Are you having fun?! Does your garden make you this happy?! PLANT MORE!
Coolish April temps delayed bell pepper plantings…until we had three quite hot days of 80-90s temps at the very last of April then a set of warm enough days! Night temps are now faithfully above 55°. Sweet peppers need nighttime temps that are steadily above 55°F, some say 60, and soil temps above 65°F. April 28 8 AM soil temps at Rancheria Community Garden were 65 to 70, from wet to dry plots, in the sun. Get out your soil thermometer and check the soil temp where you garden! If planted too soon, sometimes plants miss their natural sequence of production, and never produce. Best to replant if you suspect this is happening. See Best Planting Temps Per Veggie!
May, June Planting Timing
MAY is time for cantaloupe, sweet bell 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, for warmer drier soil, 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. 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.
Long beans are spectacular and love heat. Late May, June is the best time to start them. They grow quickly from seed. They will last longer than other beans, hitting their stride toward the end of summer. Certain varieties of them don’t get mildew either! Their unique flavor keeps your table interesting.
While we are waiting for the right temps, do soil preps that are still needed. Weed out plants that won’t help your summer lovers. Make your soil fluffy with water holding compost, only 5 to 10%, while also adding tasty well aged manure! Add worm castings to areas that will be seeded. Castings improve germination, germination is sooner, seedlings healthier!
Plant another round of your favorite heat lovers! Might be eggplant, limas, peppers and pumpkins! Transplant or seed different varieties of beans, cucumbers, eggplant, melons, peppers, squash, and tomatoes than you planted before! Sow and/or transplant asparagus, beets, carrots, celery, chard, herbs, kale, kohlrabi, leeks, heat-tolerant leaf lettuce, summer-maturing onions, parsley, peanuts, rhubarb and spinach! Add white potatoes and radish with zucchini, radishes with cukes to repel cuke beetles, and with eggplant to repel flea beetles. Add fillers and littles under bigger plants as living mulch! Put some color in your choices! Plant RED table onions, fancy lettuces! Tips for super Successful Transplanting!
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 the heat doesn’t bother! Heat tolerant tomatoes keep right on producing when temps get up to and above 85! Rattlesnake beans are a winner! They produce in up to 100 degree weather! They have a slightly nutty flavor. You do have to keep watch and pick almost daily because they get long and plump quickly – and are still tender!
Problem temps for tomatoes:
High daytime temperatures (above 85 F)
High Nighttime Temperatures (above 70 F)
Low Nighttime Temperatures (below 55 F)
Check out this nifty page of heat tolerant tomato varieties at Bonnie Plants! If your plant is not heat tolerant, wait. When things cool down, it will start making flowers and setting fruit again. See also Tomatoes are the Fireworks of Your Summer Garden!
Time for heat and leaf tip burn resistant, bolt-resistant lettuces of all kinds! Sierra, Nevada, Jericho, Black Seeded Simpson are some. Green Star wins the beauty award!
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, a low water table area, 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! They are currently open by appt! See Special Planting and growing tips for your Tomatoes and Cucumbers! If you are interested in the Indigo family of tomatoes, in the Santa Barbara area, Terra Sol and La Sumida both have them this year!
Once you have these strong varieties installed particular maintenance will keep them healthy longer.
- Remove any leaves that will touch the ground if weighted with rain, dew or by watering.
- Remove infected leaves the curl the length of the leaf or get brown spots.
- Lay down a loose 1″ deep straw mulch blanket to allow air circulation and the soil to dry. No friendly fungi habitat. The most important purpose of this mulch is to keep your plant’s leaves from being water splashed or in contact with soil, which is the main way they get fungi/blight diseases.
- When the straw gets flat and tired, remove (don’t compost) and replace.
Flowers or veggies that are great companion plants for your tomatoes!
Companion Plants! Always be thinking what goes near, around, under, with, what enhances your plant’s growth and protects it from damaging insects and diseases, or feeds your soil! Keep the biodiversity rolling! Plant pest deterring plants first so they will be up and working when you put in your seeds or transplants! If you forget, you can always add your companions later.
- Alyssum is a great old fashioned pretty border plant, an understory living mulch. And WHITE Alyssum repels the cabbage butterfly.
- Basil repels several unwanted insects, is great near tomatoes but not in the basin with the tom. The tom needs less water. Plant the Basil beside the tom basin. The deeper tomato roots will get water used to water the Basil!
- 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.
- WHITE Potatoes with Zucchini & Cukes 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! Plant with tomatoes and asparagus.
- Chamomile is a love! Pretty, great tea, known as the “plant doctor,” chamomile has been known to revive and revitalize plants growing near it. That’s especially good to know for plants that are susceptible to diseases. Plant it by plants that are wilts susceptible, like your tomatoes & cucumbers .
- Cosmos is for pollinators! More at SFGate
- Marigolds are brilliant and called the workhorse of pest deterrents!
- Lettuce and carrots make a great understory below larger plants like peppers, eggplant. They act as living mulch! Leave a little open space to lightly dig in some compost or manure later in the season. If you already have enough lettuce and carrots, scatter a living mulch, soil feeding legume seed mix under those plants. At the end of the season you can turn it all under – aka Green Manure. Or remove the larger plants, open up spots in the living mulch and put in winter/summer plants! See much more – Living Mulch/Green Manure!
Now is the time watering becomes critical!
SEEDS need to be kept moist. If they dry they die and you either replant or if you don’t have time, just go get transplants. Of course, the advantage of seeds is you have a lot more variety choices than what you can get at the nursery if you aren’t too late in the season to get them if you don’t have any more… Always purchase extra seed for accidents and incidents, ie birds or insects.
TRANSPLANTS need to be kept moist the first few days until they acclimate to their new home. Gentle watering. I water once, then go back and do the whole area again, giving the first watering a chance to soak down. Flooding is not necessarily a good choice. Soil needs oxygen, and plants can literally drown.
THE SCHEDULE What schedule, LOL?! It all depends on the weather. In our area there are hot days, cool days, overcast days, not often windy. But very hot and windy together might mean watering twice a day, whereas cool and overcast might mean an inch of water a week could be just fine. Water beans, cukes, lettuces and short rooted varieties of strawberries more frequently – 2 to 3 times a week, daily in very hot or windy weather. Poke your finger in the ground after rains to see just how deep the water soaked in. Use your shovel and wedge a spot open to see if the soil is moist deeper.
Most plants need to be kept moist. Kept moist. Dry crusty soil keeps your soil from breathing. Compost, mulch and planting living mulch are all good answers. Compost has excellent water holding capacity. Work it in gently around the dripline of your plant so as to damage as few roots as possible. Maybe only do one or two sides of your plants so all the feeder roots are not destroyed. It will set your production back if your plant has to regrow them. Mulch only if your soil temps are up to par. Otherwise, wait, so the mulch doesn’t keep your soil cool.
Living mulch has two advantages over dead mulch like bark or straw. 1) Living mulch can be an edible understory of small plants I call Littles. Their shade keeps the soil cool and moist. On balance they need water too, so you might use a wee bit of more water, but you also get 2 crops in the same space! 2) Living mulch can be soil feeding legumes under your bigger plants. They too shade and keep your soil moist and looser. In Santa Barbara a good choice can be White Clover. Get bulk seed at Island Seed & Feed.
The plant that does well with straw is cucumbers! It keeps the fruits clean and soil free, and, drum roll, might slow cucumber beetle movement from one plant to another! Plus, it is great shelter for wolf spiders, daddy long legs and other predators. The more spidies the more healthy your garden!
The first plant you mulch is any over summering Brassica – broccoli, kale. They like cool soil, so pile it on good and deep, 4 to 6 inches, or plant a dense understory of living mulch that won’t be harvested, or if you do harvest, cover that spot with straw ASAP! Peppers are quite the reverse, the last plants you mulch. They like soil temps above 65. Mulch keeps the soil cooler, so use your soil thermometer to see if the mulch is cooling it too much for your peppers.
Pumpkins, melons and winter squash may do much better with NO mulch at all! They all need heat. Rather than trellis these crops, up in the air is cooler, leave them on the ground where it’s good and hot. You might even put in a straw bale windbreak for them if you have the room. Put the bales on their sides in a U shape that opens to the hottest time of day sun! Put reflective pie tins under fruits, or mulch under the fruits to keep them clean and above ground insect level.
Furrows and basins are perfect for water capture, just like the SW indigenous peoples did with their waffle gardens. The water collects at the bottom, the drying wind goes over the berms. You can raise your tomato and cucumber basins onto the tops of your mounds so there is better drainage and your soil dries somewhat. For plants that are not wilt fungi vulnerable, dig your basins and furrows down, less work because no berms are needed too be made. Let the normal soil level be the ‘berm’ for the wind to blow over.
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. The exception is winter plants in the Brassica family – Broccoli, Kales. They don’t interact with mycorrhiza.
Save water by using a long water wand to water under your plants, not the foliage. Use one with different settings so you use only what your plant needs, and an easy to use shut off valve so you use water only when you need to.
Garlic, bulb onions, and shallots naturally begin to dry this month. When the foliage begins to dry it’s time to STOP watering them. Dry outer layers needed for long storage will form on the bulbs. When about half of the foliage slumps to the ground, bend the rest to initiate this maturing. The bulbs will be ready for harvest when the foliage is thoroughly dry and crisp.
Natural Disease & Pest Prevention!
- 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. Locally, save seeds from plants that do the best with the heat and share some of those seeds at the Seed Swap and with other gardeners.
- 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, more understories and intermingling. 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.
- Make top notch soil!
- In planting holes
– Add worm castings for your plants’ excellent health. 25% is best; 10% will do if that’s all you got.
– Add a tad more tasty properly aged manure mixes where manure lovers like peppers will be planted.
– Add non-fat powdered milk for immediate immune system support at planting time
– Put in a finely ground bone meal for 2 months later uptake when your plant gets to flowering time.
– Add Jamaican guano high in P, Phosphorus, at planting time. It helps your plants continue to bloom LATE in the season! Its NPK ratio is 1-10-0.2, takes 4 months to become available to your plants. Other guanos don’t have this particular NPK ratio.
– Add an eency tad of coffee grounds (a 1/2 of a %) if you have wilts in your soil
– Sprinkle mycorrhizae fungi directly on transplant roots, all but Brassicas, at planting time to increase their uptake of nutrients and water.
– Use acidic compost in strawberry patches and work in a little where you will be planting celery and string beans. - 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.
- 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! Some sites say with good starting soil you shouldn’t need to amend during the season. Your plants will tell you if they do need more food. Maybe your soil wasn’t perfect. Maybe your plant has phenomenal production and gotten hungry. When production slows down, decide if you want more. Feed your plant a bit and see what happens.
- 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.
- Harvest promptly. Insects and diseases can signal when plants/fruits are softening and losing strength as they age. Insects are nature’s cleaner uppers, and they and disease organisms are hungry! If leaves are yellowing or not looking up to par, remove them. Whiteflies are attracted to yellow.
- Prevention A frustrating typical spring disease is Powdery mildew. It’s common on late peas, Curly Leaf kales, broccoli, cucumbers and zucchini. 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.
The usual May culprits!
- Cucumber Beetles get in cucumber, squash and melon blossoms. They aren’t picky. They are yellow greenish with black stripes or dots about the size and shape of a Ladybug. They are cute but are the very worst garden pest. They carry bacterial diseases and viruses from plant to plant, such as bacterial wilt and mosaic virus, deadly to cukes. Radish repels them, is a champion plant, a hero of the garden! Plant enough radish for you to eat and to let others just grow, be there permanently or at least until the beetles are done, gone. IPM data Straw mulch recommended.
- Squash Bugs like your Zucchini and other squash, cucumber and melons. Plant radish and WHITE potatoes amongst them to repel the bugs. Let some of the radish grow full height, eat the others as usual! You will get three crops instead of just one! IPM info
- Flea Beetles look like large black fleas and do hop mightily! They seem harmless enough, make tiny little holes in the leaves of eggplant, potatoes, arugula. But, those tiny holes add up. As the beetles suck out the juice of your plant they disrupt your plant’s flow of nutrients, open the leaves to disease, your plant is in a constant state of recovery, there is little production. Your plant looks dryish, lacks vitality. The trap plant for them, one that they like best, is radish! Thank goodness radish grow fast! Better yet, plant it ahead of time, or ASAP when you put seeds and transplants in. IPM notes
- Whiteflies do the honeydew thing like aphids do, leaving a nasty sticky black sooty mold or white fibers all over your plant’s leaves. The honeydew attracts ants, which interfere with the activities of Whitefly natural enemies. They are hard to get rid of, so keep a close watch on the undersides of leaves, especially if you see little white insects flying away when you jostle your plant. Whiteflies develop rapidly in warm weather, in many parts of California, and they breed all year. Prevent dusty conditions. Keep ants out of your plants. Hose them away immediately. Calendula is a trap plant for whiteflies. See more
Now is the time to be thinking of soil prep for the future! Gather and dry good wood now for trial Hugelkultur composting at the end of summer, early fall! Woods that work best are alders, apple, aspen, birch, cottonwood, maple, oak, poplar, willow (make sure it is dead or it will sprout). Hugelkultur can be a simple huge pile or an elegant graceful design like this one. Could be right in your front yard! See more!
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. Comfrey, mint and oregano are invasive. Remove the bottom of a 5 gal container, sink it where you want your plant and plant in it. That contains the roots where you want them. Mint can jump ship, so keep a constant eye on it! Be mindful where you plant your herbs… 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, soft herbs like 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 take to the seed swap! Grow beauty – cosmos, marigold, white sweet alyssum – all benefit your garden in their own way! See Stripes of Wildflowers! Here are some special considerations – Courting Solitary Bees!

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.
