Amendment Biochar Applying

Charcoal-like biochar improves soil hydration and enhances agricultural production while it curtails nutrient leaching, increases nitrogen available to plants and reduces the release of gas pollutants. A new study by researchers at Rice University and North Dakota State University gathers current and potential sources of government support to promote the production and use of biochar. Credit: Ghasideh Pourhashem, from the January 11, 2019, Rice University post. Read more Biochar holds promise for sequestering carbon and cleansing polluted air.

Fans rave about its virtues. Some are skeptical but want to learn more. So, wanting to learn, possibly use, I typed in ‘2018 2019 Biochar pros cons’…carefully read the latest noncommercial posts and their comments threads.

A few years ago a knowledgeable gardener I know raved about biochar. Now, some years later, recently a friend sent an article that turned the tables enough to make me want to check it out. One is how it was compared with natural soil that is replenished with biochar by forest fires. Two is how Biochar has several soil sustainable features, but foremost is how it keeps Carbon in our soil hundreds, maybe even 1000s of years! And that is to say nothing of its water holding capacity! Carbon is the foundation of our soil ecosystem. Three: Also, I recalled how amazingly my winter and summer garden plants grew last year. It started with a collusion of happenstance. I planted quite late, Dec 10, 2018 during the Thomas Fire ash fall. The ground was literally solid white with ash and chunks. But this winter my plants didn’t do nearly as well. Hmm… Granted, the ash is not biochar, but it’s a relative – it came from the high heat of a forest fire.

Right now, planet wide, by many, Biochar is considered crucial to our planet’s sustainability. Using it is a regenerative practice that will help our plants not only weather extreme conditions, but thrive!  

BIOCHAR RESEARCH

There are technical discussions, both pro and con, in a language all their own, to simple explanations for the home gardener. The main research is in consideration of farmers with vast tracts of land that could have significant impact on climate change.

CONSIDERATIONS

Nov 29, 2018 From a field day presentation at California State University-Fresno, here are some points from Suduan Gao, a research soil scientist with the USDA San Joaquin Valley Agricultural Sciences Center in Parlier. She talked of the potential of applying a biochar amendment to help in water and nutrient management.

Biochar is charcoal used as a soil amendment. It is made from biomass through thermal decomposition [fire]. Gao said it increases water use efficiency and nitrogen retention, reduces leaching, cuts nitrous oxide emissions and reduces ammonia emissions.

Gao said nitrogen dynamics are influenced by biochar and are highly affected by irrigation levels.

She said ammonia volatilization loss was substantially higher when fertilizer was applied only a few times in a larger amount than when it was applied more frequently in smaller amounts.

“Soil accumulates more nitrogen at lower irrigation levels than at higher irrigation levels,” Gao said. “The accumulated nitrogen, however, can be all leached during the rain system.” [Fertilizing after rains is more better!]

She said there were no significant biochar effects on ammonia, nitrous oxide and soil nitrate concentration, but there was a significant interaction between biochar and irrigation.

PROBLEMS WITH BIOCHAR? Fabulous or Fantasy? Is it too good to be true? There are extensive rebuttals to its use, even warnings that it’s not all the fans say, can even cause harm!

Nov 18, 2010 DR MAE-WAN HO said ‘Turning bioenergy crops into buried charcoal to sequester carbon does not work, and could plunge the earth into an oxygen crisis towards mass extinction.’ She further says: …implementing the biochar initiative could be dangerous, basically because saving the climate turns out to be not just about curbing the rise of CO2 in the atmosphere that can be achieved by burying carbon in the soil, it is also about keeping oxygen (O2) levels up. Keeping O2 levels up is what only green plants on land and phytoplankton at sea can do, by splitting water to regenerate O2 while fixing CO2 to feed the rest of the biosphere.’

  1. She cites: A ten-year trial in Swedish forests showed that buried charcoal appear to promote the breakdown of humus, the decomposing plant matter on the forest floor, thus completely offsetting the carbon sequestered in the charcoal.
  2. She discusses examples of the stability of biochar stating that it isn’t always stable. [In a 2012 Mother Earth News post, Editor Dr. Kehres (Journal “Humus and Agriculture“) summed up a symposium: “Biochar appears over-rated — the biochar claim to 1,000 year stability is revised downwards to 10 to 100 years, roughly the same as compost.”]
  3. She warns that things that happen so fast now that we have the internet and huge commercial organizations, a lot goes on without public awareness or understanding and no testing. Since this one expressly claimed climate change remediation, it was touted to be necessary immediately. Some fads are found to be faulty later.
  4. She gets into comparisons of interest to gardeners, stating that Biochar effects on soil fertility are not always positive. Field trials were conducted on cleared secondary forest with 15 different amendment combinations of chicken manure (CM), compost (CO), forest litter, chemical fertilizer (F), and charcoal (CC) applied once on rice and sorghum, and followed over four cropping cycles. Chicken manure gave by far the highest yield over the four cycles (12.4 tonne/ha). Compost application came second at about half the yield, but was still four times higher than chemical fertilizer. The control, leaf litter (burnt and fresh), and charcoal treatments gave no grain yields after the second season, and were discontinued. Further, in combination with compost, charcoal amendment decreased yield by about 40 percent compared to compost alone, and only improved yield in combination with chemical fertilizer.

Read the comments on this page for rebuttals and further information. It is suggested Biochar is not THE answer, but part of a complex mix of possibilities.

This 2013 Mother Earth News post Biochar: Not All It’s Ground Up to Be? states the appropriate use of Biochar depends first on soil type. Some soils retain nutrients very well without any amendments like biochar. Tim Crews says: ‘If you’re cropping on soil types other than Ultisols or Oxisols and you manage your organic matter (residues, manure, compost, etc.) well, you don’t need biochar. It won’t do anything for your fertility.’

Second, a ‘situation in which biochar could provide benefits is on very sandy soils in arid climates, because of its ability to improve such soils’ water-holding capacity, reducing drought stress on plants. But making biochar requires large quantities of bulk plant material, and the biochar factory needs to be close to the source of that material; therefore, the product would have to be manufactured in or around highly productive lands or on vast areas of unproductive lands, and then be hauled long distances to the arid environments where it’s to be applied.’ Not only is the available quantity of crop residue per acre too small, but to haul residues off of cropland to a biochar plant would be to further rob the soil of organic matter, while paying a price in energy and other resources as well. After all that, some ‘studies that found yield increases with such heavy application found that after a few years, soil carbon was no higher in biochar-treated plots than in control plots.’

Biochar has been under discussion for years! When you are doing your own questing about it online, look for current posts and research. Note whether the post is on a commercial site, a university, posted by a farmer, if the poster is knowledgeable, what their credentials are or aren’t, if they have experience. Remember that universities make money from research grants on popular topics and sometimes the donation is made by a company. Go to permaculture sites for a look at possible long term possibilities, concerns. Look for pros and cons.

In 2018, the agriculture application segment accounted for 71.1% of the total biochar demand. That makes sense because they have the biggest land holdings. [But it also means 28.9% is used by others, including home gardeners! That’s a big % considering the sizes of their small gardens!] Quoted from a Biochar fan, he says ‘However, a large number of farmers still lack in knowledge about the product and its benefits.’ My question back to him was ‘Do you know what % of farmers use biochar?’

Amendment BioChar and Compost + Manure Yields Great Results!

Some say Biochar alone added to poor soil has little benefit to plants, but when used in combination with compost and organic fertilizers, it can dramatically improve plant growth while helping retain nutrients in the soil.

When would you, a home veggie gardener, use biochar?

First, are wood ash and biochar the same thing? Yes and no. Biochar is made at 450 °C/842 degrees F with low oxygen and wood ash is made at 870 °C from the same mixed hardwood. What about BBQ charcoal? Not the same thing as wood ash or biochar! Not recommended for garden use.

How do you even know if you need Biochar? Was there a forest fire ever there and you already have it? They say biochar comes from such fires and lasts 100 to 1000 years, or 10 to 100 depending on where you read… That translates to the question whether Biochar is considered to be stable or not and under what circumstances.

Have you been applying wood ash from your fireplace regularly? Some gardeners say Yes, used it for years, readily absorbed, amazing crops! Great substitute for lime to raise pH. Others say it’s grey death. It has a high pH that throws off the balance of your compost/soil, can kill off the microbes that are producing your compost. Poster Mr Bill says: ‘Charcoal chemically functions like a sponge, absorbing many organic compounds. When placed in nutrient rich soil, it absorbs the excess nutrients and traps them in the soil. As the carbon in the charcoal is annexed by fungal colonies, those nutrients are released over time. By tying these nutrients up in the soil with charcoal, they resist erosion and release at regular intervals, rather than the feast or famine spikes in levels that occur with manual fertilization by humans.

However, ‘…added to poor soil, or soil deficient in even one nutrient (which may not be obvious), the charcoal’s sponge-like absorption can compete with the roots of plants for the nutrients, leading to increased disease susceptibility or irregular growth hazardous to the plant.’ So it’s good with good soil, bad with deficient soil.

Lord knows even a 10X20′ community garden plot has varying soil content within the plot for many reasons. In my case, I trench in kitchen waste given to me by neighbors. One eats lots of bananas, hence peels. One is a super juicer, greens, carrots, etc. + lettuce and avocado. Another is a senior tea drinker, so little bags along with old snacking grapes, a few eggshells, a bit of coffee and citrus peels, etc. I get them when they have enough. They put them in a bucket outside my door. I take them to the garden and trench them in where compost is needed most. Sometimes a certain kind of plant never thrives in one area no matter what I do. It would take a lot of soil testing to sort out these small areas. I do my own remediation by adding store bought fluffy compost, and chicken manure in general. Most of the time it works fine.

FYI! If you are using or opt to use wood ash as an amendment, DO NOT mix the wood ash with nitrogen fertilizer; a reaction can occur releasing ammonia gas.

Be careful with your choice to use biochar. Is your garden flourishing because it is high on temporary soil amendments that will be spent this season? Is one area doing great, another adjacent area not doing so well; great for one plant but not another? Does your summer or winter garden do well and the other season doesn’t? Plus, all Biochar is not created equal. Its pH and ash content vary depending on the temp it was created at and the feedstock (what was burned) used, whether that was contaminated or not. In general Biochar raises soil pH. You need to use the right amounts. In a community garden 10X20′ plot, where the soil pH varies within the plot, you don’t have room to test/experiment. The increase in soil pH with alkaline biochar will be higher in acid soils than in originally alkaline soils. However! If a biochar has less ash content it will decrease soil pH because of the organic matter content.

Clearly, fireplace ash that is added every season or spring, doesn’t function the same as biochar that lasts 100 to 1000 years. It is either used up or leached away by watering, otherwise, your garden would have the highest pH in history! If biochar can’t be removed from your soil, and lasts for 100 to 1000 years, and your soil is unfavorably balanced, you may need to adjust your soil for a long time. Ironically, it works best where you already have a super flourishing garden!

Note, the type of fire makes another difference. There is increased growth after a forest fire, but slash and burn techniques have a long term bad effect in just a few years. Definitely not sustainable. Wildfires get much hotter, average over 1600°F, than farmer-made controlled burn fires kept under 1000°F to clear a field. Wood burns differently at different temps; the coals have a different structure. Forest fires burn hot at the center with low oxygen and you get Biochar. Big difference. All fires are not equal.

Mr Bill made a convenient list for us home gardeners!

• Use on rich soil with no deficiencies
• Use to correct acidic soils, or amend the pH of the char before application
• Never use on acid loving plants like blueberries [strawberries, celery, beans]
• Add to compost after composting has finished, not during composting. The recommendation for application is about ½ cup per cubic foot of finished compost. [That’s not a lot!]
• Use in moderation
• Never use char from pressure-treated or painted wood.
• Don’t use petroleum based fire starters or fluids if you intend to use the ash.
• Fires started with alcohol or non-paraffin wax are acceptable for garden use.
• Be mindful of your nutrient levels and pH when using char, test regularly for best results.
• Not all char is equal, refuse from wood gasifiers or efficient wood stoves is preferable to that from your campfire, fireplace or grill, but all are acceptable for use given the correct use of your discretion.

Making Your Own Biochar Amendment in Place!

HOW to MAKE OUR OWN BIOCHAR?! 

Though it’s been many years since the Biochar cure has been offered and raved about, using biochar on a mass basis has not been implemented to an extent that is making a planet wide difference. But that doesn’t mean we can’t use it individually. The simplest way to do it is right where you will use it, just like the Amazon Indians did 2000 years ago.

First check your legal situation before you go for it! Per the Santa Barbara County Air Pollution Control District where I live: A burn permit is required for all outdoor burning activity except recreational (campfires) and cooking (BBQ). This includes: Agricultural Burning (see definition) … Residential backyard burning (permitted only in the unincorporated areas of the Santa Ynez Valley)

Highly flammable gases are released during pyrolysis, so make it outside, well away from buildings, animals and people!

Barbara Pleasant, famed author of 5 garden books, throws in her two cents! ‘Last year, I committed one of the great sins of gardening: I let weeds go to seed. Cleaning up in fall, I faced down a ton of seed-bearing foxtail, burdock and crabgrass. Sure, I could compost it hot to steam the weed seeds to death, but instead I decided to try something different. I dug a ditch, added the weeds and lots of woody prunings, and burned it, thus making biochar. It was my new way to improve soil—except the technique is at least 3,000 years old.’

Barbara words the process more simply… What’s biochar? Basically, it’s organic matter that is burned slowly, with a restricted flow of oxygen, and then the fire is stopped when the material reaches the charcoal stage. Unlike tiny tidbits of ash, coarse lumps of charcoal are full of crevices and holes, which help them serve as life rafts to soil microorganisms. The carbon compounds in charcoal form loose chemical bonds with soluble plant nutrients so they are not as readily washed away by rain and irrigation. Biochar alone added to poor soil has little benefit to plants, but when used in combination with compost and organic fertilizers, it can dramatically improve plant growth while helping retain nutrients in the soil.

She speaks of the Amazonian ‘dark earths,’ terra preta, that ‘hold plant nutrients, including nitrogen, phosphorous, calcium and magnesium, much more efficiently than unimproved soil. Even after 500 years of tropical temperatures and rainfall that averages 80 inches a year, the dark earths remain remarkably fertile…’ They were produced this very way, burning. …composts and other soil-enriching forms of organic matter last longer. …increased productivity by making nutrients already present in the soil better available to plants. …organically enriched soil retains nutrients for decades rather than for a couple of seasons. This charcoal releases its carbon 10 to 100 times slower than rotting organic matter. See the details  See Twin Oaks Forge for making charcoal in a barrel!

Why buy commercial Biochar? 

Jeremy Menefee says, first, because they use more advanced tools and techniques than the home producer can easily acquire, commercially-produced biochar is usually more consistent in composition and charred under ideal temperatures.

Second, they are able to produce inoculant tailored to specific uses. Vermont Biochar, for example, produces (by hand) several versions ideally suited for either leafy annuals, root crops, or shrub or woody perennials. Each uses a different composition of inoculant to tailor it for the specific application.

Experienced permaculturist Jeremy also says to Biocharge your Biochar! Even commercial biochar producers say their products benefit from being biocharged again once it’s on your property, to tailor it to your site conditions. Here are two easy methods he recommends.

1) Compost charging Even if you buy inoculated biochar, rather than producing it on-site, it will be improved by maturing in your compost. You can use as much biochar as you want, up to about an even 1:1 ratio with the compost, so don’t worry too much about overdoing it. The Biochar doesn’t break down in the process. You may have shorter compost times! Some experts recommend adding both manure and bones.

Quick tip: If you have time, a great way to get the most out of your biochar is to spread it an inch thick or less into your farm animal bedding. Then, when the bedding is spent, add it to the compost pile. [LOL Black Sheep?!] The biochar is essentially ‘double-charged’ in this way. Also, in addition to stacking functions of your animal bedding, this can help reduce odors. Anecdotal evidence suggests it can also reduce illness among your animals!

2) Rapid Charging! The other way to inoculate your biochar is a bit more labor-intensive, but you can complete the process in hours or days, not months. First, fill a 55 gallon (210 litre) drum with fresh water and biochar. If you are using municipal treated water, let it sit for a couple days to remove any chlorine. Then add compost tea or worm castings and leachate to the barrel with some soil from the area where you will use the finished biochar. For example, if you are going to apply the biochar to your fruit orchard, add some soil from around a robust and healthy tree in that orchard. This will help charge the biochar with the ideal microbiology for your specific orchard.

Once everything is well mixed, insert a long tube such as a length of PVC pipe into the barrel and direct air from a blower into the tube, or use a pond aerator and air stones. Aeration supercharges the inoculant and gives the beneficial microbes a massive head start, and helps them adhere to the biochar. Continue this for 12-24 hours.

Safety when applying Biochar amendmentBe careful when applying dry Biochar!

Wear a dust mask such as the 3M™ 8511 Particulate Respirator – N95 to protect your lungs. Moistening biochar can help a lot with dust control. Some Biochar is shipped with about 30% moisture content to help with dust control. Protective eyewear will reduce the chance of getting dust in your eyes. Wear gloves! Wear rubber boots that can be cleaned easily! Apply evenly on a dry, windless day. Mix thoroughly into the soil before planting.

How much do you apply? Doing it right depends on what kind of soil you have and it’s tested content, its pH, how much you want to raise the pH if at all. And, of course, none, if you don’t need it or your situation isn’t right for it!

There are different answers!

  • A company says: From everything we have seen in our own use and through the research of others a good “rule of thumb” is 10% of the planting area should be biochar. If your soil is absolutely horrible you should probably start with a 50/50 mix of biochar and compost and apply about 1/4 lb per square foot.
  • Typically home gardeners use 5-10% biochar in the top 6 inches of their soil.
  • A gardener says: If bought, follow the instructions on the bags, but I would suggest 50/50 with soil and the same for containers, and see your results the first season before you adjust quantities.
  • Farmer Jeremy Menefee says: It takes about 10 pounds of biochar to properly cover 100 square feet. For potted plants, use pure biochar at a ratio of about 1:16 with your potting soil – about ½ cup per gallon of soil. This ratio is good for raised beds as well, one gallon of biochar per 16 gallons of soil. If you inoculated your biochar in compost (at ratios up to 1:1), just apply compost as normal – the presence of biochar doesn’t change the amount of compost used.

How to apply? Simple!

  1. Made your own in place? Just add amendments of your choice, especially compost, and till it in.
  2. Purchased, preferably inoculated? Lay on about 1/4″, amendments and till it in. If you don’t have much, spread it out and add more each time you amend.
  3. If you’re not able to till, spread out your inoculated Biochar, cover with mulch to hold it in place, let Nature do the work for you.

Biochar IS big business. There is university research devoted to it for sustainable reasons. They make huge grant monies from it. Yale and Cornell, Ames Iowa, Delaware, Missouri, North Dakota, Rice U in Houston Tx to name just a few schools. Government is in on it too, for example the USDA’s Southern Regional Research Center in New Orleans. There are subsequent conferences, magazines, books, products at your nursery.

USBI Biochar 2019 – is the largest event in North America dedicated to advancing the sustainable production and use of biochar through scientific and engineering research, policy development, field practice, and technology transfer. It will focus on bridging scientific, industrial, practitioner, and policy gaps in biomass utilization for biochar and bioenergy production. June 30 – July 3 at Colorado State University in Fort Collins Colorado.

BIOMASS Magazine – Beyond the Hype

Check out the BioChar Journal …we want our readers to be confident that what is written in the Biochar Journal is based on sound science and practicality.

Local gardeners might see various products at their nursery. A blend in snowy Maine might be quite different than in SW SoCal droughty areas. Before you order up online, take this into consideration. When buying locally, look on the package to see where it was made, then check out those ingredients. The bag shown here is definitely intended as a pH raiser; it has biochar and lime!

For those of us gardening at community gardens, we need to think of what the next gardener’s soil needs might be after you leave. What if they primarily want to plant acid loving plants, those blueberries, strawberries, celery or beans? In keeping with rotating crops, planting in a different place each year, to avoid soil diseases various plants are susceptible to, we may need to stay flexible – amend each season or year with regular or acidic compost per patch as we go.

If you have a good size parcel of land for veg gardening, that you plan to keep for many years, soil test different areas. You might coordinate your Biochar choices with the land’s own natural flow, plant accordingly. Some sites say it takes about a year for the Biochar/soil relationship to be fully established. If you are planting in raised beds/containers, where soil is leached of nutrients due to higher soil temps, drying, in those structures and frequent watering to compensate, replacing spent soil/compost each year, Biochar isn’t going to work for you.

Making your own Biochar is cheap, but a lengthy process you hope you do right. Probably wise to have someone experienced with you when you do your first processes. First there is gathering the right materials, selecting the right place and technique for the kind of results you want, doing the burning. Then there is the biocharging process for it to do its best work. Buying Biochar can be pricey if you get the best, inoculated. If you put it where it can be used to best advantage, that is worth the one-time expense.

Your final decision to use or not use Biochar may be based on your instinct. You may decide not to use it at your current location or in a specific area of your garden. You might move, or be visiting in another gardener’s location and feel it is the right choice for that place. Maybe you will decide to wait and see. Honor your feelings. You might not save the planet today, or maybe you will by using succinct educated choices.

Bless you for being a garden guardian, a caring Earth Steward.

SideDressing your veggie garden with Ewe Poo and Pea Straw in Australia!

It’s mid-season now, so this weekend I’m giving the garden a boost by side dressing everything with some ewe poo and topping it off with fresh pea straw… [I think this is in Australia. It took a moment before I got it that it is sheep poo!]
x

Right NOW, June, starts feeding time! First let’s go over some general considerations and methods of sidedressing, then we’ll go through the summer favorites Feeding Schedule, in detail, plant by plant

Local Conditions Super soil, short summer, no feeding necessary. But if you have a long growing season of heat tolerant varieties like here in SoCal, plants making big leaves and lots of fruits, or plants that are harvested for their leaves, like summer lettuces, they need food! And that all depends on your micro niche where you are growing at home – some spots are hotter than others, maybe get more sun. Your plant produces more or less, needing more or less feeding. If your soil is not the best, feeding more frequently makes sense. And, so, give the best kinds of feeding you can – quality compost you made yourself if possible. If you plant densely, your plants are competing for nutrients, they will likely need more fuel, more frequently!

Varieties make a difference too! Long season indeterminate tomatoes, will likely do better with late season feeding. Early varieties, determinate tomatoes or bush beans, may not need feeding at all. Heavily and continuously producing pole beans make their own Nitrogen, but that may not be quite enough near their end of season or in very poor soil. If they start to slow down, the leaves yellow a bit, try a feed and see if they perk up. Near the end of the season feeding may not help.

Seasonal Timing Classic times to feed are at transplanting, blooming and just after fruit sets. Baby plants need more Nitrogen. They need to grow big, have a strong body to support all that fruit and make leaves! When it comes to blooming and fruiting your plant is beginning to work hard. We don’t need a lot of leaves now. Lay back on N and give your plants a good feed of more PK, Phosphorus for blooms and Potassium for disease resistance. NPK needs to be highest in P now.

Later in the season, if/when your plants are looking tired, slowing down, a feed can perk them up, extending their production time. Be sure other factors are well tended. Keep plants weeded so weeds don’t siphon off your plants’ food, especially when your plants are babies. Separate or thin young plants so they aren’t struggling for the same food. Early on use dark mulch to warm your soil, keep the soil moist, prevent light germinating weed seeds from starting. Weed out what does come up. Later in the season lay down reflective mulch like straw so your plants’ roots stay cool.

Your plants need adequate soil moisture so their roots can take up nutrients. Water after you feed and keep your soil as moist as that plant needs.

Feeding Methods aka Sidedressing

Foliar Feeding - rose upturnedThere are a couple ways to feed. Feeding your soil feeds your plants. Here are some equivalents: One handful of good compost per plant. That is equal to about one tablespoon of 5-10-10 fertilizer. Liquid fertilizer, ie fish emulsion, in your watering can is an easy way to side dress. Compost tea is redundant, since you already put compost in your soil, but a cupful of a mixed tea adds all sorts of things your compost doesn’t have.

Foliar feeding garden tea blends is a super enrichment that offers more options of trace factors. Even if proper nutrients are present in the soil, some nutrients cannot be absorbed by plants if the soil pH is too high or too low. Compost corrects soil pH issues and is one of the best ways to maintain the 6.5 ideal. Foliar feeding saves your plants while compost is doing its job. Foliar feeding is an immediate way to revive and stimulate stressed, tired, or diseased plants. If you have an ailing plant, repeated treatments can get your plant up to par soonest! See Teas! Compost, Manure, Worm Castings Brews!

Foliar Feeding Facts per Planet Natural:

• Tests have shown that foliar feeding can be 8 to 10 times more effective than soil feeding.
• Up to 90% of a foliar-fed solution can be found in the roots of a plant within 1-hour of application.
• Foliar supplements are an effective way to compensate for soil deficiencies and poor soil’s inability to transfer nutrients to the plant.

If you are container gardening, or have seedlings, use a spray bottle. If you are growing in the ground, get a watering can with a nozzle that rotates to spray UP under your plants’ leaves where some pests live. What goes up between the leaves will fall down and do the tops of the leaves at the same time! In other words, foliar feed your whole plant!

Applying granular fertilizers:  Scatter 8 inches away from the base of the plant on the side of the row or around the plant to just beyond the plant’s drip line to encourage root growth. Apply evenly. Raking the fertilizer into the ground is better than just applying on top of the soil, but rake very gently and not deeply to avoid breaking tiny surface feeder roots.x

Vegetable Gardening Gone Vertical - Trellis of beans and cucumbers!

Beans

Beans make their own Nitrogen, though sometimes not enough when they are in heavy production and it is toward the end of summer. They don’t make their own Phosphorous or Potassium.

Yellowing, mildew, white flies, ants and aphids? Pests may set in when a plant is stressed or weakened, but pests also like plants in peak condition! Do Aspirin and powdered milk sprays to up their immune system. Add baking soda to alkalize their leaves for mildew prevention. Best to do these treatments every couple of weeks, after significant rains and before trouble arrives! See more!

Tea mixes are good for improving their general health. Just imagine, with all those leaves, what foliar feeding can do! Same for those cucumbers below the beans in the image!

Fabulous Array of Cucumber VarietiesCucumbers

Some gardeners prepare their cukes, melons, squash, peppers and tomato soil well in advance, in fall for spring! Compost in place – pile on manure, chopped leaves and grass, sprinkle on coffee grounds and kitchen scraps, wood ashes from winter fires, etc. In spring dig a foot square hole, fill with your luscious compost, plant your seed right in that compost! Lasts all season if you live in a short season area, and no compost is wasted where no plant is planted! As long as you get that compost out to just beyond the feeder root area your mature plant will have, it’s good.

Some say most granular fertilizers leach from the soil rather quickly due to watering. That is why the instructions say you should reapply periodically throughout the season. Time release pellets do better. But adding organic material to your soil not only adds nutrients, it loosens the soil, attracts worms and other soil building critters and helps your soil retain moisture and nutrients.

Feed your cukes when they first begin to run (form vines and sprawl); again when blossoms set. A big vined short rooted, long fruited variety of cucumber, in a long summer is a heavy feeder, so some gardeners recommend to fertilize once a week! A small fruited, small leaved patio type container cucumber may need little to no feeding.

Since Cucumbers are short rooted, be very careful if you dig in fertilizer or compost. Dig only on one side so as not to break off all the tiny surface feeder roots. Better to add a 1″ layer of compost, some worm castings if you have them, in the planting basin, cover with 1″ of straw and water well. Foliar feeding mixed teas feeds the whole plant with no harm to the roots at all! Cucumbers are quite susceptible to mildews so do the Mildew Mix as well – Powdered Milk, Baking Soda, Aspirin, Soap – add liquid fertilizer if you like, maybe fish/kelp emulsion. Do both the compost and foliar feeding – alternate the Tea with the Mildew Mix every other week or so!

For cucumbers, straw mulch might slow cucumber beetle movement from one plant to another! Plus, it is great shelter for wolf spiders, daddy long legs and other predators. The more spidies the more healthy your garden!x

Exotic Eggplant

Eggplant Purple Long Shiny Harvest Basket

Those eggplant beauties need extra compost and a bit of well-rotted manure at planting time. Dig it in! Apply a general purpose fertilizer in the spring when you till the soil. Add additional applications every three to four weeks. Side dress frequently, especially when the plant begins to bloom. Or sidedress with a Nitrogen fertilizer when the plants are half grown and again immediately after harvest of the first fruits. Or, depending on your soil, feed your eggplants 3 weeks after planting and at blossom set. Given sufficient moisture and good food, eggplant thrives in the heat of summer!

Epsom Salts, Sulfur, is 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 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.

Sulfur, a key element in plant growth, is critical to production of vitamins, amino acids (therefore protein), and enzymes. Sulfur is probably the oldest known pesticide in current use. It can be used for disease control (e.g., powdery mildews, rusts, leaf blights, and fruit rots), and pests like mites, psyllids and thrips. Sulfur is nontoxic to mammals, but may irritate skin or especially eyes. CAUTIONS! Sulfur has the potential to damage plants in hot (90°F and above), dry weather. It is also incompatible with other pesticides. Do not use sulfur within 20 to 30 days on plants where spray oils have been applied; it reacts with the oils to make a more phytotoxic combination.

This mix is super for tomatoes, eggplant, peppers and roses!x

Cut & Come Again Lettuce is a hard working plant!

Lettuces Tasty Varieties, Edible Flowers

It likes water and manure! Regularly. Water just about every day, even twice a day on the hottest or hot windy summer days. Hand scratch in some 1/2″ deep grooves, with one of those little 3 prong scratcher tools, drizzle chicken manure into the grooves, cover back up and water gently. If your lettuce is planted densely that’s going to be a little challenge. A Tea Mix might work better for you. Use the spout of your watering can and get it under the leaves so the soil is moistened. DO NOT do a foliar application of any tea mix that has animal poo in it on any plant you eat the leaves of! If you have space between your plants, and no fish loving predators like raccoons, a fish emulsion/kelp feed is good – just keep it off the leaves.

Feed three weeks after germination, or transplant.
Loose-leaf after second and third cuttings for cut-and-come again crops.
If head lettuce, when the head starts forming.x

Luscious Melons

May is for planting Melons for eating all SUMMER! Goldfarb & Page-Mann Regional Fruition Seeds - Juicy Watermelon!

Melons are a big plant, big leaves, big fruits, on a long vine! Or you may be doing mini container varieties.

Before planting large melon varieties, add in a little extra compost, and leaf mold, some well rotted manure, cow manure if you can get it.

Fertilize big melons every two to three weeks before blooming starts, using an all-purpose 5-5-5 fertilizer. If you are using mulch, pull it back, sprinkle on some worm castings and add several inches of compost to root areas monthly. Put the mulch back and water it in. It’s like giving your plant compost/worm tea as the water and compost/worm juice drizzle down into your soil! Better yet is 2 to 3 days before you sidedress, make a mixed tea sans compost! When the tea is ready, put some spade fork holes in the root zone around your plant. Fill the holes with compost/castings. Foliar feed the tea to your plant and pour tea into the spade fork holes! Of course, the very best is to do both – layers of compost and castings plus the tea and spade fork holes!! Especially sidedress melons when blooming starts and every 6 weeks after.

Another method is to feed when they begin to run; again a week after blossom set; again three weeks later. This probably works well for mini melons.

Once the first fruit ripens, stop all watering. Too much water at ripening time dilutes the fruit’s sugars and ruins the sweet flavor. The melons don’t need the water because they develop a deep root system soon after they start to flower. This means you stop fertilizing just before then. Your plants need soil moisture so their roots can take up nutrients, so there is no point in fertilizing after you stop watering.

Peppers Varieties - Burgundy Bell, Yellow Monsters, Fish, HOT Chile Numex TwilightFabulous Peppers!

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 if you are in Santa Barbara area. 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 quite 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. See Eggplant above

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 near-the-surface lateral feeder 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.

At least, feed at three weeks after transplant; again after first fruit set.x

Super Squash

Zucchini Costata Romanesco Kelly Armful Harvest Annie's AnnualsAnother vining plant, like melons, huge leaves and vine, or patio minis! Big squash plants have the biggest leaves in the garden. They aren’t shy about growing 30′ or more!

Summer – Soft, Zucchini types, Chilacayote

We all know how prolific Zucchini is! That is a hard working plant! Some varieties make more fruit than others. Costata Romanesco, in the image, makes a zuke at every leaf join! Huge Chilacayote vines don’t quit! Even patio container varieties work their little hearts out!

Feed them when plants are about 6 inches tall; again when they bloom. That’s standard, but later in the season, if you still want more fruit, feed them again. If you are so tired of summer squash, never mind.

Like Cucumbers and Melons, summer and winter squash are also  susceptible to mildew, so do the Mildew Mix  for them too – Powdered Milk, Baking Soda, Aspirin, Soap – add liquid fertilizer if you like, maybe fish/kelp emulsion. Alternate the Tea with the Mildew Mix every other week or so!

See also Cucumbers and Melons above

Winter – Hard, Butternut, Acorn, Pumpkins

Give them a fat start with soil amended with well-rotted manure and compost prior to planting. These babies run all summer long, first making the dense fruits, then hardening the fruits. A healthy plant will make a lot of fruits, an ample supply for all winter long!

Feed them when the vine starts to run; again at blossom set.

Strawberries

Sidedressing Strawberries Tricia Peaceful Valley Farm Supply

Perfectly adorable image by Tricia at Peaceful Valley Farm Supply

And that’s true! At Pilgrim Terrace Community Garden we had a first time gardener that fed exactly that mix to his strawberries every 2 weeks and he was so proud to tell us he was harvesting strawberries by the shoebox full! His patch was not so big, but it was prolific with good sized berries! He later went on to sell his fine famed strawberries at Farmers’ Markets!

Juicy Luscious TOMATO!
Tomatoes

Another heavy feeder, making zillions of tomatoes! If your plant is indeterminate, it will make fruit all summer long!

Before planting add plenty of well-rotted manure/compost.

AFTER planting, add a weak solution of complete fertilizer or fish emulsion to the soil around them. Continue to feed them two to three weeks after transplant; blossom time, again before first picking; again two weeks after first picking. Blossom time and after, go light on nitrogen or you will have a lot of leaf, no fruit!

Lengthwise curled spotted leaves? Wilts or blights? Foliar feed with Tea Mix!!! When plant surfaces are occupied by beneficial microbes, there simply is no room for pathogens! The plant will suffer little or no blight, mold, fungus or wilt! That’s a huge claim! But even if it doesn’t entirely work, your plant will likely have a much improved existence for a longer period of time. Beneficial microbes compete with disease causing microbes. Go tigers! The live microbes enhance your soil and in turn, up the immune system of your plants.

If your plant is diseased or pest infested, you may need to apply your mixed tea every five to seven days. Otherwise, make your tea applications every two weeks until your plants start to flower. We want our plants to make fruit then, not foliage!

This Table will help you save time! See at a glance which plants to feed at the same time with the same food. Copy and print, cover with clear waterproof tape, put it on your tool bucket for quick reference! See timing details above, plant by plant!

Summer Veggies Feeding.jpg

With any foliar feeds remember to add that 1/2 teaspoon of dish soap, surfactant, so the feed will ‘stick’ to your plant!

Stand back and take a look at your garden. See who’s the slowest, behind in production, lacks perk, and who looks vibrant, reaching for the sky! Grab a barrow of compost, make a super tea mix, go for the gusto! You could even note your feed date, then mark down about when to do it again!

Here’s to a super plentiful and most joyful summer ever!

Compost Tea Brew for Seedlings

Some of you are pros, literally, at making teas, others of us have never done it before, but interested, even willing to give it a try.

Why? Why make teas at all? Isn’t good soil enough? If you are just making compost tea, with compost you are already using in your garden, you may not notice much results. Every time you water, aren’t you making compost tea in place anyway?! But if you make a more diverse tea, with a lot of different ingredients, and it is made just right producing a lot of microbes, you are likely to get superb results! Research shows foliar feeding is more effective than soil drenching.

A lot of summer plants are what are called ‘heavy feeders.’ They are doing business 24/7 for several months using that soil right where they are at. They can’t go walkabout seeking new soil. Plants that produce leaf crops, lettuces, chard, kale, are using up soil nutrients just as fast as they can! Plants that produce a lot of crop, tomatoes, cucumbers, squash, are feeding a big plant, foliage and fruits! Teas are a microbial inoculant that gives them a boost from leaf to root!

Teas offer increased nutrient availability!

Teas are a high grade fertilizer full of nutrients and minerals! The tea’s chelated micronutrients are easy for plants to absorb. The teas will never burn your plants. You can easily make them yourself from your own materials. You know exactly what’s in it. No chemicals, and they don’t add salt that commercial fertilizers can add to your soil. DIY! Save money!

Marvelously, tea microbes degrade toxic pesticides and other chemicals! Much better for beneficial insects, wildlife, plants, soil and humans. Your soil will come alive again as the organisms start thriving. Your soil will have greater water holding capacity, a resiliency, the aeration it needs from burrowing soil creatures.

Nutrients! Black liquid gold can feed your plants through their roots and their leaves. The beneficial microbes are fast acting and quickly absorbed. This whole plant treatment increases plant growth – more and bigger blooms, bigger size fruits and yields. The microbes produce plant growth hormones; mineralize a plant’s available nutrients, and fix nitrogen in the plant for optimal use.

Suppress diseases! When plant surfaces are occupied by beneficial microbes, there simply is no room for pathogens! The plant will suffer little or no blight, mold, fungus or wilt! That’s a huge claim! But even if it doesn’t entirely work, your plant will likely have a much improved existence for a longer period of time. Beneficial microbes compete with disease causing microbes. Go tigers! The live microbes enhance your soil and in turn, up the immune system of your plants. Your plants are healthier, more stress-tolerant.

Communi-Tea Make your own Compost Tea!

Making teas is fairly new, but is here to stay! Nowadays we know more about microbe power, soil and plant structures and processes. Researchers have determined exacting and scientific ways to brew teas, brewing equipment is available at garden centers or on the internet. Some garden centers are brewing in large batches so customers can conveniently draw-off what they need by the gallon!

There are many tea making methods, from the simplest home bucket method to technical and elaborate brewers with plenty of debate over different ways. Aerobic brewed teas have much higher microbe population densities than extracted teas and for this reason are the teas of choice. A good head of foam and scum on top signifies healthy microbe action! Try out different methods for yourself if you have the time and the gear, and love researching. Whichever you choose, your plants will benefit!

TEA MAKING TIPS

First of all, Temp and Timing matters, especially to the home gardener brewing outside, not using a brewing system. The microbes we want are the most happy at about 75 F, a comfy room temp for us too. Put your brew out of direct sunlight.

Based on Marc Remillards book “Compost Tea Making” temps/time are: 24 hrs @ 75, 36 hrs @70, 42 hrs @ 65 and 48 hrs @ 60. 95 and higher is a no go, just too hot! Your microbes go anaerobic. If you are using a brewing system, you can use an aquarium heater to ensure a constant brew temp especially if ambient is cooler at night. So it helps if night temps are 60 up.

Choose a clean 5 Gallon container or a size that suits your needs

The right water! Rain water is best or let it sit out overnight to allow chemicals to dissipate, or bubble water through an aerator for a minimum of 20 minutes. The chlorine will be released as a gas. Or, add a small amount of powdered ascorbic acid (vitamin C) or humic acids. If you start with chlorinated water it will kill some of your microbes before you get started.

Compost Tea Bucket Straining Painter's Mesh BagStraining your Tea! There’s various thinking on how to strain your tea.

The easiest and simplest is to use a sock, cheesecloth bag, but let the sock be big enough to allow the ingredients you put in it room to move around as it is swished through the water. Clearly those will not accommodate a third of a 5 gallon bucket’s worth of compost plus whatever else you put in. If you will be foliar spraying your tea, sock or pillowcase fibers are too tight to allow the good fungi and nematodes to flow through.

So! Super easy but has a small price, is a painter’s bag, 400 microns, 5 gallon size (they come in different sizes). Perfect! You put it in the container you will use, the elastic top fits over the top of the bucket. When the tea is done you simply lift it out. It has a durable nylon mesh and can be used several times. Add your leftover solids to your compost pile or as a soil topper mulch. Rinse out and dry your bag ASAP.

Or if you already started your brew, just get a 400 micron mesh strainer that fits your bucket, put it over a second bucket, and pour your mix through.

INGREDIENTS! Microbial diversity!

Add Compost

CAUTIONS Unfinished compost or uncomposted manures may contain harmful pathogens and compost that is too old may be nutritionally deficient. COMPOST TEA and MANURE TEA ARE NOT THE SAME THING! Manure teas may be made the same way but are not generally recommended as foliar sprays for veggies and are not as nutritionally well-balanced.

Use well-aged, finished compost The best is good smelling, very dark, broken-down into minute particles like course cornmeal. Dig deep down inside your bin, near the bottom. This is where organic material will be most decomposed and fresh, teeming with life. All you need is a good shovelful or two, maybe a third of the bucket, for a 5-gallon bucket of compost tea.

Add Manure

Cow manure is better than steer manure if you can get it. Chicken manure is good. Less of it does more. Be careful of free horse manure. It can be salty, and if the horses ate pesticide sprayed hay, or the stalls have been sprayed to repel flies, you’ve got toxins. All manures need to be very well composted, except bunny poo, which you can sometimes get free at shelters. Bird guanos do different things. See more soil tips and about quanos. 1 cup of manure may be quite enough. Most importantly, DO NOT foliar feed leaves you will eat, like lettuce, with animal poo brews!

Add Worm Castings! 

In nature, worms are a natural part of soil. In addition to soil nutrients, it’s smart to add worm castings. They speed germination of your seeds, seedlings grow faster. Worm castings help your plant’s immune system, and you have measurably more produce! Plants like strawberries, that tend to attract fungal spores will also benefit. Castings contain anti-fungal chemicals that help kill the spores of black spot and powdery mildew! Growing your own worms and harvesting vibrant fresh castings is ideal, but if you don’t have time, simply buy the best organic castings you can get, fresh and local if possible! More about growing worms! Add 2 cups to your 5 gal bucket.

Compost Tea Seaweed & Herbs - Borage Nettle Comfrey Brew

Seaweed and herbs – Nettles, Comfrey and Borage Tea at Milkwood Permaculture Blog

You can add all kinds of supplements at the same time! Put compost, manure/fish emulsion, worm castings, pond muck, powdered seaweed – 2 tablespoons kelp powder, 2-3 crushed Aspirin, rock dust, alfalfa pellets, chopped nutritious comfrey/borage/tansy leaves all in a bucket together – adding one volume of compost to 4-10 volumes of water. Let them sit overnight, a couple of days, stir a couple times, when you think of it. This turns the tea into a balanced organic fertilizer.

Compost Tea Bottle ComfreyComfrey, a dynamic accumulator, is especially nutritious! Having as much as a 20-30 feet deep root system, it bring minerals and trace nutrients up into its leaves that are unavailable to other plants. It is also the only plant that contains a form of vitamin B12. Mash it in a mortar & pestle, or use a big stone to break it down. That makes it easier to stuff into a stocking or 400 micron mesh bag, and speeds decomposition. Put comfrey in loosely, not too firmly, so the water can circulate around it. Even add a bit of healthy soil! You can make just a comfrey tea alone if that suits your needs. More about comfrey at Nantahala Farm & Garden

How long does it take? Add Sugar or Molasses! Aeration!

It has been shown that adding a simple aquarium pump to the bucket and letting it run to percolate the mixture will increase the potency of the finished mixture, and can be completed in as little as 12 hours to 2 days. If you want a super concentrate, let it brew a week, or more!

Recent research indicates that using some kind of aeration and adding a sugar source (unsulphured molasses works well) results in an excellent product that extracts the maximum number of beneficial organisms. 2 Tablespoons of unsulphured Molasses is good. An aerobic environment favors the aerobic microbes, physically pulls them off the compost and supplies air they need to multiply. This aeration is crucial to the formation of beneficial bacteria and the required fermentation process. It increases the absorption of the water and organisms. For the bucket-brewing method, you must stir the tea a few times during those hours or days it is brewing to aerate it. If you go over the time needed, you need to add more food for the microbes (sugar/molasses), and probably a little more compost.

Caution! Commenter Suburban Hobby Farmer on a compost tea post says: I’ve also read a study from a university extension service that says you shouldn’t use compost tea on indoor seedlings –especially if it has molasses —  because of increased damping off. According to the study, this is true even when watering from the bottom. A 2004 study says a more successful brew intended for seedlings has sufficient aeration, cuts back on the molasses, uses humic acid and kelp additives.

Anaerobic? You waited too long and your tea has gone anaerobic? Your tea should always have an “earthy” odor. If it smells bad, throw away the tea and don’t put it on your garden soil or compost pile.

Wash Your Gear Immediately! Bio-slimes build up inside your brewer or in your 5 gallon bucket. In a brewer this means walls, tubes, small crevices at the bottom. The pressure of hose water isn’t enough to remove it. It may take elbow grease, 3% hydrogen peroxide or a solution of 5% baking soda.

Here I’ve added a few notes to Shelle’s Quickie Recipe and instructions:

  1. 2 cups worm castings [or your choice of ingredients]
  2. 2 tablespoons corn syrup or unsulphured molasses. Molasses feeds the bacterial growth in the brew and also contributes trace elements of iron, manganese, copper and potassium.
  3. 5 gallon bucket
  4. Old pantyhose (no holes), a bag if you are doing soil drenching. Manure tea not recommended for foliar application.
  5. Water (rainwater is best or let it sit out overnight to allow chemicals to dissipate)
  • Put the castings (etc) in the sock and tie it closed
  • Submerge the stocking in water
  • Add the corn syrup and soak for 24 hours, stirring every few hours. Your mix should never be stinky. Like good compost, it should smell earthy.
  • Dilute to a 3 to 1 ratio, use within 48 hours

How long will my tea last? It is best to apply your compost tea immediately; however, it can still produce benefits if applied within 4-6 hours of removing the oxygen source if you are aerating. Remember we are talking about living organisms, trying to keep them in optimum health!

Applying your finished tea!

Diluting your tea. You can use your compost tea full strength on plants that are sickly or not growing well. Otherwise, it usually works well to dilute your tea half and half with de-chlorinated water (you can dechlorinate your water by letting it sit in an open container for a day). Another way of diluting it is until it looks like a slightly dark iced tea for soil/root drenching, weak iced tea for foliar feeding. Of course some teas are stronger than others depending on what’s in it and how much water is used. Work with it to find what works for you.

Will you use it as a soil drench or a foliar application? BOTH!

If using it as a soil drench, dilute or apply it full strength. If your tea is good, you really can’t overdo it! And you don’t need to strain it. But for young, delicate or houseplants try it diluted first. Amazingly, only 5 gallons of compost tea can be diluted to cover approximately one acre of land, and still produce benefits!

Tea to be used as a foliar application you must strain. Use a 400 micrometer mesh or screen. The mesh is big enough to allow the fungi and nematodes to flow through it, while trapping larger particulate matter that will eventually clog your sprayer.

Make sure that the sprayer you are using is designed for compost tea. Many sprayers apply with too much pressure, kill the microbes before they even make it to the plant surface. You need 70 pounds psi or less. Use a smooth, slightly-curved nozzle. With 90 degree bends in the nozzle, the microbes can be damaged. Try to arc or parachute, your application onto the leaves so the microbes land more gently, not head on.

Foliar Feeding - Rose Upturned to Moisten Undersides of LeavesApply with a watering can or a simple garden sprayer. Soak the soil to the dripline. When foliar feeding, be sure to add 1/8 to 1/2 tsp vegetable oil or mild dish-washing liquid per gallon to help it adhere to leaves. Use a watering can with a head that rotates so you can spray both on and under leaves. Minerals and nutrients are absorbed through the leaves and the roots – the WHOLE plant! Apply early in the day, avoid applying in direct sunlight. Ultraviolet (UV) rays kill microbes. If you must apply during sunlight time, do it before 10 am or after 3 pm, when UV rays are weakest.

If you do soil drenching, once you apply it, keep it moist for a few days to a week so the microorganisms have time to settle in, strengthen and multiply! Space out your applications a bit to give them time to get results. If you need a little more mojo deeper in your soil, down where the roots are, use your spade fork, the kind with the short wide tines that are spaced about two inches apart. Push your fork all the way into the soil, wiggle it back and forth to make holes, lift it straight up back out. Pour in your tea. Close the holes. Water a bit the next few days so your soil stays moist below and the organisms can thrive. Your plants will thrive as the root zone is so kindly treated!

When, How often?

Why wait until your plants are in the ground to add teas?! Start feeding your soil soonest! If you have your plant placements in mind, be sure to invest your teas out to the anticipated dripline so feeder roots will get some.

Make your tea applications every two weeks until your plants start to bud. We want our plants to make fruit, not foliage then! Some suggest to apply your tea at least four times per year, 1x spring, 2x summer, 1x fall. If you are trying to overcome disease, you may need to apply compost tea every five to seven days. If your soils have ever been sprayed with pesticides or otherwise compromised, apply more often.

Teas are perfect for container gardens, right?! You can buy ready made tea bags. You can buy Tea! No digging, just feeding.

Some tea making techniques are purposely biased toward bacterial, fungal or neutral predominance. It is speculated that one day we can selectively make teas focused to prevent/heal certain plant diseases or upset pest cycles, preventing infestations, and we are already making super teas to inoculate specific crops for super health and production. Eric in Denver says: ‘Now is our chance to get in on the ground floor of this exciting new science. Get a microscope (400x), learn to identify the main types of soil organisms, refine your brewing techniques, and set aside a place in your garden for experiments. It sounds much harder than it actually is, and there is plenty of work to be done.’

As of early 2011, there was very little evidence that proved the benefits of aerated compost teas; non-aerated teas seemed to fare a little better. That’s similar results as whether to turn compost or not. Turned compost processes faster, but unturned compost is higher in nitrogen! In the Journal of Plant Pathology 2015, Effect of Aerated Compost Tea on the Growth Promotion of Lettuce, Soybean, and Sweet Corn in Organic Cultivation, four types of compost were brewed and then the available nitrogen was determined, as well as the density of microbial communities, along with their effect on plant growth characteristics. Across the board it was shown that aerating compost tea released more nutrients, increased microbial counts, and helped plants grow!

Some practical points: When your tea hits the dirt, the water near the surface remains aerobic sustaining the aerobic species in the tea, and the water that soaks deeper becomes anaerobic sustaining those species. In other words, the soil microbe stratification remains the same as nature makes it. If you apply tea to your soil, made with the same compost you grow with, you are making extra work for yourself! But if you add biodiverse amendments to your tea, it supplies an array of tasty ingredients your compost likely doesn’t have. Compost supplies the organic matter that tea doesn’t supply, so it is critical in and of itself, plus it has many times more nutrients than a diluted tea. But teas are great for potted plants and lawns! And if you foliar feed your veggie plants, the uptake is greater and works within an hour!!! So think through why and how you will use teas and make them accordingly!

Here’s to a blessed summer of happy plants and abundant harvests!

Please protect our birds - they are wonderful helpers in the garden!Birds are wonderful for our gardens!  They eat seeds then deposit them randomly, mini fertilizations; we get amazing volunteers!  They eat all kinds of insects, keep infestations from happening or reduce them.  They sometimes scratch up the topsoil a tad, allowing nutrients to seep in.  Personally, I enjoy their chatter and just seeing them.

This just in from Santa Barbara Organic Garden Club:

Protect birds from window crashes….

Sometimes you can find decals for this purpose at feed stores (La Cumbre Feed or Island Feed  & Seed in the Santa Barbara/Goleta area), or go online:

http://www.amazon.com/Maple-Leaf-Window-Decal-Save-Birds/dp/B001OE3JMW

Also, let windows get dirty and stay dirty. Or clean part of window and leave an X unwashed.

The writer says: We are stunned at the number of birds (new species we haven’t seen before) in our garden habitat. Take a look at today’s bird column in the [Santa Barbara] News-Press, explains what is going on. We NEED to support bird populations, as they are increasingly under stress.

Birds are very thirsty. Please ask your blog readers to add water to their garden, deck, patio, etc. Just a slow drip from a water hose, slightly propped up on a rock or over your favorite water thirsty plant, will be  helpful.  [If you leave a dish or pan of water, please use low sloped shallow items, put a flat stick for lizards and other littles to climb out on in case they accidentally go for a swim!]  Thank you!!!!

Mediterranean Understory & Guild Plants for Food Forests – Part 2

Please SEE Part 1 before you read this list!


Here is what a young Food Forest can look like in a part of your urban yard!

Linda’s List here is intended for a Mediterranean climate like coastal Southern California has, one of only 5 in the world. The list in your area may be different. Check out your local gardeners’ successes, check with your local nursery. This list is not tree specific yet. We’re working on that!

More than a list of plants, Linda’s List gives tips for good growing, eating, and usage!
____________________________________________________________________

Once our fruit trees are planted in their water-saving basins in a budding Mediterranean food forest, it’s now time to think about what else to plant in these usually moist wells and swales. Or up the trees? Or nearby? We need these companion plants to increase our food and medicine yield, and also to enrich the soil, provide habitat, pull up minerals and other nutrients from deep in the earth, draw nitrogen from the air and bring it into the soil, attract beneficial insects to control pests, create shade for delicate roots — and to provide beauty, a critical psychological and spiritual yield in every garden.

Thanks to the members of the Permaculture Guild of Santa Barbara and the Santa Barbara Organic Garden Club for their ideas and input. Additions and corrections are welcome.  Please email lbuzzell@aol.com. Especially welcome would be input on what plants do best under specific fruit trees – so far I don’t have much information on that.

BERRIES
Blueberry. To grow well here, they need acid soil, so a container is often the best solution, since Santa Barbara soil and water tend to be alkaline. One gardener we know waters hers with a very dilute solution of white vinegar, plus puts pine needles, coffee grounds around the plant. Best in Mediterranean climates are the low-chill varieties like ‘Misty,”O’Neal,’ ‘Sharpblue’
Cane berries. Upright cane berries are fun to pop in here and there as understory plants and they take some shade. But we found out the hard way that you probably don’t want to put in sprawling, thorny berries (especially blackberry) that sucker underground – they pop up all over the yard and are hard to eradicate. When we buy new berries we limit ourselves to thornless varieties and our current favorites are ‘Navajo’ and ‘Apache,’ although the thorny varieties that still linger in our garden – and will probably be there for hundreds of years as they’re ineradicable – taste best. So we live with them and enjoy the berries.
Elderberry. Shrub. There is a California native variety. Produces edible fragrant white flowers (used to make elderberry syrup and wine) and edible small blue berries that the birds love. Ripe berries are safe to eat but leaves, twigs, branches, seeds and roots are toxic. Has medicinal uses. We use our elderberry as a sacrificial plant attracting birds away from other fruit trees.
Lemonade Berry (native). Rhus integrifolia. Can also control erosion.

BULBS AND ROOT CROPS
Placement of these may take special care, as you don’t want to plant them too close to delicate tree roots.
Carrots
Edible canna. Canna edulis –Achira. Flowers are smaller than most cannas and the root is edible, can be chopped and sautéed like potato.
Onions
Potato and sweet potato

EDIBLE FLOWERS (note: most fruit trees, veggies and herbs also have edible flowers. Always triple check the safety of any flower before eating!
Daylilies. Hemerocallis species. Buds are used in Chinese stir fry, Petals in salad.
Nasturtium (flowers, young leaves and buds that may be pickled like capers) Let the plants die back in place. They will reseed and form a straw mulch.
Roses (yield petals for salads, sandwiches, syrups, desserts; rose hips for tea, syrups, jam)
Scarlet runner bean
Scented geranium

HERBS (most have edible flowers in addition to other uses)
Borage
Chili peppers, including tree chili
Cilantro
Garlic
Italian parsley
Lavender
Lemon balm
Lemon verbena. A drought tolerant shrub with delicious leaves for tea.
Mint. Some fear its vigorous, spreading roots, but we welcome it into drier areas as ground cover, autumn bee food and a source of fresh leaves for cooking and tea.
Mustard (young leaves can be stir fried, flowers are edible, plus seeds for making mustard)
Pineapple sage (leaves and flowers make delicious herbal tea)
Oregano
Rosemary
Sage

SHRUBS/Understory trees
Guava. Psidium Tropical shrubs native to Mexico, Central and South America that yield white, yellow or pink fruit. Not to be confused with Pineapple Guava (Feijoa) Psidium guajava (apple guava) is one tasty variety. Also try lemon guava and strawberry guava.

VEGGIES (there’s no way to name them all – it’s fun to experiment to see what likes the soil under and around your fruit trees. Our favorites are those that overwinter and/or reseed themselves)
Artichokes. Plant away from tree roots, in baskets as the gophers love them.
Brassicas like broccoli, kale, collard greens.
Chard.
Dandelions. Leaves are great in salads and so good for us. Small birds like the seed heads.
Fava beans and other beans.
New Zealand spinach.

VINES
We often forget about vertical space in the garden, but it’s nice to increase your yield by growing edible vines up fruit trees, on walls and over arbors, fences and hedges.
Grapes. Note: the Permaculture Guild of Santa Barbara has a separate list of recommended table and wine grapes for our area. Contact lbuzzell@aol.com for details
Passion Fruit. A garden member says “mine is simply rampant, productive and trouble-free; gets little to no supplemental water.” The juice can be used to make a spectacular salad dressing (served at Los Arroyos on Coast Village Road in their tropical salad).

MISCELLANEOUS
Bamboo. Use clumping instead of running kinds to avoid it taking over your garden. Bamboo shoots are a delicacy in Asia.
Pepino melon.
Sacrificial plants. In permaculture designs we often plant trees, shrubs and other plants that are nitrogen-accumulators, “nurse” plants or fruit-providers for animals that might otherwise eat our crops. When they have performed their function, we “chop and drop” them around our fruit trees as a nutritious mulch.
Yucca. We’ve read that yucca yields edible fruit and flower buds. Anyone have more info on this?

BENEFICIAL ATTRACTORS AND NUTRIENT ACCUMULATORS
Ceanothus. Shrubs and ground covers that fix nitrogen in the soil.
Salvia, ornamental. These are treasures in the Mediterranean forest garden.
Tagetes lemmonii. Golden color is lovely in fall.

GROUND COVER
Easy-to-grow succulents can provide temporary ground cover for delicate roots. They can act as a living mulch until other plants take over that function. This crop is often free, as gardeners who have ground-cover sedums always have too many and are glad to share.
Pelargoniums and lantana are other easy, colorful ground cover that can be removed as needed.

#1 Home Permaculture book in the world for seven years!

Per PatternLiteracy.com, Toby Hemenway’s home site, Gaia’s Garden has been the best-selling permaculture book in the world for the last 7 years. The enlarged, updated 2nd edition is the winner of the 2011 Nautilus Gold Medal Award.

The first edition of Gaia’s Garden sparked the imagination of America’s home gardeners, introducing permaculture’s central message: Working with nature, not against her, results in more beautiful, abundant, and forgiving gardens. This extensively revised and expanded second edition broadens the reach and depth of the permaculture approach for urban and suburban growers.

Treat yourself and your land to this incredibly efficient way of gardening. Wisely use ALL the space available to you in a good way. Nature is the Master Gardener – follow her lead.
