I love Val Webb’s image and she and I both love COMPOST!  She says:  There’s an irresistible alchemy involved when you can start with garbage and end up with a wildly nutrient-rich substance that has been likened to Ghirardelli chocolate for earthworms.

Composting is EASY! Start Now!  Get your soil fat!  The sooner you plant, and plant in tasty soil, the sooner you get a great harvest!

There’s compost and vermicompost, hot and cold compost, compost in place, trenching, to name a few.  You have options!

Compost is decayed organic matter – poops – that’s manures, dry leaves and straw/alfalfa, wet grasses and kitchen wastes. Compost has a variable amount of Nitrogen in it depending on what has been composted and how the compost was made. Some studies show unturned compost has more Nitrogen than turned compost. Homemade compost can be up to 4 N, as is fish emulsion and chicken manure. Steer is 2, horse 1.7. If you need a quick boost for a yellowing N starved plant, go for bat guano, or easily assimilable blood meal, both at 10 N! Be careful with that bat guano, it’s hot and can burn your plants. And both are pricey. Get just the amount you need at Island Seed and Feed’s bulk bins.

Vermicompost is worm poop. Politely, worm castings. Simple as that. Red wriggler worms are easy to raise, will eat lots of things but do best with tender stuff, your green kitchen waste. They love cantaloupe and melon rinds, nesting in avocado shells, egg shells keep their pH neutral. Wrigglers are surface feeders not earthworms. If you put wrigglers in the soil, they die. Worm castings (vermicompost) have negligible N, about .05, are NOT A FERTILIZER, but do a lot of other good things for your plants. Highly recommended.

Hot compost has to be made carefully, have just the right mix, be tended like a baby, and defies many attempts to get it hot! If you don’t get the combo of your materials right, you are cold composting. The advantage of hot composting is it is fast, kills bad creatures and weed seeds. Also kills the good guys. But. Only in the parts of the pile that actually get that hot. The whole pile never gets that hot, like the outside of the pile. Even if you turn it so the outside goes inside, it’s hard to guarantee it will all get that hot, so be advised. It’s pretty cute to see all those little plants that spring up in the pile….

Cold compost is just throwing your done plants or trim, preferably not diseased or pest infested, into a pile or your compost enclosure, layering with some wet or dry material as needed. It might get hot, it likely won’t. It will decompose if you keep it moist. If not you have dead dry stuff, no nutrients.  Some studies have shown that cold compost is more nutritious than hot compost.  Makes sense since you aren’t burning off Nitrogen and other goodies including beneficial insects and microorganisms.  If your stuff doesn’t turn black and fluffy and smell good when it is decomposed to unrecognizable pieces, you don’t have compost. Perhaps you could use it as mulch?

Composting in place, sheet composting, Lasagna Gardening, is a time saver, no moving later. Chop and drop on the spot, add dry/wet materials as needed, amendments, red wrigglers, let nature do the work.  Especially add some chicken manure before you add your layers, because decomposition uses Nitrogen!  If you are starting on top of turf, using cardboard as your bottom layer, be sure to SATURATE the cardboard.  Don’t rush this part.  Really saturate it.  You want it to last long enough for the grass underneath it to die, to keep the grass from growing up through your pile; you also want your cardboard to decompose so your plants’ roots can grow through it when your pile sinks as the pile decomposes.

Trenching kitchen trim is traditional – cover it and forget it! Crushed eggshells, torn tea bags, coffee grounds. Six inches deep is all you need to do. Cover with the soil, water as usual, your stuff will disappear in about a week! Don’t put in meats or oils that attract digging predators, or grains or cereals that will attract mice. Leave out citruses and spicy foods.

Start Now! 10 Easy Steps to Make RICH COMPOST!

Make the most out of your finished plants or trim; use them for compost, organic fertilizer! A compost enclosure is a fine garden investment! Keep it humming! Dig your compost in around your plants, plant IN your new compost! Surface compost Nitrogen just off gases, so put a layer of soil over your compost to keep the Nitrogen right where you need it, in the soil feeding your plants.

1. Get or make your enclosure, a good working size for you, then layer, layer, layer! Half inch layers are ideal, but do what you can.  A pile 3′ by 3′ is your best minimum if you want a hot pile.  Enclosures can be free pallets on Craigs List tied together, plastic beehive types to keep the rats and mice out, the circular hard black rubber kind, to expensive rolling types, garbage cans with bottoms removed, holes made in their sides!  Do what works for you!
2. Dry stuff first so it will get wet from the stuff you put on top.  That’s ‘brown’ – dry ingredients such as dead leaves, wetted newspaper or cardboard, alfalfa/straw.  The formula is 2 dry, brown to 1 wet, ‘green.’
3. Layer up with your kitchen waste you saved, undiseased green waste from your garden or greens recycle bin. Avoid hard woody stems and seeding weed plants. Cut up large items, halve whole items like apples, potatoes. Tear teabags, crush eggshells.
4. Lay in a few yarrow leaves to speed decomposition. Grow yarrow by your composter for handy use.
5. Inoculate with a sprinkle of soil, living micro organisms, that multiply, munch and speed composting.
6. Sprinkle your layers with aged manure (keep a bucketful next to your composter) to enrich it.
7. Keep layering up to 3’ high or until you run out of materials.
8. Keep your composting materials moist, to keep them live and decomposing.  Don’t let them dry out – dry is dead, nothing happens, nutrients are lost, time and space wasted.
9. Cover with a large piece of *folded heavy mil black plastic to keep your compost moist, and dark so any worms that take up residence work up through the whole pile, to the top .
10. Keep adding to it, stir or turn often to oxygenate, weekly if you can.  Composting organisms need lots of air to operate.  Keep it moist but not drippy and drowning.  Some studies show compost is more Nitrogen rich if you DON’T turn it!  Hmm…read on.

If you are not able to do that much heavy turning or don’t want to take the time, simply, push a long stick into your compost, several times, in different places, to let oxygen in.  Or, if you are inclined, at intervals in your pile, as you build it, you can insert, horizontally or vertically, 2″ PVC pipes, that have had holes drilled in them every 6″ for aeration.  If you are going to insert horizontally, make your holes on one side only; put the holes side down to keep them from clogging.  Make sure both ends stick out so there is air flow through the pipes.  If you insert vertically, drill holes all around the pipe.  If you use a larger diameter, line it with wire mesh to keep it from filling with debris.  Once made, you can use your PVC over and over.  Other alternatives are to make wire mesh cylinders or tie a bundle of twigs together.

Your compost is finished when you no longer recognize the individual materials that went into it. If you are have a small compost batch, when ready, lay out your *folded plastic cover, pitchfork the still decomposing stuff on top of your pile onto your plastic.  Use that good stuff at the bottom where you want it. Or plant in the nutrient rich spot where your composter was!  Put your composter in a new spot, fork the stuff still decomposing back in, add new materials, recover, do it again!  The process slows down in winter, speeds up in summer, generally you have some compost in 6 to 8 weeks.

If you have time, throw a cup or so of compost in a bucket, fill with water, let sit overnight, voila, compost tea! Soak your seeds in it before planting!  Pour it round your plants or use your watering can to spray it on their leaves, both tops and bottoms – foliar feeding.  Your veggies will thrive!  If you have a lawn, make aeration holes with your spade fork and pour the tea down them.  You soil will start to live again!

Your soil and your plants thank you!

Water is the driver of Nature.  –   Leonardo da Vinci

When, Who, How, & How Much to Water

Midday, on a hot day, watering will burn the leaves.
Evening watering promotes mildew, fungus growth.  Plants drink during the day, so AM watering is best.

Plants that need little or no water and why:
Onions, garlic, that are flowering, going to bulb, needing to dry
End of season tomatoes that you want to have a stronger flavor
Tomatoes in soil with Fusarium and Verticillium Wilt fungi in the soil.  Fungi don’t do well in dry soil.

Plants that need water almost daily, sometimes twice daily 
Shallow rooted beans, beets, bunch onions, cucumbers, peas, strawberries
Celery and chard, lettuce, arugula – leaf crops, to keep them growing fast, tender and tasting sweet.
Planted seeds, seedlings, newly planted transplants, must be kept moist; if they dry, they die.  Put up temporary shade.

Use a watering can for seeds and tender seedlings so seeds aren’t washed away or seedlings broken.

Most plants need only an inch of water once a week unless it is hot and/or windy weather.  Most gardeners over water by two times as much as is needed!  Overwatering drowns plants, and kills micro soil organisms; they don’t get oxygen.  Soil structure is destroyed as air spaces cave in.  Overwatering also causes poor root growth making it difficult to move enough water to the leaves during hot weather.

Irregular watering results in misshapen fruits, tomato flower drop, can stop production

Fuzzy plants like tomatoes, eggplant, don’t do well with watering on their leaves.  Water underneath please.

Plants that are mulched generally need less water.  Poke your finger in the soil to see how deeply it is moist.  More on mulching next week.

Water and Pests & Diseases 

Overhead watering contributes to mildew on beans, squash, peas.  It spreads Strawberry Leaf Spot and other waterborne diseases 

Tomatoes:  stop watering when about a foot tall.  Water around them, but not right at them.  Keep back about a 2’ perimeter to reduce Fusarium and Verticillium Wilt fungi.  If you do water them, on mature plants, cut off the lower leaves, up to 18” high, to prevent soil splash when watering.  The fungi are especially taken up by leaves touching the ground.

Flush off aphids and the undersides of broccoli leaves and broc side shoots, kale leaves, especially the curly varieties.

Flush white flies from the undersides of broccoli leaves, kale, beans

BE JUICY!

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, Yellow Flag effect

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

15 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. Plant cukes and toms on a special raised mound/basin with the bottom of the basin above the regular soil level. See more on this page in the section, Special Planting and Growing Tips!
  4. 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, NOT in green waste or your compost.  
  5. **Create a soil barrier, mulch! Newspaper/cardboard covered with mulch or grass clippings doesn’t let the soil dry out. Moist soil is fungi habitat – we want that soil to dry. Use no more than one inch of straw. It is easy to lay on and allows light to get through and air to flow and dry the soil, stops the splash factor. Above all, you don’t want wet soil to contact your plant’s leaves. When that straw gets tired and flattens, trash it and replace with new clean light fluffy straw.   
  6. **Avoid wetting foliage when watering, especially in late afternoon and evening. Water at ground level! Watering the leaves creates a humid micro climate; the fungus produces spores. Dry leaves. Dry leaves. Dry leaves. No moisture, no spores.  
  7. **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. And getting more sun, your toms will ripen sooner! 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. In the case of tomatoes, scattered interplanting, biodiversity, is always a better choice than row planting where disease easily spreads from plant to plant.  
  8. **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.  
  9. **When they are about a foot tall, water neighboring plants, but not your toms. Plant water loving companion plants, like Basil or the Plant Dr Chamomile, next to your toms; water them all you want! Make a basin around your toms to keep water OUT! That keeps the soil drier near your plant, so the fungi can’t thrive there. Your tomatoes will get plenty of water by their deep roots.  
  10. **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 thinning 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. Wash your hands, in a rinse of water & alcohol, frequently so you don’t further infect healthy parts of your plant.  
  11. **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.  
  12. 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.  
  13. **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.  
  14. ****At the end of the season remove & trash, don’t compost or put in green waste, 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.  
  15. **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 crushed 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 half teaspoon 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 1/4 cup 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. Some gardeners won’t use solarizing because it kills beneficial soil organisms too… 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, infected trimmings or removed leaves, or any other diseased plant. That’s how you spread soil borne fungi, let alone that they are also spread by wind, are airborne. Put them in the trash, not green waste. 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.

Biofumigation  Biofumigation is a sustainable strategy to manage soil-borne pathogens, nematodes, insects, and weeds. 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. Do take a good look at it!

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