News tomato survey, they found gardeners chose heirlooms over hybrids if their soil is wilt/blight free. Otherwise, the longer the gardener has gardened, they more they chose wilt resistant toms if their soil has the fungi.

Western striped cucumber beetles are deadly to cucumbers. They are referred to as ‘plant-wounding insects’ and also transmit bacterial wilt. Feeding on blossoms and leaves, they carry the wilts and also spread it among squash, melons, and pumpkins. Cucumber beetles also vector viruses such as cucumber mosaic but do so much less efficiently than aphids. Spiders are one of the predators that eat the beetles. Let those spiders live! A tachinid fly and a braconid parasitoid wasp parasitize them. Grow plenty of flowers for these beneficial insects!

Radish have become my new religion! Radish repel the beetles! You do have to plant your radish ahead of installing your transplants or have it up before the seedlings start growing from seed. Grow your radish companion along where you will let the vine travel. The part of the vine growing up over an arch won’t be helped, so if you have space and infected soil, you may opt to keep your vines on the ground. Plant enough radish so you can eat some, but let  some grow out so the whole plant is big and protecting your cukes and other vines. Broccoli also repel cucumber beetles. Grow cucumbers under over summering Broccoli. Put in plenty of straw mulch to keep the brocs cool and the cukes off the ground. Whenever you see these beetles don’t fall for how cute they are. Squish.
Transplant rather than direct seed! Tiny seedlings are most susceptible to cucumber beetle feeding damage and to bacterial wilts.

Washington State Extension says:

Apply straw mulch! Straw mulch can help reduce cucumber beetle problems in at least 3 different ways. First, mulch might directly slow beetle movement from one plant to another. Second, the mulch provides refuge for wolf spiders and other predators from hot and dry conditions, helping predator conservation. Third, the straw mulch is food for springtails and other insects that eat decaying plant material; these decomposers are important non-pest prey for spiders, helping to further build spider numbers. It is important that straw mulch does not contain weed seeds and to make certain that it does not contain herbicide residues which can take years to fully break down.

Cucumber Beetles have their preferences! Bitter is their favorite. Not interested in watermelon at all, but watermelon does get the wilts, just from other sources! Anyway, see more details and rankings of varieties of different kinds of veggies. Varieties make a huge difference.

Special Planting and growing tips! 

  • Regarding soil fungi like Fusarium and Verticillium wilts/fungi, how you care for cukes and toms is super important! Cucumbers are even more susceptible than tomatoes to the wilts fungi, die pretty instantly, in about 3 days, if they get infected. So when you plant them, treat them similarly to your tomatoes if you have wilts fungi in your garden.
  • Plant cukes and toms on a raised mound/basin with the bottom of the basin above the regular soil level. This allows good drainage. Top that with a 1/2″ of compost, cover that with only 1″ of straw to let in air and sun to dry the soil. Keep the LEAVES OFF THE GROUND from the get go. Leaves touching the soil is the main way toms get the wilts. Remove lower leaves that might touch soil when weighted with dew or water from watering. Keep a regular watch for new foliage at ground level and remove it. AVOID WATER SPLASH when watering at ground level. The fuzzy damp leaves of toms and eggplant are perfect fungi habitat.
  • When they are about a foot tall, water neighboring plants, but not your toms.  That keeps the soil drier near your plant, so the fungi can’t thrive there. Since toms have a deep taproot, they will get plenty of water from what you give neighboring plants. Water near them but not at them or on them. In fact there are farmers who dry farm tomatoes! Read more!
  • If you are comingling beans with cukes lower along a trellis, plant the beans between the raised cucumber mounds. Beans don’t get the wilts, but love the water, so lower is good. They are a big plant with continuous high production and short roots that need to be kept moist. Mulch ASAP with straw under cukes to keep leaves and fruit off the ground, and out of the insect zone. Put a stake in the middle of the basin so you know where to water when the leaves get dense. Water gently below the leaves at ground level, no splash. Keep those leaves dry. When your plant gets bigger you can remove lower leaves.
  • Since the fungi are airborne as well as soil borne, plant in different places as far apart as possible. Plant so leaves of one plant are not touching another plant. Remove sickened foliage ASAP to reduce fungi population and slow spreading. Prune on hot, dry, unwindy days, mid morning to midday, after dew has dried, so cuts can dry and heal with less chance of airborne fungi getting into them. Try not to touch the cuts after they have been made.  Use clippers for a clean cut. Wash your tools and hands often.Trimming away infected leaves is a sad and tedious process. It’s practically impossible not to spread the fungi as your touch leaves that have it and try to remove them without touching any other stems or leaves. The very cuts you make are open to fungi. Then, naked stems are susceptible to sunscald – see image below. You come back a few days later and more leaves are wilting. The disease is internal, has spread out to the leaves. At some point soon after that, a lot of gardeners pull the suffering plant. It’s done. Not good to leave it and let windborne fungi infect neighboring plants.

    Do not compost infected plants or trimmings. The fungi has amazing survival ability and being soil borne, it is right at home in your compost. Put it in the trash, carefully bagged so as not to spread or leave any trace. Wash your hands. If you can, burn the infected plants.

  • The wilts can’t be stopped. Sooner or later the plant leaves curl lengthwise, get the dark spots, turn brown then blacken and hang sadly. Plants can produce but the fruit doesn’t ripen properly if it does produce. It’s agonizing to watch. Sometimes they somewhat recover later in the season after looking totally dead. You had stopped watering them, summer heat dries the soil and kills enough of the fungi for the plant to be able to try again. But production is so little and fruits don’t ripen properly. It’s better to pull it, reduce the fungi population that can blow to other plants. The safest bet is to remove the entire plant. Get all of the root as best you can. The root is where the wilt’s mycelium first congregate and infected roots left in the ground will start the whole process again. Replant in a different place if possible.

Tomatoes pruned to remove diseased leaves of Fusarium and Verticilllium wilts are susceptible to sunscald.Preventive Foliar Mix that can help! 

Apply to newly installed transplants, and during the season every 2 to 3 weeks, so new growth will be covered. Wet both the undersides and tops of leaves. Per gallon add:

  • One dissolved regular strength aspirin
  • 1/4 Cup nonfat powdered milk
  • Heaping tablespoon baking soda
  • 1/2 Teaspoon mild liquid dish soap

After the tomatoes set, add some nitrogen. Boost your plant’s immune system with some worm castings at the same time. You don’t want to add too much nitrogen to your tomatoes before they set fruit. Too much nitrogen before fruiting leads to more leaves and less fruit. Add N only once. Stressed plants are the most susceptible to the fungus. Water regularly and deeply. Use well-balanced, slow-release organic fertilizers that aren’t overly heavy with nitrogen. A healthy plant tends to fight off the spores.

Blight can also be transmitted through seed, so NO seed saving from infected plants. Fresh seeds and resistant varieties are in order.

Remove volunteer tomatoes and potatoes. If they are a not a resistant or tolerant variety, when they get sick, they increase the chances of your resistant varieties having to fight harder to live, and your good dear plants may not win the battle.

Air circulation, plant staking and no touching. Air circulation allows the wind to blow through your plants. This allows the timely drying of leaves and it helps break up micro climates. If your plants are packed too tightly together, they themselves become barriers to drying. Staking your plants to poles and using cages helps them grow upright and it creates gaps between the tomato plants. You want wind and sun to reach through and around your plants. Moisture is needed for fungi to spread. Dry is good. Tomatoes should be planted with enough distance that only minor pruning is needed to keep them from touching each other.

Spray proactively. Wettable sulfur works. It is acceptable as an organic pesticide/fungicide, is a broad spectrum poison, follow the precautions. It creates an environment on the leaves the spores don’t like. The key to spraying with wettable sulfur is to do it weekly BEFORE signs of the disease shows. Other products also help stop the spread. Whatever you select, the key is to spray early and regularly.

At the end of the season remove all infected debris, don’t compost. Don’t leave dead tomato, eggplant or peppers in the garden to spend the winter. Pull weeds because spores can over-winter on weed hosts. Many weeds, including dandelions and lambsquarters, are known to host verticillium wilt. During our winter season, turn your soil about 10 inches deep. Let the soil dry and the fungi die. Burying the spores helps remove them, it disturbs cucumber beetle eggs and exposes snail eggs to die!

If you have space, crop rotation is an important tool in fighting wilt. If you’ve had trouble with wilt, don’t plant potatoes, eggplant, or other solanaceous vegetables where any of them have grown for at least four years.

Practice prevention, be vigilant. If you don’t have wilts in your soil you are so blessed!

Broccoli, the Queen of Brassicas! Rancheria Community Garden Dec 2016

Radiant Calabrese Broccoli, Rancheria Community Garden, Santa Barbara CA Dec 2016!

Broccoli may be the most nutritious of all the cole crops, which are among the most nutritious of all vegetables. Researchers have reported that cruciferous vegetables contain potent natural anti-cancer agents if eaten rawThese nutrients typically are more concentrated in flower buds than in leaves, and that makes broccoli and cauliflower better sources of vitamins and nutrients than cole crops in which only the leaves are eaten. The anti-cancer properties of these vegetables are so well established that the American Cancer Society recommends that Americans increase their intake of broccoli and other cole crops.

Recent studies have shown that broccoli sprouts may be even higher in important antioxidants than the mature broccoli heads. Other research has suggested that the compounds in broccoli and other Brassicas can protect the eyes against macular degeneration, the leading cause of blindness in older people. If you choose to eat broccoli leaves, you will find that there is significantly more vitamin A (16,000 IU per 100 grams) versus flower clusters – the heads (3,000 IU per 100 grams) or the stalks (400 IU per 100 grams).

They are also high in vitamin C, which may protect against atherosclerosis.  Four ounces of RAW broccoli contains twice the vitamin C in an equivalent amount of reconstituted orange juice. Cooking halves the amount of this vitamin.

Vegetarians rely heavily on broccoli because it’s high in calcium.

Early Purple Sprouting Broccoli, English HeirloomVARIETIES

Broccoli varieties vary considerably, tall, short, more heat tolerant or cold tolerant, have small heads, large heads, some make tons of side shoots, others less! For smaller heads, grow quick maturing varieties. They come in Green or purple! Purples turn green or blue when cooked. At left is an Early Purple Sprouting Broccoli, a beautiful English Heirloom producing like crazy!

Besides regular brocs, there are fancies like Romanesco that grows in a spiral! It’s taste is mild and more like cauliflower than broccoli. Sprouting broccoli has a larger number of heads with many thin stalks. Broccoli Raab, aka Rapini, is fast-growing, also known as turnip broccoli, forms multiple small heads and tends to branch out.

Some favorite varieties:

DeCicco 48-65 days – Italian heirloom, bountiful side shoots. Produces a good fall crop, considered a spring variety.  Early, so smaller main heads.
Packman 53 days – early hybrid, 9” head! Excellent side-shoot production.
Green Comet 55 days – early; hybrid, 6” diameter head, very tolerant of diseases and weather stress. Heat tolerant.
Nutribud 55-70 days – is unusually high in free glutamine which is one of the building blocks of protein, a primary energy source of the brain and a major healing nutrient! Purple broccoli, in addition to this, contains anthocyanins which give it its colour. These have antioxidant effects, which are thought to lower the risk of some cancers and maintain a healthy urinary tract as well.
Cruiser 58 days – tolerant of dry conditions
Calabrese 58-90 days – Italian, large heads, many side shoots. Loves cool weather. Disease resistant.
Green Goliath 60 days – heavy producer, tolerant of extremes. Prefers cool weather, considered a spring variety.
Waltham 29  85 days – medium heads, late, cold resistant, prefers fall weather but has tolerance for late summer heat.

Broccoli is notorious for uneven maturity, so you will often see a range of days to maturity, like Calabrese above. So don’t expect clockwork. The advantage is they don’t come in all at once and you have table supply for an extended period, especially if you plant different varieties at the same time. After the main head is harvested, you will have an abundant supply of side shoots which will further extend your harvest time. Some varieties even produce mini side shoots at the same time as the main head!

Companion Plants Broccoli Lettuce repel Cabbage MothTasty image from GrowVeg!

COMPANIONS

Plant Lettuce amongst the Brassicas to repel cabbage moths. In hot summer, big brocs shelter and shade delicate lettuces. When it isn’t hot, put smaller companions on the sunny side of your brocs. Cut lower foliage off so they get sun. Mint nearby deters cabbage moths from laying eggs. Since mint is invasive, plant it in containers.

Cilantro makes broccoli grow REALLY well, bigger, fuller, greener!

To deter pests plant Onion family, plant Chamomile, Aromatic herbs, especially Catmint, Hyssop, Mint, Dill, Sage, Thyme, Lavender, Lemon Balm. Plant your herbs in containers so they can be moved around during the year to help specific seasonal plants.

Generally brocs are happy with Basil, Beans, Beets, Celery, Chard, Cucumber, Dill, Garlic, Lettuce, Marigold, Mint, Nasturtium, Onion, Potato,  Radish, Rosemary, Sage, Thyme, Tomato

Not happy with Tomatoes?, strawberry, lettuce?!, bush & pole beans.

In summer, plant cucumbers under them to reduce the attraction of striped cucumber beetles to the cukes.

Radish reduces green peach aphids.

Be advised! Dying parts of the Brassica family of plants produce a poison that prevents the seeds of some plants from growing.  Plants with small seeds, such as lettuce, are especially affected by the Brassica poison, so plant lettuces from transplants under them. A professor at the University of Connecticut says Brassica plants should be removed from the soil after they have produced their crop.

PLANTING

Brocs prefer full sun, though partial shade helps prevent bolting, but if they don’t get enough sun they will just grow tall. More sun helps make a tougher plant less attractive to aphids.

Broccoli plants will grow in almost any soil but prefer a pH between 6.0 and 7.0 for optimum growth. A pH within this range will discourage clubroot disease and maximize nutrient availability. Well-drained, sandy loam soils rich in organic matter are ideal for broccoli plants and especially early plantings of broccoli. They LOVE recently manured ground.

If you will be planting by seed, per Cornell, best germination temperature is 45 F to 85 F, but will germinate at soil temps as low as 40 F.

Though those are best temps, in SoCal, if there are no Bagrada Bugs, fall plantings are started late July. While there is little space for big winter plants, small nursery patches can be planted. Leave enough room between seedlings so you can get your trowel in to lift them out to transplant later when space becomes available. If seeds and nurseries aren’t your thing, wait until your local nursery has transplants! If we aren’t having a heatwave, late August they might start trickling in. Labor Day weekend is a favorite planting time for some gardeners. October is just fine too!

Successive plantings may be done all winter long. If brocs are a favorite, the last round is usually planted in January because spring brings the interest in summer plants and we need room for them! We need space to amend soil for the next plantings, and time to let it settle and for the soil organisms to establish and flourish. The weather shifts, our body shifts with the seasons and we are looking forward to those summer treats again!

Seedlings should be 8″-10″ apart with 30″-36″ between the rows. Broccoli yields and the size of broccoli heads are affected by plant spacing. The tighter the spacing the better the yields, but the broccoli heads will be smaller. If you intend to keep your plants for side shoots, plant taller varieties to the northmost so they won’t shade shorter summer plants you will plant later on. Plant for plenty of air circulation to help avoid mildew.

The number of plants you choose to grow depends on your needs. If Broccoli is a staple for you, plant plenty so after the main heads are taken, you will get enough side shoots. When you need space for summer crops, and as other crops come in, you may decide to keep only 1 or 2 plants for side shoots to garnish your summer salads.

Cool weather is essential once the flower heads start to form. It keeps growth steady.

MAINTENANCE, IRRIGATION/MULCH

For year ’round growers, mulch early in spring to keep the ground cool and moist as well as reduce weed competition. In cool moist areas, forget the mulch. It brings slugs.

An even moisture supply is needed for broccoli transplants to become well established and to produce good heads. Never let the seedbed dry out. In sandy soils this may require two to three waterings per day. When they get up to about a foot tall, lay back on the water so the leaves aren’t too soft, attract aphids.

Compost/Fertilizer Put a ring of granular nitrogen around cabbage, broccoli and cauliflower plants for bigger heads.

The trick to producing excellent broccoli heads is to keep the broccoli plants growing at a steady pace. Top-dress the plants with compost or manure tea; or side-dress with blood-meal or fish emulsion; and water deeply. Repeat this process every 3-4 weeks until just before harvest.

PESTS & DISEASES

Pests

Research shows there are less aphids when you plant different varieties of brocs together! The plants mature at different rates. Aphids usually mean too soft a plant. Less feeding, less water. Immediately check curled leaves. Spray them away with a vigorous stream of water every day until gone, taking special care where new leaves are forming. Check the undersides of the leaves too. If the aphids have infested side shoots, remove the shoots. Some recommend sprinkling cinnamon on the ground to dissuade the ants that tend the aphids.

Cutworms, Flea Beetles, and Diamond Back Moth.

The nemesis is the green looper! This cabbage caterpillar makes your plants holey faster than thou can believe! Get Bt, Bacillus thuringiensis. It is sold in nurseries as Thuricide, Dipel, Bactus, Biological Worm Control, Leptox, SOK, Novabac or Tribacture.

Diseases

Club Root, Black Rot, Black Leg, Wirestem, Alternaria Leaf Spot, and Downy Mildew

Immediately when you plant your transplants, treat for mildew. Apply your baking soda mix. Drench under and upper sides of the foliage of young plants to get them off to a great start! A super combo is 1 regular Aspirin dissolved, a 1/4 cup nonfat powdered milk, heaping tablespoon of baking soda, a teaspoon liquid dish soap per gallon/watering can. Reapply every 10 days or so, and after significant rains. Prevention is so much better than after mildew has set in. See Aspirin Solution.

Small or no heads? Weather can be the culprit. Per Bonnie Plants, “If transplants sit exposed to cold below 40 degrees for a week or two, the chilling injury triggers heads to form way too early.” A small head on a small plant means you won’t get a large head. A head may not form If the growing tip is injured by rough handling, insects or weather. Your broc is considered to have gone ‘blind.’ If you have enough growing season time left, start over with a transplant if possible.

HARVEST

Potentially you have five kinds of harvests! Leaves, heads, side shoots, flowers, seeds! Leaves are edible, same as collards!

The center head produced by broccoli is always the largest. Harvest the main head while the buds are tight!  Broccoli heads should not have any yellow petals. Cut about 5” down the stem so fat side branches and larger side shoots will form. Cut at an angle so water will run off, not settle in the center and rot the central stalk.

Side heads will develop rapidly in some varieties after the main head has been harvested, some even before! Harvesting of the broccoli side heads may continue for several weeks or all summer! Side shoot heads are 1 to 3″ in diameter. Sidedressing with fertilizer can increase yields and size of these sprout shoots.

Broccoli is highly perishable. The respiration rate of freshly harvested broccoli is very high. Harvest it last, and get it into the fridge asap before it goes limp! Broccoli should not be stored with apples or pears, which produce substantial quantities of ethylene, because this gas accelerates yellowing of the buds. Freeze what you won’t use right away.

If you didn’t harvest your side shoots and your broccoli has gone to flower, harvest the flowers and sprinkle them over your salad, toss them in your stir fry for a little peppery flavor! Hold the stalk with one hand, zip your other hand along the stalk to gather the beautiful flowers! Clip off stalks you don’t need and you will likely get more side shoots!

Broccoli Seed SaveSAVING SEEDS

All varieties in this large species will cross with each other. Separate different varieties at least 1000 feet for satisfactory results or at least 1 mile for purity. Caging with introduced pollinators or alternate day caging is also recommended in small gardens. Because Brassicas are biennial, two year plants, plants to be left for seed production, if in cold climates, should be mulched in the fall or carefully dug, trimmed and stored for the winter in a humid area with temperatures between 35-40° F. In SoCal they can be left in the ground to overwinter. Flowering plants can reach 4′ in height and need at least 2′ to 3′ spacing, depending on the size of the variety, for good seed production.

Broccoli, cauliflower, cabbage and kohlrabi grown for seed should not be trimmed for consumption. Brussels sprouts, collards and kale can be lightly trimmed for eating without affecting quality seed production. If small amounts of seeds are wanted, allow the fine little pods to dry to a light brown color before picking and opening by hand. Lower pods dry first followed by those progressively higher on the plant. Watch daily to get them before the birds do, or cover the plant with bird netting! For larger amounts of seeds pull the entire plant after a majority of pods have dried. Green pods rarely produce viable seeds even if allowed to dry after the plant is pulled.

Crush unopened pods in a cloth bag with a mallet or by walking on them. Chaff can be winnowed. Remove the seeds so no moisture will remain to rot them.

Viability  2 – 3 years, but up to 5 years in good cool and dry storage conditions.

CULINARY TREATS!

Broccoli is a popular raw hors d’œuvre vegetable for good reason! That is when it is most nutritious! Light and quick steaming is second best.

All Brassica leaves can be eaten the same as collard leaves! Steamed over rice, or toss in a wok with oil, sprinkled with soy sauce or a sauce of your choice. Dr. Amy Simmone, University of Florida Food Safety Specialist and native of Thailand, states that in her country broccoli leaves are stir-fried or sautéed with garlic and oyster sauce and served with rice. She says that broccoli leaves taste a bit like young tender collard greens.

Use to top pastas or even pizzas! Broccoli along with almonds makes a delish creamy soup. Cheese and Broccoli Quiche!

Broccoli Bright Beautiful Edible FlowersThe top portion of broccoli is actually flower buds. Given time each will burst into a bright beautiful yellow flower, which is why they are called florets. The small yellow edible flowers have a mild spiciness, mild broccoli flavor. They are quite pretty and terrific sprinkled on salads, and are delicious in a stir-fry or steamer.

Tarladalal of India says: Combine broccoli, baby corn, spinach and other vegetables of your choice, cook in a thick creamy white sauce or red sauce. Pour in a baking dish, garnish with cheese and bake to make au gratins. You can also use as lasagna sheets in this recipe.

Broccoli has been with us in the US since 1923, when two Italian brothers planted the first crop near San Jose, California. John Evans, of Palmer, Alaska, holds the 1993 world’s record for his 35 lb (no typo) broc!  He uses organic methods, including mycorrhizal fungi!  And, yes, moose eat broccoli!

Tomatoes Harvest Basket
Love your Mother! Plant more bee food! Eat less meat. Grow organic!

Keep harvesting, it keeps your plants producing! Canning, freezing, fermenting, storing, drying are on the agenda! Check up on your winter squashes to see if they are ready to harvest and store. It’s SeedSaving time!

Though crazy busy with harvests, gardeners have fall planting on their minds. Among HOT August days, there are ones that have a hint of fall. Days are a tad shorter; shadows in different places now. As summer plants finish, nursery bed areas are becoming available. The soil is being prepared for first fall plantings now through mid August, especially from seed! Often these special nurseries are made in semi shaded areas, seedlings to be transplanted as they get bigger and permanent spaces become available.

Plant your seeds far enough apart to get your trowel in to pick up your little plants to move them one by one to their new homes. Some are planted under finishing plants to take the finishing plant’s place, like peas under beans. Pop in some baby kale or cabbage between the tomatoes and peppers. Safe in a greenhouse is wonderful too!

Already, get your seed packs for celery, chard, mustard greens, parsley, peas, winter radish varieties, and Brassicas: cabbage, brocs, Brussels sprouts, collards, cauliflower, kale babies, kohlrabi, turnips. See Super Fall Veggies for help on choosing the very best varieties and Fall companion planting! Winter plants that get a good start while there is still some heat, will be producing a lot sooner than plants started while it is cooler, and you will have a much earlier crop. Be sure to leave space to plant additional rounds to keep steady table supply.

If you have Bagrada Bugs, wait until cooler October, when the bugs are gone, to plant Brassicas. That includes arugula, mustards, radish. See more about Bagrada Bugs management.

If you don’t have time to fuss with seeds, will be away at the critical time, keep harvesting, do your soil preps, and wait for September or October transplanting. Labor Day weekend is a favorite big planting time for many gardeners, and that’s only a month away now! At that time you can plant both seeds and transplants for two rounds at once, the seeds coming in six weeks after the transplants!

Summer plants you can still plant for early fall harvests, are beans and early maturing tomatoes and corn. Corn is more disease prone at this time though.

Tuck in your year-round fillers, beets, bunch onions, carrots, summer lettuces, winter radish, to keep a colorful variety for your table.

ONIONS For the biggest, sweetest harvests, late summer and early fall are the prime times to sow seeds of short- or intermediate-day onions. Fall-sown short- and intermediate-day onions tend to yield more and are larger and sweeter than those seeded or transplanted in early spring. Onions have stupendous flavor and come in white, yellow, red!

Give your late favorite summer/fall heavy producers you are keeping a good feed. Eggplants have a large fruit, beans put out a ton of beans, tomatoes are big and working hard, peppers can be profuse! They like a tad of chicken manures scratched in, bunny poop and straw (pick up at Animal Shelters), well aged horse manure and compost makes them dance with the faeries in the night time! Fertilizers highest in P, Phosphorus, keeps blooming and fruiting optimum. Peppers specially like a foliar feed of non-fat powdered milk (Calcium) and Epsom Salts (Magnesium & Sulfur). They also can use more Potassium. This time of year kelp meal is good source and releases quickly. If you have predators about, don’t get the kind mixed with fish emulsion.

Keep your watering steady, out to the dripline, to avoid slowing or stopping production or having misshapen fruits – that’s curled beans, odd shaped peppers, catfaced strawberries. Keep your soil moist. In hot late summer weather water short rooted high production plants like beans, cucumbers, lettuces and strawberries more frequently. Keep them well mulched, especially the cucumbers. Keep them off the ground to protect them from suffering wilts fungi. I put down straw a good 3″ deep.

In our hot foothills and further south, watch your melons, big squashes and pumpkins for their best harvest time – when their stem is brown and dry, or they ‘slip’ off the vine. Hold off irrigating melons about a week before they will ripen so their sugars will concentrate. Harvest okra while it is small and tender – bigger is NOT better! Let your winter squash harden. When you can’t push your fingernail in it, it’s ready.

In the cool of summer evenings design your fall garden! Move plants from the nursery area as space becomes available, but have a plan too. Tall plants, trellises, to the North or on the shady side, then plants of graduated sizes to the South or sunniest areas. Peas need a string or wire trellis for their tiny tendrils. They aren’t like beans that twine anything. Few winter plants need support, but big brocs, tall kales sometimes need staking. If they ‘lay down,’ if you have the room and want more plants, they will grow baby plants along their stems! Otherwise, put your plants back up and stake them securely. Build your new raised beds. Install gopher barriers!

Think soil, soil, soil! When an area is done, clear away insect hiding places. Remove and throw away any mulches from under where diseased plants were. If your soil is high for the area, plants there were diseased, and you have plentiful compost, maybe remove the couple top inches of soil and generously lay on some of that tasty new compost! Dig it into the top 4 to 6 inches. Amend your soils per the plant that will be grown in the area per your design. Strawberries need acidic compost IN the soil.

Keep turning your fall compost pile, start one if you haven’t! This warmer weather will help the pile decompose faster, and your plants will be blessed when you give the compost to them! If you aren’t hot composting, remember, thin layers and smaller bits decompose faster. The ratio is 1 wet/green to 2 dry/brown. Throw in whatever kitchen trim, torn tea bags, coffee filters/grounds, crushed eggshells – anything worms can eat will decompose faster.

I’m talking faster because starting now is a little late, so this is what you do to ‘catch up!’ Sprinkle with a handful or two of living moist soil to inoculate your pile, and add handfuls of decomposer herbs like comfrey, yarrow, chamomile. Turn it as often as you can to aerate and keep things humming. Vigorously shovel chop into smaller pieces as you go. Once a day if possible, but do what you can. I do mine anywhere from three days to every two weeks as I have time. Compost improves your soil’s water holding capacity and adds and stabilizes N, Nitrogen! Yes!

SeedSaving! Allow your healthiest top producers to seed. Seeds are your second harvest! Each year keep your best! Scatter some about if they would grow successfully now! Or just scatter them about and when it’s the right time, even next spring, they will come up. Store your keepers in a cool dry place for next year’s better than ever plantings. Remember, these seeds are adapted and localized to you! If you are willing, take your extras to a local Seed Bank! While you are there, pick up some of your fall favorites and some new ones to try out!

4th July US Flag Woman Garden Seeds Independence

Gardening is civil and social, but it wants the vigor and freedom of the forest and the outlaw.  –  Henry David Thoreau

Important Habitat!

X

Let a carrot or two, a celery, and some cilantro bloom out! The blooms will be food for and bring beneficial insect pollinators. Birds will have seeds for food and scour your plants for juicy cabbage worms, whiteflies, aphids, earwigs, grasshoppers, cucumber beetles and grubs fresh for their hatchlings! Chickadees even eat ants!

Planting!

Some planting is always doable in July, and very last rounds of summer favorites! Transplant basil, celery, chard, cucumbers, dill, kale, leeks, summer lettuce, green onions, white potatoes, summer savory, New Zealand spinach. In our hot foothills and further south, go for more melons, okra, pumpkins, summer & winter squash. Corn is an exception – late plantings often develop smut. I’ve seen tomato transplants and bean seeds started in August produce plentiful crops into October!

Fall transplants need babying! Transplant late afternoon or evening so plants have the whole night to begin to recover before they’re hit with a full day of sun and heat. Water well and provide shade from intense mid-day sun. Prop up and secure some of those plastic plant flats that have the finer pattern to filter the light. Keep your transplants moist for at least a month or until they’re well established. Mulch to save water unless you have Bagrada Bugs.

At the end of the month, sow carrots (they do best from seed), celery and, if no Bagrada Bugs, Brassicas. If you have the Bugs, wait until it cools in October. Brassicas are arugula, broccoli, Brussels sprouts, cabbage (especially red and savoy types, which resist frost better), cauliflower, and kohlrabi, mizuna, mustard, pac choi, radish, rutabaga, turnip. Keep the soil moist and shaded until they’re up, and then gradually allow them more sun over a week’s time.

Harvest and Storage Tips!

Pluck those tasty veggies when they mature.

String Beans Harvest just about daily. If they bulge with seeds and start to dry, your plant thinks it’s done and stops producing. Pick, pick, pick!
Corn When the silks turn brown and you push your fingernail in a kernel and it squirts milky juice, it’s ready! It holds its sweetness only 2 to 5 days! Harvest early in the day, make time to your fridge or the barbie because the sugars turn to starch very quickly!
Cucumbers – no storing on the vine. Your plant thinks it’s done. Cut, clip or carefully twist off while carefully holding the vine.
Melons Harvest sooner by placing ripening melons on upside down aluminum pie pans or cans to keep them off the damp soil. The reflected heat and light will help them ripen evenly and sooner than when they are shaded by foliage.
Okra! If your summer has been hot enough you got some! It must be harvested before it gets tough. Letting it get bigger simply doesn’t pay. So look carefully for mature fruits and take ’em! I grow the burgundy and ruby types, slice them fresh over my salads. Pretty little stars. 
Peppers
– depends on the pepper. Let them stay on the plant if you planted ones for pretty colors. Cut or clip them off so not to damage your plant. Quick-freeze ones you won’t be using right away! Slice, dice, and freeze in baggies in the amounts you anticipate using in a stir fry or stew.
Potatoes are ready for digging when the plant flowers. Wet up the soil and dig about for the biggest ones, leaving the others to get sizable for another later harvest.
Tomatoes when they are the color you chose. Bend cherry toms back so you get the cap and stem. This keeps them from splitting open. O’ course, if they split, you absolutely must eat them on the spot so they don’t spoil! No problem freezing toms whole! Just remove the stem core. You can blanch them and remove the skins first, or not…your choice.
Zucchini  Harvest in self defense! They get BIG, FAST! Some of you came from big families and like baking them and would never think of harvesting them until they are huge, lotsa bang for your buck! Others have a family of 1, can’t possibly eat all that zuke, so harvest them quite small, fresh salad slicing size. The ridged types make pretty little star shaped slices!

Strawberries are a little different. Quickly as possible, store fresh picked berries in a container lined with a paper towel in the coldest part of your fridge. They will last about a week, but it’s more fun to eat them sooner!

If you don’t need or want any strawberry runner babies, pinch off the runners so your plant’s energy goes to fruiting. If you want to start a new November bed, let the runners grow now to the size you want, put pots nearby, anchor the runner in place, let them root in the pot, container. When they are doing well on their own, clip the connection to the Mother plant. The babies nearest the Mother are the strongest. Clip off the ones further away. Start your new bed with them or give them away.

Your SECOND HARVEST is SEEDS! As July goes on or in August, when you or your plant are ready, let your very best plants produce but don’t harvest the fruits. Beans get lumpy with seeds and will dry completely. Let them dry on the vine for full nutrition from the mother plant. Let a cucumber yellow and dry. Let the corn cob dry and the kernels get hard. Cukes, peppers, melons, okra and squash are easy. Just remove the seeds and let them dry. Uh, do label the drying trays! Tomatoes are a tiny bit of a process but not hard at all. See more!

Save enough seeds for your own planting, for several rounds of planting across the next season, for replanting when there are losses, and some to give away or share at a seed swap. Keep the race going.

Keep up with Sidedressing and Watering

Compost and worm castings are important for more than as soil builders. Compost has super water holding capacity, and as some of us get tired toward the end of summer, and it is hotter, our soil needs compost more than ever, especially if you want to extend production time.

Worm castings help our plants uptake soil nutrients and boost your plant’s immune system. When your plant is taxed producing fruit in great summer conditions, it also is peaking out for the season and fighting pests and diseases are harder for it. And, sometimes a plant is just done. No amount of coaxing will have effect. It worked hard. Thank it and take it to the compost altar.

Manures are great for all but beans, beets, carrots, parsnips, sweet and white potatoes, and tomatoes, or there’ll be more foliage than fruit!
Give your peppers and solanaceaes, tomatoes, eggplant, potatoes, Epsom Salt/Magnesium treatments.
Every couple of weeks your strawberries would love a light fish emulsion/kelp drench.

Don’t be fooled by Temporary High Temps! Tomatoes, peppers, eggplant, stop flowering and fruiting when temps rise above 85 to 90 degrees F (depending on humidity) for an extended time. Humidity causes pollen to stick and not fall to pollinate. Dry heat causes the pollen to fall and not stick! When weather cools, you will have blooms again and be back in production. Rattlesnake beans, on the other hand, keep right on producing at 100 degree temps! So choose heat tolerant veggie varieties, like Heatmaster and Solar Fire tomatoes, from locales with hot weather. They are out there!

Wise Watering  Keep up with even watering so fruits have their right shapes. Though June has the longest days of summer, July through September can be the hottest in SoCal. Be aware if you are overwatering. Plants vary in their needs and as temps vary. You can save 20 to 30% and have healthier plants!

Water being critical due to the drought, needs to be thoughtfully managed, just like for our lawns and landscapes. To mimic the Santa Barbara Stage 3 Drought Regs, see if you can apply these ideas to your garden. For example, build berms to keep water exactly where it does the most good. Berms need to go to the dripline of your plant so tiny feeder roots can fully supply your plant with water and nutrients as it needs.

  • Routinely check your irrigation system if you have one.
  • Hoses must be equipped with an automatic shut-off nozzle when in use. We can do that by using water wands with easy-to-use thumb valve shutoffs.
  • Irrigation with potable water is prohibited between the hours of 8:00 a.m. and 6:00 p.m. for automatic systems. If manually operated, such irrigation is prohibited between the hours of 10:30 a.m. and 4:00 p.m.
  • Irrigation with potable water that causes runoff onto adjacent property, non-irrigated areas, private and public walkways, roadways, parking lots, or parking structures is prohibited.
  • Any excessive, unnecessary or unwarranted use of water is prohibited.
  • All leaks must be repaired as soon as reasonably possible.
  • Irrigation during and within 48 hours after measurable rainfall is prohibited.

If you garden at home, please look into water capture and gray water systems, super attractive bioswale catchments. In Santa Barbara County there are rebates available! Do it now to be ready for winter rain. Also there are FREE landscape workshops! And we have FREE water system checkups. Call (805) 564-5460 to schedule today!

Fall Soil Preparation & Planting

Make compost with your finishing summer plants that are pest and disease free. Recycle that green gold! Make mini layers with that and veggie kitchen scraps that you and your friends save for you alternated with dry brown layers of straw or dried leaves. 1/2″ layers are the very best, 1″ layers are fine too. It goes one part wet/green to two parts dry/brown. The thinner the layers the faster your pile decomposes.

Soil Prep As your summer plants finish, spaces become available for fall planting prep. Amend your soil with what is needed for what you will plant there. Unless there are Bagrada Bugs, mulch the soil to protect what you have created, keep it moist. Remove mulch if Bagrada Bugs appear. They lay eggs in the soil and mulched soil is lovely safe habitat for them. Unless you have seen them in action, I can’t impress on you how quickly prolific they are.

Container and raised bed gardeners remove spent soil. Toss it out or use it as mulch somewhere else. Replace it and add tasty amendments – compost, manures, worm castings – for late summer and lusty fall plantings. The water warmer raised beds need washes nutrients away. How many times have you seen sunken dried up raised beds with only straggly plants remaining? If you decide to have a raised bed, you need to make the commitment. They are isolated from the natural daily goings on in ground level soil, so you have to help them. Ground level soils need amending, sometimes replacing, but much less than raised beds and containers.

Starting a Nursery Patch  It’s time to get seeds if you don’t already have them! While there is little space for big winter plants, small nursery patches can be planted. Leave enough room between seedlings so you can get your trowel in to lift them out to transplant later when space becomes available! If seeds and nurseries aren’t your thing, wait until your local nursery starts having the transplants that make you happy! August they might start trickling in. Labor Day weekend is a favorite planting time for some gardeners. October is just fine too!

Clean up funky pest habitat that the little buggers can overwinter in or while it is still hot they will multiply in.

July is a month to keep all your balls in the air! Planting, harvesting, caretaking, preparations! The payoff will be delicious harvests, and the promise of winter crops starting early in the season. Remember to leave space for second and third rounds for steady table supply. Plant quickly maturing veggies like lettuces and beets to have production in those waiting spaces until you are ready to plant those later rounds.

Think on when you want those October pumpkins and what you want on your table for ThanksGiving, maybe sweet potatoes and pumpkin pie! And at Christmas time, maybe a sauce over some of those delicious frozen beans or some fresh butterhead lettuce salad topped with cranberries. Plan for it!

May your table be bountiful and your Spirit radiant with exceptional health!

The Green Bean Connection started as correspondence for the Santa Barbara CA USA Pilgrim Terrace Community Garden. We are very coastal, during late spring/summer in a fog belt/marine layer area most years, locally referred to as the May grays, June glooms and August fogusts. Keep that in mind compared to the microclimate niche where your veggie garden is. Bless you for being such a wonderful Earth Steward!

Soil Thermometer Veggies

Soil temp is always your basic seed planting time guide!

There are minimum germination temps, ideal temps and max temps. Plant when soils reach minimum temperature measured at 8 a.m., 4 inches deep. Beans are an exception, being measured at 6 inches deep.

40 Degrees! Crops that germinate in the coolest soils: arugula, beets, broccoli, carrots, cauliflower, fava beans, kale, kohlrabi, leeks, lettuce, pak choi, onions, parsley, parsnips, peas, radicchio, radish and spinach seed.
50 Degrees:  Cabbage, Chinese cabbage, leeks, onions, Swiss chard, and turnips.
55 Degrees:  Corn, tomatoes.
60 Degrees warm-season vegetables: beans, beets, broccoli, Brussels sprouts, cabbage, carrots and cauliflower.
65 Degrees: Cucumber, peppers, cantaloupe
70 Degrees heat lovers!  Beans, corn, cucumbers, eggplants, melons, okra, peppers, squash, and tomatoes.

In northern climates it can take several weeks for tomatoes, eggplant and peppers to germinate in the garden. You can get a jump on the season if you do cold-tolerant, or if North, short-season variety transplants. Squash, cucumbers and corn grow quickly and are easy to start from seed.

Heat your soil with plastic mulch and use a cloche, fabric row cover or cold frame. The bane of early planting is a late hard freeze. If you decide to take an early season chance, have covers handy for unprotected plants!

We can thank Dr Jerry Parsons, Extension Horticulturist at the Texas Agricultural Extension Service, for the temps info in this great chart below! You see, there are minimum temps, optimum, and no-go temps! At the practical temps you might not get 100% germination, but you will get a crop at the right time. Too soon you get too little. Too late, like in SW desert areas or hot climates, there may be too much summer heat and little production, high water costs.

Notice that there are differences from the temps and plants listed above and the chart below, some plants appear in two temps, and some plants, like okra, might not be planted in the north at all! Dr Parsons has longer Texas heat in his area. Northern gardeners need to plant sooner for short cooler summers. Plant cold tolerant or early varieties. And, plant more seeds to compensate for those that don’t germinate. Or, presprout for more surety.

Regions have huge variances in planting time strategies, and even in the same yard there are micro niches that vary considerably, so get a thermometer and plant in the right place at the right time!

Soil Germination Temperatures Veggies Parsons

Start with fresh viable seed for great germination, and don’t forget your seed soaking & presprouting options!

With a Soil Thermometer and good gardener self discipline, get your seeds and plants in the ground at their most productive times for your location! Here’s to abundant harvests!
