May is for Melons! Goldfarb & Page-Mann Regional Fruition Seeds - Juicy Watermelon!

Matthew Goldfarb & Petra Page-Mann of Fruition Seeds, Canandaigua NY

We have had crazy April weather in Santa Barbara! Night temps were low for the longest, then we have had HOT days followed by more cool evenings and now we are back to hot. My kale and cabbages bolted. Early varieties of tomatoes have done well and corn and hot pepper plants, but few have risked planting bell peppers yet. They like warm evenings and soil.

Recent night air temps have still been in the late 40s, up to as much as 58. Soil temps in the sun are now 60 to 68. Peppers especially need warmer temps, nighttime temps above 55°F, some say 60, 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!

May is generally the super month for more heat lovers, but many here haven’t planted their first rounds yet. If your area has been behaving, space permitting, do plant your second rounds this month! Start some more, different varieties of tomatoes, peppers, eggplant! The special planting treat of May is CANTALOUPES!

Start from seeds, transplants or both! Add different varieties with different maturity dates for a steady supply, a palate pleasing assortment! Some people just remember when they planted what. Others make an ID plant tag with the plant date and name on it and the # of days to maturity. A quick glance will tell you if that set of plants is ready for another round to be planted. Or, just jot it in your calendar so you be sure to plant another round in 6 to 8 weeks.

If seeds and tending seedlings aren’t for you, transplants are fine! Eggplant, limas, all melons, all peppers, pumpkins and squash! Many wait until even June to plant tomatoes to avoid fungal problems, but if your garden is fungus free, plant away! Ideally you would wait until the soil has warmed to 70°F before sowing squash and melon seeds, but if you can’t wait, and who can?, get nursery transplants and pop them in the ground!

Some gardeners do wait until JUNE to plant southern heat lover okra. 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.

Right now, in addition to the plants listed above, sow and/or transplant more asparagus, beets, carrots, celery, chard, corn, herbs, kale, kohlrabi, leeks, heat-tolerant leaf lettuce, parsley, peanuts, white potatoes repel squash bugs, radishes (with cukes to repel cuke beetles, and with eggplant, potatoes and arugula to repel flea beetles), and spinach.

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

See last month’s chat on Tomato and Cucumber specifics, especially if your soil has Fusarium and Verticillium wilts as ours does at Pilgrim Terrace and Rancheria Community Gardens. Mainly, keep those babies’ leaves off the ground! Remove lower leaves, get them UP in a cage or trellis and lay down a loose 1″ deep straw mulch blanket. Too much straw keeps the soil moist, which is good for some plants, not for others. Under maters and cukes, we want some air circulation and a bit of soil drying. The main purpose of 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.

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 that produce all season long rather than getting determinates that need start up time every time you replant, that need water during no production periods. If you are canning, then by all means, get determinates. 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! 

With our warming temp trends, get bolt resistant/slow bolt varieties, and especially heat and drought tolerant varieties. Heat tolerant tomatoes and beans (Rattlesnake) keep right on producing when temps get up to and above 85.

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 varieties at Bonnie Plant! If your plant is not heat tolerant, wait. When things cool down, it will start making flowers and setting fruit again.

Companion planting is more than saying Howdy! Certain combos enhance growth, others repel pests, some invite beneficial insects! Strengthen your garden! 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! It is thought to repel white flies, mosquitoes, tomato hornworms, aphids, houseflies, and asparagus beetles. Smells great and tastes great!
  • Beans, Cukes, Dill, Radish Combo! Cukes and Beans are great on the trellis, one high, one low. Dill goes with your pickling cukes. Radishes to deter Cucumber beetles.
  • WHITE Potatoes with Zucchini to repel squash bugs.
  • Radish with eggplant, cukes & zukes act 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!

Put in ‘licious fast growers like lettuce, beets, turnips, arugula, in space being held for subsequent plantings. To use your space super productively, put these veggies on the sunny sides under any large plants. If needed, remove lower leaves that would shade out the ‘littles.’ If you anticipate unusually hot summer weather, grow the littles on the east side of larger plants to protect them from the afternoon sun.

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.

Watering Tips

  • In these drought times, water before 10:30 AM if at all possible. The earlier the better. Make your basins large enough to accommodate your plants water needs out to the dripline. Water at the base of your plant. If your plants are dusty, you are near a road or there has been a wind, give them a bath. Dusty plants are habitat for White Flies. Keep a lookout, and hose away ants.
  • The general rule of thumb is 1 inch per week. In very hot or windy weather, water as needed, even as much as twice a day!
  • 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. They are all workhorses producing fast and repeatedly, cukes making a watery fruit even. Lettuces need to put on growth fast to stay sweet.
  • Garlic, bulb onions, and shallots naturally begin to dry this month. When the foliage begins to dry it’s time to stop watering. 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.
  • Please always be building compost and adding it, especially near short rooted plants and plants that like being moist. Compost increases your soil’s water holding capacity.
  • Good quality organic MULCH feeds your soil, keeps your soil cooler, moister, less water needed and prevents light germinating seeds from starting – less weeds!
  • Pat on Mycorrhiza fungi right on the roots of all your transplants except Brassicas, 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.
  • If you garden in a windy area, put up porous windbreaks to slow soil drying, and you will have less dusty conditions that bring White Flies.
  • Use a water device with an easy to use shut off valve.

It’s Mulch time! Compost is fine and fluffyish, intended to feed your plants, goes IN your soil. Mulch has larger pieces, and is meant to cover the surface to keep your soil cooler and moist. If it is put in the soil, larger pieces use your soil Nitrogen as they break down, depleting the Nitrogen your plants need. Straw is probably the cheapest and cleanest organic mulch. Some don’t like it that you do have to pull grasses that come up. Others don’t mind at all, they just tuck it under the mulch and it feeds the soil too! Otherwise, get good quality bags of undyed mulch.

  • If you are an organic gardener, it’s up to you if you choose to use City mulches. They are made from street side green waste recycle containers that can include diseased plants, non organic chemical treatment residues, toxic plastics etc.
  • Living mulch is when you plant an area densely enough that the leaves of the plants shade your soil and keep it moist. Lettuce does a good job. But also know that makes a moist habitat for slugs and snails, so put down some organic bait two or three times to kill off the generations. Get the store brand of Sluggo. It’s non toxic to pets and kids!
  • Peppers are 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.
  • Any Brassicas – broccoli, kale – you are over summering need good deep mulch, 4 to 6 inches. They like cool soil.

Natural Disease & Pest Prevention!

Choosing excellent and appropriate plant varieties, using companion plants in wise combinations, making super soil, regularly applying prevention formulas more details and all the recipes, sidedressing and keeping up on maintenance are the things that keep your plants in top form! They will be less likely to have diseases, but pests adore tasty healthy plants just like we do, as well as them cleaning up plants that are weak or on their way out. Often when you plants are being munched, you have missed the prime harvest time. See more in the April Newsletter

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
  • 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 ASAP when you put seeds and transplants in. IPM notes
  • Squash Bugs like your Zucchini and other squash, cucumber and melons. Plant WHITE potatoes amongst them to repel the bugs. You will get two crops instead of just one! IPM info
  • Whiteflies do the honeydew thing like aphids, 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, they breed all year. Prevent dusty conditions. Keep ants out of your plants. Hose them away immediately. See more

Please 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 planters put chives where you need to repel Bagrada Bugs, 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!

The first gatherings of the garden in May of salads, radishes and herbs made me feel like a mother about her baby – how could anything so beautiful be mine. And this emotion of wonder filled me for each vegetable as it was gathered every year. There is nothing that is comparable to it, as satisfactory or as thrilling, as gathering the vegetables one has grown.

  • Heat tolerant
    x
    Peppers are a Solanacea like tomatoes, and like tomatoes they produce poorly during high temperatures. Banana, ‘Gypsy’ and pimento produce very well, despite the heat. Jessie Keith says ‘super spicy classic jalapeno ‘Tula’, wonderfully flavorful pasilla-type pepper ‘Holy Molé’ (2007 AAS Winner), and classic spicy sweet red bell pepper ‘Mexibell’ (1988 AAS Winner). Of the sweet bell peppers nothing beats the tough, [thick walled] disease-resistant ‘Orange Blaze’ (2011 AAS Winner) and its crisp, bright orange peppers.’ Heirloom Olympus (65 days green, 85 days red) has large bell peppers on medium-sized plants with good leaf cover. They are high-yielding plants, are heat tolerant and can set fruit under a wide range of conditions. MG Seed Stock. If you planted varieties that are more heat susceptible, put up a shade cloth cover. Depending on the density you select, shade cloth can lower the temperature by approximately 5-15 degrees. If you live in a hot area, bell pepper transplants can be planted in August for fall production when the weather cools down.
    x
  • Drought tolerant Look for the terms drought tolerant, drought resistant, dry farmed when searching for the best variety for your garden. It’s important to know that drought tolerant doesn’t necessarily mean heat tolerant and vice versa, so stay alert if you need both. When you are buying seeds, consider the location of the seed company. Perhaps local seed houses will understand your needs best. Check in with local farmers to see which varieties they are growing, remembering that some of their standards are different than a home gardener.For those of you in water critical areas, one way to help the situation is to pick pepper varieties with fewer days to maturity. You get peppers, you can freeze some, your plants are done before the highest heat and driest times.The UC Sonoma County list is short. Only two varieties, Jupiter Red Bell and Ordoño.

Location! If you have a short summer season or are cooler and coastal perhaps, choose earlier smaller fruited varieties than ones that need a long hot summer to fully mature and if necessary change color too.

Planting

Peppers are Temp Particular! Peppers grow best in daytime air temperatures 65° to 85°F. Transplant when night time temperatures stay above 50 degrees, 55 is better. Below that plants grow very slowly, have yellowish, puckered leaves, and look sickly, often don’t recover. Night temps between 60° and 70° are best. The ideal temperature for peppers is a daytime temperature around 75°F and a nighttime temperature around 62°F.

At soil temperatures above 65 degrees, pepper growth accelerates. If either the soil or air temperature is much below 55 degrees, blossoms of transplants may drop off. The plants may survive and more blossoms will appear. But it is more likely plants will become stunted and never recover. If your plant is puny and showing no growth, best to compost it and replant when it is warmer.

  • Nighttime temperatures below 60 F or above 75 F can reduce fruit set. In daytime temperatures greater than 85°F, peppers may drop their blossoms although set fruit will ripen. When daytime temps reach 90 F and above, and stay there, just like with tomatoes, the blossoms seldom set fruit. Not to worry. Just give them some time after temps are lower.
  • Plumping up! Gardeners in hot regions will need to be especially patient with big bells and sweet roasting peppers. Both of these tend to wait until the nights are longer and cooler in late summer before fruiting and plumping up. These folks may want to plant banana peppers or sweet non-bells, which will ripen in time to use with those bumper crops of tomatoes and basil. Peppers need time on the plant to absorb nutrients and water and plump up their flesh, so pack your patience.
  • Color Changes! Mother Earth News says: After reaching their maximum size, green peppers that are meant to turn red, will develop red pigments in 10 to 28 days, if daytime temperatures are between 65 degrees and 75 degrees. In southern regions where temperatures exceed that range, peppers turn yellowish and may acquire an off-color pallor that is not attractive. Below the optimum temperature range, color development slows dramatically; below 55 degrees, it stops completely. If soil temperatures drop below 68 degrees, pigment production declines and eventually ceases.

Peppers love sun, but a bit of shade is good for the fruit. I planted a Poblano between two big tomato plants. For awhile I thought it was a goner, shaded out, then, it just grew and grew! It got almost 4′ tall and produced like crazy and I gave giant peppers away!

Peppers need VERY RICH SOIL, are heavy feeders! Place compost for water holding capacity, worm castings, rotted manure under them when transplanting. Mix in Maxi Crop and Island Seed & Feed Landscape Mix. Sandy soils are preferred for the earliest plantings because they warm more rapidly in the spring. Heavier soils can be quite productive, provided they are well drained and irrigated with care.

Epsom Salts! Rather than in the soil, do foliar Epsom Salts! A cheap home remedy that can keep plants greener and bushier, enhance production of healthier fruit later in the season, and potentially help reduce blossom-end rot. You could apply 1 tablespoon of granules around each transplant, but research has shown a foliar spray of a solution of 1 tablespoon Epsom salts + a 1/2 teaspoon of liquid dish soap (Dawn) per gallon of water at transplanting, first flowering, and fruit set is more effective! As a foliar spray, Epsom salts can be taken up quickly by plants, otherwise, it is sometimes hard for the plant to get it out of the soil because of calcium competition.

Plant your peppers about a foot to 18″ apart.  A healthy pepper will get big and top heavy with fruit! It is wise to put small tomato cages over thick wall bell pepper varieties when you plant, to support the weight when they are heavy with fruit.

Though a perennial, they are very susceptible to freeze. With Bell peppers, I have heard a lot of people say their peppers overwintered and produced just fine the following year, but I have not seen that to be true at the community gardens. They are never as robust nor do they produce the big healthy fruits first year plants do. If you are one of the lucky ones, by all means, protect them when there are freezes.

Hot peppers are another story. They seem to do a lot better overwinter, depending on the variety, and I have seen them carry on wonderfully!

Care

Personal Mulch! Solanaceae, that’s peppers, tomatoes, eggplants, like mulch from their own leaf litter, so just let the leaves fall and accumulate. In hot summer weather your peppers will appreciate a heavy mulch. Several inches of straw or dried grass clippings will keep the soil cooler and reduce moisture evaporation. Continually moist ground is a necessity for peppers, as they, like tomatoes, suffer from blossom end rot, a physiological disease caused by a calcium deficiency. Most soils contain ample calcium, but the mineral relies on water to transport it to the plant’s root system. When the soil lacks moisture, the calcium can’t reach the plants and a tell-tale black leathery spot forms on the blossom end of developing fruit. Heavy Nitrogen fertilizer applications can also induce a transient calcium deficiency. I emphasize that you give your peppers plenty of compost for water holding capacity and keep them well mulched!

Peppers, have shallow roots, need even wateringKeep the soil moist, not soggy, to encourage root development and prevent blossom wilting and bitter-tasting peppers. Moisture stress during bloom can cause substantial reduction in fruit set.

Later on, however, as a friend from Farmers Market pointed out: ‘Red & yellow peppers are green peppers that have been ripe for a while. So you are asking an already ripe fruit to stay on a vine longer to change color. Too much water, and the pepper will start to turn brown and rot. So we switched to watering a LOT less frequently and the results have been outstanding.’

Sidedressing Peppers need fertilizer in small doses, a rich organic fertilizer when blooms appear. If you scratch in some compost, be careful not to damage their shallow roots. Liquid chicken manure is high in nitrogen and potassium for heavy feeders like peppers. Big, sweet peppers require a continual source of nutrition. The easiest way to fertilize them is to incorporate gradual-release fertilizer in the ground at planting. Fish-meal pellets, alfalfa pellets or cottonseed meal are all good organic choices. You also can foliar-feed plants every week or two with a fish/seaweed soluble fertilizer, spraying the tops and bottoms of leaves, or water the ground with the same mixture.

Replenish mulch as needed throughout summer! You might schedule a mulch check for them and all your plants once a month.

Annual or Perennial? Technically peppers are perennials, grow year after year – in the right climate. Some chiles overwinter well in Santa Barbara. Bell peppers are another story. Geographically, in Santa Barbara CA they are temp sensitive annuals! I’ve heard claims about them overwintering in the garden successfully, but I have yet to see it. If you like to do it, better to pot your pepper before any frosts and take it indoors by a sunny window or into your fine greenhouse! You have a couple choices. Prune it ruthlessly, or keep it growing, even producing, with lights and bloom sprays. There are many online threads about overwintering your peppers. Check out tips from several experts to make your efforts count!

Personally, there are so many tasty fresh winter foods that grow well here in our SoCal ‘winter,’ that I am more than happy to replant peppers in spring!

Pests & Diseases

For Blossom End Rot, see above under Care.

Early Blight and Verticillium Wilt are a problem at both Pilgrim Terrace and Rancheria Community Gardens in Santa Barbara. Please see more about them and what to do here.

See more about Pepper pests and diseases at the UC Davis IPM page.

Choose Resistant varieties.

Bell peppers are at their sweetest and are highest in Vitamins A,  C and carotenoids when fully mature! When choosing bell peppers for eating, select those that are firm, heavy for their size with shiny, bright and vibrant richly colored skin! The bell pepper’s sweetness increases as their color changes from green to their final color if they are a color changing variety.

Their stems should be green and fresh looking. To avoid breaking branches, use a sharp knife to cut, instead of pulling.

It’s nice to know that if not optimally ripe vitamin C and carotenoids in bell peppers will actually increase with refrigerator storage over the next 10 days!

Storage

For maximum flavor, eat peppers on the same day they are picked! Room temp is best for peppers, leave them on a kitchen counter for a day or two to ripen further. Rinse with cold water just before you use them. Bell peppers are very sensitive to ethylene gas so don’t store them with fruits and vegetables that produce ethylene gas. If you put them in the fridge, do it only 1-3 days and use immediately upon taking out of the fridge. Don’t remove their cores because they are quite susceptible to moisture loss. Peppers are warm-weather fruits that don’t store well in cold temps. If you have too many peppers, consider the following storage options.

Freezing This is the easiest storage method. Peppers freeze well without blanching. Thawed peppers still retain some crispness and can be used in cooked dishes or raw in uncooked preparations. Their flavor is retained, so use frozen peppers primarily for adding ‘spice’ to soups, stews, and sauces. If you stuff the peppers before freezing, you’ll have a ready-made dinner, perfect for the microwave.

To Tray Freeze Sweet Bell Peppers

Wash and core peppers. Chop, dice or slice according to how you plan to use them.
Spread in a single layer on a tray of a cookie sheet. Place tray in the freezer for an hour or longer. Loosen pepper pieces from the tray and pour into zip closure freezer bags. Immediately place sealed bags in the freezer. The pepper pieces will remain separated for ease of measuring. Simply remove as many as you need, reseal the bag and return to the freezer. Or bag them separately in the amounts you plan to use them.

Pickling/Canning Peppers are low-acid fruits so require canning under pressure. It’s easier to pickle peppers as you would cucumbers in a crock filled with a simple brine of four cups of water, four cups of vinegar, and 1/2 cup of pickling salt. Add a clove or two of garlic and some fresh herbs for delicious added flavor.

Sweet Banana, Sweet Hungarian, Cubanelle are long, narrow tapering down to one, two or three lobes. They are thin walled, Cubanelle the thinnest. They are usually picked when light yellow or green. Because they have less water content than bells, they are perfect for frying. ‘Sweet Banana’ was the 1941 All America Selections Winner!

Pepper! Colorful Decorative Ristras!Drying This method works best with thin-walled peppers, particularly the smaller varieties that can be dried whole right on the plant. The key to drying peppers is doing it slowly to retain their color and flavors. Perfect for spicing up bland backpacking meals!

Another form of drying is in brilliant wreaths and Ristras!

You can grind chiles into culinary or medicinal powders! They retain their lovely colors! Paprika is a dried powdered form of bell pepper, and though we are used to seeing red paprika, a paprika can be made from any color of bell pepper and it will end up being that same color. Both the decorative forms and these potent powders make sensational gifts!

Seed Saving

To prevent cross-pollination, hot pepper plants should not be planted near sweet or bell pepper plants. TRUE! Plant at least 400 feet between varieties to ensure absolute purity. That’s important info for seed savers!

Harvest mature, fully-ripe peppers for seed. Most bell peppers turn red when fully mature. If frost threatens before peppers mature, pull entire plant and hang in cool, dry location until peppers mature.

  • There are two methods to process pepper seeds, dry and wet. The dry method is adequate for small amounts. Cut the bottom off the fruit and carefully reach in to strip the seeds surrounding central cone. In many cases, seeds need no further cleaning.
  • To process the seed from large amounts of peppers, cut off the tops just under the stem, fill a blender with peppers and water and carefully blend until good seeds are separated and sink to bottom. Pepper debris and immature seeds will float to the top where they can be rinsed away. Spread clean seeds on paper towel and dry in cool location until seed is dry enough to break when folded.

FYI Birds are not sensitive to capsaicin, the heat factor in chilli peppers, and are therefore the main dispersers of the seeds!

Pepper Hot Oil & Healing Spices

Remedies: Hot Oil! Healing Spices. The countless health benefits claimed are exciting and enormous! Cayenne is said to stop heart attacks. Hot oil works wonders on knees.

Nutrition: I’m not sure people really eat peppers for nutrition, LOL! Peppers are in a food category all their own! Choices are made according to the Scoville Scale, how hot or not they are! At the lower end of the scale, nutrition may factor in somewhat, but it is more likely a visual choice, shape and color, whether for salad or type of cooking you will use the pepper for.

Sweet luscious Bell Peppers have a whopping 169% of the daily value of Vitamin C we need, but who thinks of peppers as a source of Vitamin C?! More we think of low calories, but most of all, that delicious taste! But look, here’s more! Absorption of dietary iron is significantly increased when consumed with fruits or vegetables that are high in vitamin C. Eating raw bell peppers with iron-rich foods like meat or spinach, may help increase your body’s iron stores, cutting the risk of anemia. Eat peppers!

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!

APRIL is for Heat Lovers! Pull back your mulches, let soil heat up, PLANT!

Why not start with an AAS (All America Selections) 2011 Winner?!
Pepper ‘Orange Blaze’ F1  Early ripening orange variety, very sweet flavor, multiple disease resistances!

AAS 2011 Winner - Orange Blaze F1 Pepper

Get out last year’s garden notes if you made any, and review for varieties you liked, where you got ‘em, how much to plant!

CORN!
Plant in blocks, not rows, for pollination.  When tassels bloom, break off pieces and whap them on the silks!  Each silk is one kernel, each needs one grain of pollen!
Corn hybridizes – plant only one variety, or varieties that don’t have pollen at the same time.  This is pretty much not doable at a community garden since everyone is planting all kinds at any time, so if you harvest seeds, don’t expect true results!

Heat tolerant, tipburn resistant lettuces – Nevada, Sierra, Black Seeded Simpson, Jericho Romaine
     Slo bolt cilantro, arugula in semi shade (among your corn?!)
Eggplant love humidity and heat.  Tuck ‘em in between, right up against, other plants.  Near the cooler coast plant the longer length varieties that mature earlier.
Jicama, limas, melons, okra, peppers, seed potatoes, pumpkins
From Seed:  basil (Nufar is wilt resistant), chard, green beans (while peas finishing), beets, carrots, corn, endive, New Zealand spinach, parsley, radish, squash – summer & WINTER, sunflowers, turnips.  Coastal gardeners, get your winter squash in NOW so it will have ample time to mature.
The radish variety French Breakfast holds up and grows better than most early types in summer heat if water is supplied regularly.

PreSoak and/or PreSprout for 100% success!  Click here for details!  Per eHow:  How to Soak Watermelon Seeds in Milk Before Growing.  Sometimes the seed coat carries a virus, and the proteins in milk will also help deactivate the virus.  Read more 

Transplants:  cucumbers (hand pollinate?), tomatoes, watermelon
WAIT FOR MAY to plant cantaloupe
Herbs from transplants – oregano, rosemary, sage, savory, thyme 

Plant successively!  If you put in transplants now, also put in seeds for an automatic 6 week succession!  Plant different varieties (except of corn if you want true seed – see above)! 

If you overplant, thin for greens, or transplant when they are about 2 to 3 inches high.  Lettuce, carrots, onions.  Too many stunt each other.  OR, this from Santa Barbara Westsiders Lili & Gabor:  Overplant mesclun on purpose, then mow the little guys!  If you are at home, plant densely in a planter bowl, cut off, leaving 1 ½” of stem still in your soil.  They will regrow, you will have several months’ supply of tasty baby greens.  Plant two or three bowls for more people or more frequent harvest!  Give a bowl as a gift! 

Tomatoes
Plant for excellence
 – Throw a handful of bone meal in your planting hole along with a handful of nonfat powdered milk, worm castings, compost/manures, mix it all up with your soil.  Sprinkle the roots of your transplant with mycorrhizal fungi!  That’ll do it!  Stand back for bounty!
REMOVE LOWER LEAVES OF TOMATOES  Wilt prevention.  Water sparingly or not at all after about a foot tall.  Wilt comes from the ground up the leaves and is airborne. Remove any leaves that touch the ground or could get water splashed.  Don’t remove suckers – airborne fungi can enter open wounds.
Sorry, NO HEIRLOOMS if you know the soil has the wilts.  Heirlooms don’t have resistance.  Get varieties with VF on the tag or that you know have resistance/tolerance.
Mid day, rap tomato cages or the main stem, to help pollination.  55 degrees or lower, higher than 75 at night, or 105 in daytime = bud drop.  Not your fault.  Grow early varieties first that tolerate cooler temps.
Pilgrim Terrace Community Garden Kevin and Mary Smith have had successes with 2 blight resistant/tolerant determinate varieties, New Hampshire Surecrop, a 78 day, great tasting slicer/canner, and Legend, a very early 68 day!  Ask for them, and more Jetsetters, with unbelievable VFFNTA resistance/tolerance, at your nursery.  See Tomatoes and Wilts here at the Green Bean Connection Blog for a list of additional resistant/tolerant varieties and tips!   

Maintenance!  Sidedress when blooms start.  Fish/kelp, foliar feed Epsom salt for Solanaceaes, seabird guano (not bat) for more blooms, manures for lettuces and leaf crops like chard, collards.

Tomatoes & the Wilts – Part 1

Wolf Peach!!!!  Did you know – our tomato originated in South America and was originally cultivated by the Aztecs and Incas, came to Europe in the 1500s.  People were warned not to eat them until the 18th century!  Wolf Peach comes from German werewolf myths that said deadly nightshade was used to summon werewolves!  ‘Tis true, tomatoes are of the deadly nightshade family, and does have poisonous leaves.  But you would have to eat a LOT of them to get sick!  But they are not good for dogs or cats!  Smaller bodies, right?

Tomatoes & the Wilts – Part 1

Tomato - Healthy SunGold!

Tomato – Verticillium Wilt

Above on the left is a very healthy Sun Gold cherry tomato and happy owner.  On the right is a verticillium wilt fatality, not old age.  Almost all of us have had tomato wilt fatalities.  Very sad to see, disappointing and frustrating as XXX!  Tomatoes are pretty dramatically affected, but many plants get the wilt, including your trees, shrubs and roses.  Veggies affected are cucumber, eggplant, pepper, potatoes, rhubarb, watermelon, artichoke, beet, broad bean, strawberries, raspberries.  Cool, damp weather, like we had here in Santa Barbara area ALL last summer, referred to as the ‘May grays’ and the  ‘June glooms,’ is the worst. 

The leaves fold along their length, the stems get brown/black spots/blotches on them, the leaves turn brown, dry and die.  It is a fungus in the soil that is also windborne.  There may be too much N (Nitrogen), too much manure – lots of gorgeous leaves but no flowers.  That’s an easy fix, add some Seabird (not Bat) guano to restore the balance, bring blooms, then fruit.  The wilt is tougher.  When the toms get about a foot tall, STOP WATERING!  Remove weed habitat and don’t mulch.  The fungus can’t thrive in drier soil. Water the toms’ neighboring plants, but not the toms.  Tomatoes have deep tap roots and they can get water from below the wilt zone.

It is better to pull infected plants, called the one-cut prune, because their production will be labored and little compared to a healthy plant that will catch up fast in warmer weather.  And you will be more cheerful looking at a healthy plant.  Heirlooms are particularly susceptible, so get varieties that have VFN or VF on the tag at the nursery, or are a known VFN variety.  The V is for Verticillium, the F Fusarium wilt, N nematodes.  Ask a knowledgeable person if the tom doesn’t have a designation, or check online.  It’s just a bummer when plants get the wilt.  If you are one who removes the lower leaves and plants your transplant deeper, don’t let the lowest leaves touch the ground. When your plants get bigger, cut off lower leaves that would touch the ground BEFORE they touch the ground or leaves that can be water splashed – some say take all up to 18″ high!  The wilt gets into your plant through its leaves, not the stem.  Don’t cut suckers (branches between the stem and main branch) off because the cuts can be entry points for windborne wilts.  Wash your hands after working with each plant with the wilt so you don’t spread the wilts yourself.

There’s little you can do for/to the soil to get rid of the wilt.  The only method I know that most of us can afford is Solarization.  Put black plastic tightly to the ground during a couple weeks of heat to kill it.  Problem is twofold.  1) That would be high summer to get that heat, so you can’t have your summer crop in that area.  If you have enough space, it’s doable.  If you only have a small space, that means no toms this year.  2) We are coastal and the temp needed to kill the wilt isn’t maintained over a two week period.  Sigh.  So we do our best, resistant varieties, little water, removal of lower leaves, remove infected plants.  A lot of smart local farmers dry farm tomatoes, and it’s water saving. 

You can use straw bale planting, or make raised box beds and fill them with soil that isn’t infected with the wilt.  That can help for awhile.  Here’s a link to my Green Bean Connection blog post on Plant a Lot in a Small Space that has a bit on hay/straw bale gardening!  It’s about 2/3s down the page, with link for instructions!  But.  Not only are the wilts soil borne, but airborne.  That you can’t do a lot about except ask everyone with infected plants to remove them.

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. Do not mix untreated soil into the solarized bed And please, do NOT compost diseased tomatoes, or any other diseased plant.  That’s how you spread soil born fungi, let alone that they are also spread by wind, are airborne.  If your neighbor has a diseased plant, don’t be shy to respectfully and gently ask them to remove it.  Remember, they raised that child.  How hard was it for you to give up your plant?  Especially the first time.  See?  They may not even know about wilts.  Educate them if possible.  Tell them how you learned about it.  Offer to send them the link to this page.

Initially it was defined as the pest suppressive action of decomposing Brassica tissues, but it was later expanded to include animal and plant residues.  Other Tomato Questions & Cures – Holes, spots, brown areas?  Here is an IPM (Integrated Pest Management) image page from UC Davis that is likely to answer your question!  It includes diseases and pests.  See more images at Colorado State U Extension.
