15 Super Tips for a Productive Summer Veggie Patch!

Asymmetrical Design

Whether you are tucking things into niches between ornamental landscape plants, planting a patio patch like in the image, setting up a first time summer garden patch, or replanning your annual garden, here are some great ideas to increase your production!

1. If you have space, and are creating a back, or front, yard food forest, always start with your tree placements first! Determine which veggies grow well with each kind of tree. Santa Barbara Mediterranean Food Forests

2. Keep in mind veggies need sun! 6 to 8 hours, preferably 8! They are making fruit, and often many! That takes energy.

3.  Put tall plants to the north (see image below), so they won’t shade the shorties. If there is a partially shaded area, plant your tallest plants on the shaded side so they can reach up to get some sun; put the shorter plants in decreasing heights, in front of them so all get as much light as they can. When you are planting rounds, another batch every few weeks, start in the north or the ‘back’ – the shaded area, and work your way forward.

4. Trellises and tall cages are terrific space savers and keep your plants off the ground out of harm’s way – pests, diseases, damage. Your veggies will be clean, and have more even ripening. Cucumbers, beans, tomatoes. Squashes and melons can be trellised if you provide support for heavy fruits. Even Zucchini can be grown up through cages leaving a lot of ground space for underplantings. Harvesting is a lot easier and certain when those fast growing zuchs are up where you can see them!

Inefficient Single Row Planting

5. There are rows and there are rows! Single row planting wastes space! Compare the images. If you do rows, plant 2 or 3 different plants in side by side rows, then have your walk way, then another 2 or 3 plants together. Whether you do 2 or 3, or even 4, depends on plant size, your reach, and ease of tending and harvest. Plant taller or medium size plants, like peppers and eggplant, by twos so you can reach in to harvest. Plant shorter smaller plants like lettuces, spinach, strawberries together since they are easy to reach across to harvest. If plants in the rows are the same size, plant the second row plants on the diagonal to the first row plants. That way your rows can be closer together and you can plant more plants!

6. Rather than rows, biodiversity, mixing things up, confuses pests, stops diseases in their tracks, because they can’t just go from the same plant to the same plant down a row. Since we are not using tractors, there is no need for rows at all, but they can be lovely. The curved rows in the image are behind the Eden Project restaurant outdoor seating! Truly garden to table!

7. If you need only a few plants, rather than designating a separate space for lettuces and littles like radishes, tuck them in here and there on the sunny side under bigger plants! When it gets big enough, remove the sunny side lower leaves of the larger plant to let light in.

8. Plant what you like, and will really eat along with some extra nutritious chards, kales.

9. Plants with the same water needs are good together. Like a salad patch – lettuce, arugula, spinach, bok choy, bunch onions, radish, chards. Putting the things together that you will harvest together saves time! Put carrots at the foot of pole beans.

10. Overplanting can take the fun out of things. Too many zucchini in hot summers, and you are going crazy trying to give away the over large ones you didn’t harvest soon enough. Too many green beans are labor intensive harvesting, takes forever. Planting green beans too close together is hard to harvest, and they mildew more with low air circulation. Overplanting is delicious when you plant lots of lettuces, carrots then harvest what you thin out! That’s baby kales, chard, mini carrots. These are the eat-on-the-spot-in-the-garden types!

11. Traditionally, and if you lived in the North with cold winters, you planted the garden all at once in spring! If your parents did that, you are unthinkingly likely to do it as well. In our SoCal Mediterranean climate, we plant all year though there are warmer and cooler veggie seasons. But each of these seasons are longer, and overlap! It is easy to get 3 plantings in succession IN EACH SEASON! Some plants will grow all year, mostly the ‘winter’ plants in our coastal gardens, for example, beets, broccoli, onions and cabbages. It takes strength to leave open space for successive rounds. But you can do it. Mark that space off, plant temporary fast growers, nitrogen-fixing fava, or lay down some soil feeding mulch like seedless straw. That space will be super productive when its turn comes.

12. Pole plants, have a lot longer production period than bush, like beans! Indeterminate tomatoes are true vines, can last all season long, but are susceptible to Fusarium and Verticillium wilts/fungi diseases. Might be better to plant determinates, limited growth varieties, in succession. That’s plant a few, then in a few weeks a few more, and so on. Let the determinates produce like crazy all at once, pull them when they show signs of the wilts. If you have only a small space available, or want to do canning, then bush plants are for you!

13. Plants that act as perennials in our climate are smart money plants! Broccoli’s for their side shoots, continuous kales and chards.

14. Special needs or companions!

  • Eggplants, though heat lovers, love humidity, but not overhead watering. Put them among other medium height plants.
  • Basils are great on the sunny sides of tomatoes, and go to table together.
  • Corn needs colonies – plant in patches versus rows! Every silk needs pollination because each produces a kernel! The best pollination occurs in clusters or blocks of plants. Consider that each plant only produces 2 to 3 ears, usually 2 good ones. How many can you eat a once? Will you freeze them? The ears pretty much mature within a few days of each other! So, if you are a fresh corn lover, plant successively only in quantities you can eat.

15. Consider herbs for corner, border, or hanging plants. They add a beautiful texture to your garden, are wonderfully aromatic, repel pests! Remember, some of them are invasive, like oregano, culinary thyme. Sage has unique lovely leaves. Choose the right type of rosemary for the space and look you want.

Please be CREATIVE! You don’t have to plant in rows, though that may be right for you. Check out this Squidoo Vegetable Garden Layout page! Check out the Grow Planner for Ipad from Mother Earth News! They may make you very happy! This is a perfectly acceptable way to play with your food.

Strawberry Tips for Tasty Super Berries!

  • Strawberries are in the Rose family.
  • The average berry has 200 seeds, the only fruit whose seeds are on its exterior surface!  The seeds are really the fruit!
  • Usually grown from runner daughters, they will grow from seed.  Just throw down caps you bit the berry from.  Sooner or later, you will have a plant you didn’t ‘plant.’  Strawberry seed saving is simple.
  • Eight out of 10 strawberries grown in the U.S. are grown in California!
  • Strawberries came in second to blueberries in the USDA’s analysis of antioxidant capacity of 40 fruits and vegetables. They are also rich in dietary fiber and manganese, and contain more vitamin C than any other berry.

When do I plant strawberries?  Not now, NOVEMBER 1 to 10!  Yes, it’s that specific for winter chill at the perfect time!  They start producing runners now, but cut them off until early July!  Then let them grow, and cut off the new baby plants mid October for November planting.  Or, just let them grow to fill spots where, for one reason or another, a plant has gone missing, needs replacing, and/or another could fit in.  When those needs are taken care of, cut off the rest of the runners.  These runner plant babies will grow so fast you will be getting berries from them late summer and fall if you have everbearers/day neutral types!!

My plant isn’t producing….  

Variety
 – If it is an everbearer, day neutral, variety it will produce almost all year.  June/spring bearers put out a prolific batch in June, then it’s over.  No amount of care or feeding is going to make that plant have berries after June.  Sorry.  Best to get the varieties your local nursery carries.  Or talk with them about special ordering well in advance, so they can get the ones you want.
Temps – cold weather slows down pollinators.
Shaded – believe me, strawberries like all-day sun!  If you are going to tuck them in among other plants, be sure to put them on the sunny side!
Hungry – think about it!  A strawberry plant is often pumping out several berries at a time!  They are using up soil nutrition, so feed them!  Try a light solution of fish emulsion/kelp every other week over some sprinkled seabird guano or a well aged manure.  Give your strawberries a little fertilizer in the 0-10-10 proportions; that’s lots of phosphorus and potassium for strong roots and uptake of nutrients, blooms and fruits!
Water – don’t let them dry out, they will stop producing.  This month they tend to grow more leaves, send out runners.  Clip off the runners for now, so they don’t take your plant’s energy away from producing berries, unless you want more plants right away.
Mulching is good.  They love pine needle mulch, if you have some about, because they prefer slightly acidic soil.  Drape your berries over pine cones to keep them off the ground, out of the slug zone.
Age – First year plants and 3rd year plants don’t produce as well.

My berries are really tiny! 
Strawberry varieties vary from mammoth chocolatiers, to midget but mighty tasty alpines.  If it isn’t a variety issue, it may be diseased.  See below please.

Misshapen berries or split in two sections with a hole in the center 
Irregular watering  Your berry grows fast when it has water, then is restricted when it doesn’t….
Western Tarnished Plant Bugs,
feed on the flowers and developing surface seeds that stimulate growth causing misshapen berries, hard clusters of yellow seeds on the tip of the fruit.  Clean up debris.  Once you see this, you are too late to prevent it any further.  Bummer.  UC Davis IPM Integrated Pest Management on Lygus Hesperus.  Image of typical cat-faced berries.
Pollination Strawberry flowers are usually open and attractive to bees only a day or less.  Temperatures below 60F, low night temperatures, & high humidity result in inadequate pollination, low yields of small or misshapen fruit.  Strawberries require multiple pollination for perfect fruit formation. Generally, as the number of pollinator visits increases, there will be an increase in fruit set, number of seed per fruit, fruit shape, and fruit weight.  ABOUT BEES:  per NCSU ‘Bees rarely fly when the temperature is below 55°F. Flights seldom intensify until the temperature reaches 70°F. Wind speed beyond 15 miles per hour seriously slows bee activity. Cool, cloudy weather and threatening storms greatly reduce bee flights. In poor weather, bees foraging at more distant locations will remain in the hive, and only those that have been foraging nearby will be active.  Pumpkin, squash, and watermelon flowers normally open around daybreak and close by noon; whereas, cucumbers, strawberries, and muskmelons generally remain open the entire day.’  So if the weather isn’t right THE DAY OR MORNING your flower opens…..

Whole plant has yellow leaves.  The most common cause is nutrient deficiencies due to overwatering.  Overwatering causes poor root growth making it difficult to move enough water to the leaves during hot weather.  Lay back on watering; give your babies some Nitrogen –fish emulsion/kelp.

Strawberry Pests
Pecked   If birds are pecking your berries, put bird netting or a wire dome over them.

Rebecca & David Barker, Pilgrim Terrace Community Garden, Plot 41, staked the chicken wire in place, push it up to harvest, down to just the right height when done!

Holes in them, Chewed  Silvery slime trails are the giveaway!  Use the pine cones to drape your berries over to keep them off the ground.  Put down some Sluggo or the like, to kill off night-time nibblers, slugs, snails.  Harvest regularly before the berry gets soft and smelly, just before the buglets are attracted!  Those little black pointy worms?  I’m trying to find out what they are.  If you know, let me know, ok?!
Uprooted  Sad to say, that sounds like ‘possums, raccoon, or skunk.  They are looking for your earth worms or grubs.  Just like bunnies, these critters won’t jump a low barrier.  They just go around it.  So install a foot tall perimeter of wire pieces, black plastic plant flats, old trellis parts, whatever you have around, or go get something that looks good to you so you will be happy.  Relocating the critters is a good choice because, they do have children, that have children, that…

Strawberry Diseases  StrawberryPlants.org for full list of diseases.  Here’s a link to the 3 Most common leaf diseases with images.

Angular Leaf Spot – exactly that.  Spotted leaves.  A cosmetic problem until it isn’t.  Your plant will produce, but it won’t thrive.  Spread by water, harvest before you water, water under the leaves, remove badly spotted leaves, don’t use them as mulch, wash your hands before going on to another plant.
Strawberry Blight – the fungus is often confused with angular leaf spot, overwinters in old leaves, remove them.  Remove old leaves from runner plants before setting.  All day sun, well-drained soil, in an area with circulation, equals less fungus.  For good air circulation, plant far enough apart, remove weeds, remove, replant and/or give away runner baby sets.  Plant resistant varieties for your area of your state.  Discussion of SoCal varieties.  When you buy new plants be sure they are certified from a disease-free nursery.  If you use a fungicide, spray the underside of leaves as well as the tops.

Successful SoCal varieties!

Chandler is the most widely commercially grown strawberry in California.  High yield, early producer, large southern berry.  It’s a June bearer, so if you want year round supply, this is not your berry.
Seascape is an ever-bearing, big day neutral, all year strawberry, harvests are more abundant in late spring. High yield, resistant to most diseases except leaf spot.  Reliable producer in fall, performs well in hot, dry climates.  Berry is bright red inside and out!
Oso Grande Another June bearer, high yield big berry, good in warm climates.

Eat your red  plump strawberries!  Fresh from your garden, strawberry Sundae, strawberry sauce, strawberry pie, cake, bread, strawberry ice cream, whipped cream, yoghurt, cream cheese, cheesecake, strawberry shake, chocolate dipped, strawberry lemonade, strawberry Syrah, and, as always, the traditional, Strawberry Shortcake!!

Food Not Lawns is all about raising veggies not grass.  Studies show they both take about the same amount of water, but veggies pay back sustainably with fresh highly nutritious food on your table and no-food-miles or pollution.  Plus they make seeds for their next generation, adapting to your microclimate niche!  http://www.sbfoodnotlawns.org

  • Do I have to rip up my lawn?  You can do lasagna gardening/sheet composting right on top, start with cardboard/newspaper. 
  • Do I have to do a major portion of my lawn?  You can do any part you want, big or small, your call!
  • But I don’t want to do my front lawn.  You don’t have to!  It’s yours, do what makes you happy!  You only need 6 to 8 hours of sun to grow veggies, any space, corridor that has that, works.
  • Is it really hard work?  Using the lasagna/sheet composting method is no harder than gathering the materials to do it!  There is NO DIGGING!  And you don’t have to build raised beds.  Building soil on top of your lawn can make a lovely undulating landscape.  Frameless raised beds have plantable sloped sides!  
  • Is it ugly?   Could be, but how you do it is up to you!  It can be integrated along/among border landscaping plants, you don’t have to have raised beds at all.  If you want to though, you can make really attractive raised beds with beautiful materials, ie a lovely rock wall, terracing.  You can  cover an unsightly area like the edge under a south facing deck.  There are so many lovely options! 
  • I don’t want to wait months before I can plant!  You can plant the same day!  Just pull back a planting hole,  throw in compost, bought or made by you, plus any amendments you want, just like usual, and plant NOW!  No waiting at all!

                            Sheet Compost/Lasagna Garden Layers                           

Mulch or Tarp or not
Optional – Compost, Sprinkled Soil
Repeat layers until 18” to 2’ deep
Greens – Garden chop & drop
Browns – twice as deep as greens
Greens/Wet – kitchen veggie scraps, garden trimmings, grass, manure
Browns/Dry – leaves, straw for air circulation, alfalfa for Nitrogen
Well wetted Cardboard/Newspaper
Existing surface – Lawn

Wet green layers go above dry browns so the juicy decomposing stuff seeps down, keeping the brown stuff moist!  Straw is good in a brown/dry layer because air can pass through it, keeping the pile aerated!  Throw in some red wriggler worms to work the pile, make castings!  Maybe toss in some soil to ‘innoculate’ the pile with soil organisms.

Don’t worry overmuch about exactness of ingredients in your layers as you chop and drop greens from your garden/yard.  In fact, you can mix them up!  But do put in manures for Nitrogen (N).  Decomposing plants use N to decompose, so add a little so your growing plants will have an adequate supply.

If you can, make your pile at least 18” high; it is going to sink down as it decomposes.  Thinner layers, or layers that have been mixed, and smaller pieces, decompose faster.

If you like, cover the whole pile with some pretty mulch when you are done!  Or tarp it to keep things moist until ready for use.

When you plant, especially in ‘new’ soil, sprinkle the roots of your transplants with mycorrhizal fungi!  The fungi make micro filaments throughout your soil that increase your plants’ uptake of minerals, especially phosphorus that builds strong roots and increases blooming, fruiting!

Anybody can lasagna garden/sheet compost in any garden, any part of a garden, any or all the time!  It’s a time honored soil building/restoration technique!  Happy planting!

Rainy Day Harvesting!

Anticipate! 

Fertilize before a rain so the fertilizer will soak in.
Take the cover off your compost to let it get wet.
Tie or stake plants that may topple from wind or weight.
Set up to harvest rainwater for later use! 
Make raised beds, mounds, to help with drainage issues.
Mulch to keep soil from splashing up on your plants, keeping your harvest clean, holding water in place to soak in, and keep soil from eroding.
Make ‘permanent’ pathways with boards, stepping stones, straw bedding, so you won’t be compacting your planting area soil when it is wet or dry!
Plant for air circulation so foliage dries quickly.  Plants too closely spaced, make a warmer micro environment, tend to get mildew easier.
Choose mildew resistant plants! 
Drench your young plants with a mix of a heaping tablespoon of baking soda, a 1/4 cup of nonfat (so it won’t rot and stink) powdered milk in a large watering can of water for mildew prevention and abatement.  It works for certain other diseases as well!
Water less frequently and at ground level, not overhead.

During a rainy period….

If you didn’t before, get out there in your rain gear and add some manure or fertilizer!  Great excuse to play in the rain!
Check frequently to see how your plants are doing.  Secure any tall plants, trellises that need it.
If a plant is too low and in standing water, raise it.  Put your shovel deep under it, put some filler soil underneath the shovel!  
Add more mulch if it has shifted or wasn’t quite deep enough to keep mud spatter from your plants.
Be sure your wormbox worms are not doing the backstroke!
Rebuild any drainage channel that has weakened, clear if clogged.
Make sure all your rain harvest system is working well.  Kudos to you for harvesting!
Practice arm-chair gardening!  Read garden books, magazines, browse web sites, buy some seeds from mail-order catalogs, design your new garden layout!
Get some seeds, soilless potting mix, gather containers with, or make, drainage holes.  Start some seeds!
If the rain is prolonged, uh, do an aphid, snail and slug check as frequently as you can.  Sluggo works on snails  and slugs even when it is wet.  Hard to believe, but, yes, it does.
If the rain is prolonged, do harvest your fresh and crunchy produce!  Lettuces will flourish!  Check on fast maturing broccoli and cauliflower heads to cut at peak maturity!  Gather your luscious strawberries.  Keep your peas picked to keep them coming!

After the rain!  YES! 

Do some thinning for air circulation as makes sense.  Often there is a growth spurt, and you can see where thinning is needed.
Repair areas where soil has washed away exposing roots.  Put some mulch on.
It’s often warmer after a rain, and it is the warmth that mildew loves!   Drench mildew susceptible plants with your mildew mix immediately, early in the day so your plants can dry.  If you prune mildewed areas off, remove those prunings, wash your hands and pruners before you go on to other plants.
Do what you do about snails and slugs.  Keep checking for aphids – blast them away with water or remove infested leaves.
There is often more gopher activity after rain has softened the soil, so be ready! 
In later days, after the rain, harvest first, water second!  That’s the rule to keep from spreading diseases spread by moisture.

Enjoy the superlative rapid growth of your very happy plants!

What’s happening with my tomatoes?! 

Early BlightFusarium Wilt, Verticillium WiltLate Blight

Tomato – Healthy SunGold!

Tomato – Verticillium Wilt

This?!                                                 Or this?

This is bar none, the most common summer question I get asked! Potatoes, tomatoes, and the various forms of lettuce are the top three favorite vegetables in the US, so you can see why this is THE question!  Since fungi spread as simply as by the wind, I will be campaigning for more tomato plant care, starting with what people can do now to keep the fungi from overwintering, then in the spring to lessen its chances.  There are more things that can be done than I knew!  Read on! About Fungi   To emphasize the potency of these fungi:  Late Blight of potatoes and tomatoes, the disease that was responsible for the Irish potato famine in the mid-nineteenth century, is caused by the fungus-like oomycete pathogen Phytophthora infestans. It can infect and destroy the leaves, stems, fruits, and tubers of potato and tomato plants. Before the disease appeared in Ireland it caused a devastating epidemic in the early 1840s in the northeastern United States. Not only do the fungi feed on your tomato plants, but take a look at your potatoes, peppers, eggplant, cucumbers and beans!  See those yellowing leaves?  Remove and dispose of them ASAP!  That removes zillions of spores so they can’t spread.  The wilts and blights also affect trees!  Sadly, not only do your plants look depressing, production is zilch, they die an unnatural death.  Remove, replace.  Be happy. How do fungi work?  Spores are spread by rain/watering splash, insects, and wind, and through our hands and tools (wash your hands and tools after handling infected plants) and through these mediums, can travel distances.  That’s why it is so important, in our community garden, to tend our plants, so our neighbors’ plants won’t also be infected.  Educate your plot neighbors, better yet, send this to them!  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 on debris and weeds. What they look like on your plant: 

Tomato – Early Blight

14 Fungi Preventions!

Cultural control practices alone won’t prevent disease during seasons with wet, cool weather. However, the following measures will improve your chances of raising a successful crop.

Things you can still do this season!** Things you can do now to prepare for next season!**
  1. Buy toms that are tagged VFN, or just VF – that’s Verticillium Wilt and Fusarium resistant or tolerant. Varieties that set fruit early, at lower temps, are Early Girl Improved, Fourth of July, Enchantment. Excellent resistant varieties are Champion, Husky Red, Better Boy, Ace Hybrid, Celebrity.  
  2. Plant only healthy-appearing tomato transplants. Check to make sure plants are free of dark lesions on leaves or stems. If starting transplants from seed, air-dry freshly harvested seed at least 3 days.  
  3. 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 plants may not win the battle.  Do not let volunteers grow, even on compost piles, cute as they are. Infected tomato refuse should be put in the trash.  
  4. **Create a soil barrier, mulch!  You can layer newspaper/cardboard covered with mulch or grass clippings.  Anything organic, as you wish.  One to 2 inches of straw is easy to lay on.  You want to create a splash barrier. Seal the soil and you reduce the chances of spores finding your plant. Bottom line, you don’t want your soil to contact your plant.  
  5. **Avoid wetting foliage when watering, especially in late afternoon and evening. Water at the ground!  Watering the leaves creates a humid micro climate; the fungus produces spores. Dry leaves. Dry leaves. Dry leaves.  No moisture, no spores.  
  6. **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 to 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.  
  7. **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.  
  8. **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.  Your tomatoes will get plenty of water from their deeper roots.  
  9. **Remove bottom leaves, again, no touching (the ground), and prune your plants.  Barbara Pleasant at Mother Earth News says, ‘When the lowest leaves are removed just as the first leaf spots appear, you also remove millions (zillions) of spores. And, because the bases of pruned plants dry quickly, the spread of the disease is slowed because early blight fungi need damp leaves in order to germinate and grow.’  Create an 18 to 24 inch barrier gap or safe space between your garden soil or mulch and the first leaves of the tomato plant. If the spores can’t splash upwards and reach the leaves, they can’t take hold. The stem usually isn’t a place for the spores, though it can be. Best is to remove the bottom leaves before the spores start!  If you have large plants, you might consider cutting off some branches to let the sun and wind blow through the main body of your tomato plant.  But, some gardeners don’t recommend pruning or snipping the suckers, the mini branches formed between the trunk and branches, because spores can enter through these cuts.  If you decide to prune, the less cuts the better.  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.  
  10. **Remove infected leaves immediately. A leaf should be completely green. Look for brown spots or yellow spots or distress. Remove leaves and prune when it is dry and sunny, not windy. Wash your tools and hands often.  
  11. After the tomatoes set, add some nitrogen. A healthy plant tends to fight off the spores. 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.  
  12. **Rotate your crop if possible. Because fungi also affect other plants, rotation in small gardens isn’t practical or even possible. But if you have the room, move your tomatoes to areas that are fungi free.  
  13. ****At the end of the season remove, don’t compost, all infected debris and surrounding debris. Pull all the weeds because spores can over winter on weed hosts. You want to reduce the number of spores laying in wait.  
  14. **The spores aren’t super spores. During our winter season, turn your soil about 10 inches, burying the spores helps remove them, and it also exposes snail eggs to die.

Preventive Foliar Mix that does wonders! 

Apply every 2 to 3 weeks, so new growth will be covered.  Wet under and over the 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

Water your plants with an aspirin?!  Salicylic acid, in aspirin, triggers a defense response in tomatoes and other plants as well! Adapted from eHow:  The main benefit of aspirin in planting involves aspirin’s ability to fend off potential plant diseases.

  1. Purchase regular strength aspirin. The brand does not matter; purchase the cheapest brand that is available.
  2. Mix together one aspirin with one gallon of water. Combine the ingredients well, so that the aspirin is distributed evenly throughout the liquid.
  3. Add a dash of mild liquid soap to the mixture. This is used as a way to help the aspirin water stick better to the tomato plants. Once the soap is added, attach a spray nozzle to the gallon jug and it is ready to use.
  4. Spray the tomatoes when you first set them in the ground. Aspirin sprayed directly on seeds improves germination, on plants it stimulates the growing process. There is no need to soak the area. A light and gentle spray will suffice.
  5. Continue to spray the aspirin mixture on the tomato plants every 2 to 3 weeks. You are going to notice that the plants stay healthier and attract fewer insects.

Per a comment by Leroy Cheuvront at Heavy Petal blog:  I have had the blight and have stopped it from destroying my tomato plants. All you have to do is mix 2 ounces of bleach to a gallon of water and drown the plant from top to bottom, it will not kill the plant. I do it every seven days and the blight has not returned.  — June 18, 2010.  It sounds scary, but I bet it works! I would test this principle on ONE plant to be sure it is safe to use. Solarization  In the past ten years, some enterprising Israelis came up with solarizing. Moist soil is covered with transparent plastic film for four to six/eight weeks in the summer.  It takes that long to heat the soil to a temperature and depth that will kill harmful fungi, bacteria, nematodes, weeds, and certain insects in the soil. Solarization can be a useful soil disinfestation method in regions with full sun and high temperatures, but it is not effective where lower temperatures, clouds, or fog limit soil heating. Solarization stimulates the release of nutrients from organic matter present in the soil.

Solarization

Solarization also kills grass by heating up the soil when daily temperatures exceed 80°F. Weed eat or mow the area as short as possible. Moisten the soil and cover the area in clear plastic for 10-14 days, until the grass is dead.     Although cloudy weather will slow things down by cooling the soil under the film, a few weeks of sunshine will improve your soil dramatically, easily, and inexpensively. If you live in an area with cool or cloudy summers, or if you just don’t want to wait all season, you can speed up the process by adding a second sheet of plastic. Using the hoops commonly used to elevate row covers or bird netting, raise the second sheet of plastic over the ground-level sheet. The airspace between acts as a temperature buffer zone during cloudy weather and the combination of the two sheets of plastic serves to raise the soil temperature an additional 6 degrees.  The goal is to raise and maintain temperatures in the top 6 inches of soil to a level between 110 to 125 degrees F.  After several days of sunshine, soil temperatures rise to as high as 140 degrees at the surface and well over 100 degrees as far down as 18 inches.
