Soil No Till Lasagna Compost in Place, Sheet Mulching,

No Till Gardening aka Lasagna Gardening… Beds are finished. Push aside grass clippings to plant seeds or seedlings. Read the story, get the details! Start making living soil asap! 

Grow Green Manure  SoCal’s two best starting times are October 1st for mid January bare root plantings, and January 1 for April heat lover plantings! Adjust as you need for your own timing needs. Plant legumes for Nitrogen, oats to loosen the soil down deep. It takes two to three months depending on which plants you choose to grow. If bell beans are one of your choices in a mix, when it starts to bloom, chop your green manure down. Let it lay on top of the soil 2 to 3 weeks, keeping it moist. Add whatever other amendments you choose and turn it all under. Let it sit 2 to 3 weeks more so the soil organisms can decompose it and build soil structure. If you have heavy clay soil or are in a drought or dry, windy area, add Sphagnum Peat Moss to both loosen your soil and increase water holding capacity and more compost too. Probably the fluffy store bought compost with a lot of texture will do the best. Let the mix sit until you no longer see the green ingredients. Keep it moist, not muddy, so the soil organisms will work all the way to the top. See more: Cover Crops  Living Mulch

Make Compost!

No time for Green Manure? First week of January might be the latest time you want to start growing your green manure so you can plant late March, first two weeks of April. So if you won’t be planting by then, add your home grown organic compost or the best you can buy that has worm castings (especially for planting seeds – speeds germination), mycorrhizal fungi for spring planting, some peat to help make humus to keep your soil loose.

Some nurseries, especially locals that depend on your business, are quite trustworthy about what they stock for you. Box stores, nurseries that sell for volume, may just want you and it out the door. Really take a good look at that ingredients list. If there is no list, you likely aren’t getting a very whole food for your veggies. Look at what is in that compost bag when you open it. If there are chunks of recognizable materials, you need to find out if the compost has been nitrogen stabilized – they’ve added enough nitrogen to balance the carbon. Otherwise, Nitrogen required for decomposition is robbed from your plants. It should have no ammonia smell that indicates immature compost that might damage your plants. The only smell you want coming from that bag is for it to be like the forest floor, sweet and earthy.

In SoCal drought times, or garden in a dry, windy area, compost is the single most thing you can do for your soil to add water holding capacity! Sphagnum Peat Moss or coir can be added, but not too much peat because it can make your soil slightly acidic. If you have heavy clay soil, they will also loosen your soil.

Compost is totally easy to make. There are many methods, but the simplest and fastest technique has always been putting fine chopped kitchen waste and healthy garden trim in mini 6 to 8″ deep trenches or areas! Soil organisms are at work and it completely disappears in less than 2 weeks, and you don’t have to move it, it’s already in place and ready to plant in! If the soil there is too dense, you can add store bought compost that has a little fluff, more water holding capacity.

If you need to collect a little compost in place, there are no open trenching spaces available right now, you can make layered compost in a compost enclosure or pit if you wish. 1″ green/wet to 2″ brown dry. You can turn it or not. Research shows not turning it has more Nitrogen. There are many different compost devices. You can use one or just make a pile wherever it makes sense, but do put it in the sun and keep it slightly moist so it stays active and you actually get some compost! Compost making methods!

Tasty soil is loaded with nutrients! What you put in your compost makes a difference. High quality organic kitchen scraps sure beats cardboard and newspaper. Same thing with your worms. Newspaper isn’t exactly food, doesn’t occur in nature. As is said, ‘You are what your food eats.’ Give your compost the best you have or can get. Prevail on your neighbors or family to save their waste for your compost or to feed your worms. Make it easy for them to do the process. Some will deliver it to you because they believe in it and want to help. You may have to make a pickup from others.

No till, no dig, gardening a.k.a. Lasagna Gardening ~ Another way to Compost!

You can do this on top of your lawn, or do a raised bed in the garden you already have! A word to the wise! First, install gopher protection.

If you have the time and materials, composting in place, sheet mulching, has the single most advantage of not having to haul anything anywhere once done! It’s already right where you want it! Lay down your compost materials. Put the ones that would act like tea at the top so when the pile is watered that good stuff drizzles down. The smaller the bits, the faster the decomposition. Chop ’em up!

Depending on your materials you may choose to turn the pile a couple times to blend and mix the materials in the layers. Rather than using a shovel, a spade fork or pitchfork might work, better. If you have them, add worms after all turning is done so they won’t be injured. The worms will add their castings for you! Possibly, ‘inoculate’ your pile with a wee bit of already processing compost or top rate soil that has working soil organisms in it. Know that an 18″ pile will soon become a 9″ pile, so don’t be afraid to build high!

If you want it sooner, cover and ‘cook’ it with black plastic for 6 weeks results when temps are high enough. Worms will be ok. They will go to the bottom of the pile. Depending on availability and preferences, what you layer on will undoubtedly vary from someone else’s project, but your garden bed is made! Now you wait. Let it sit. The hard work is at the front, the rest is ‘low maintenance!’ Done ‘right’ you have less weeds and it needs less water! Read the story that goes with the image above – get more ideas and all the details!

Another terrific way to make a sustainable pile is to do it Hugelkultur style! Your pile starts with logs! The logs and branches soak up water and hold it, so less water to none is needed after the first year. The right hardwood logs will give your plants steady nutrition for 20 or more years! You can do this with many variables depending on materials available and your needs – from containers to the hill method! See more and see how!

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 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. Different bird guanos do different things per NPK, but mainly they take a long time in the ground before they become available to your plant. Study up on them before applying them.

Worm Castings! 

In nature, worms are a natural part of moist 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, local if possible, castings you can get! More about growing worms!

The ideal ratio, depending on your soil, is 25% castings. You can see that is a lot of castings if you have a 10X20 foot area. Use your precious castings wisely. Use them in seed beds, planting holes, around ailing plants, or heavy producers.

The worms used for making castings are surface feeders, red wigglers. If you trench your compost, add some of them. If you do sheet composting – composting in place, set up a no-dig Lasagna Garden, install some worms! If you don’t turn your compost, add a handful of worms to your compost pile and keep the pile moist. If you turn your compost, don’t add them – you could injure or kill them. In dry times cover composting ground areas with mulch so the compost will be dark and moist, and your worms safe from birds. If your pile is moist enough, cover it before rains. Shade slows things down; put your compost in the sun!

Compost Tea Bu's Brew Biodynamic Malibu BagTeas offer increased nutrient availability!

First, 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. Making tea outdoors generally doesn’t work in winter, even in SoCal. So if you can, make it indoors. If you need to transport it, you may need to put it in smaller covered containers.

Why wait until your plants are in the ground to add teas?! Start feeding your soil soonest! Mix ’em up. Put compost, manure/fish emulsion, castings, 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. Get a spade fork, the kind with the short wide tines. Push it all the way into the soil, wiggle it back and forth to make holes, lift it straight up back out. Pour in your tea. Push soil in the holes. Your plants will thrive!

If you are foliar feeding, put your ingredients in a stocking, sock, or bag. Let the ingredients settle or strain it so it won’t clog up your gear. Use a watering can with a head that rotates so you can spray both on and under leaves, wetting the whole plant.

About that comfrey. It is especially nutritious! Mash it in a mortar & pestle. That makes it easier to stuff into a stocking, sock or bag, and speeds decomposition. Put the comfrey in loosely, not too firmly, so the water can circulate around it.

Here’s another recipe and instructions from Shelle

  1. 2 cups worm castings [or your choice of ingredients]
  2. 2 tablespoons corn syrup or 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 sock or pantyhose (no holes), a bag
  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

There are many tea making methods, from the simplest like above, to technical and elaborate 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 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 the burrowing of soil creatures.

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.

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

Soil pH

Most veggies do best with slightly alkaline soil but will be ok a little to one side or the other. Definite acidic soil lovers are strawberries, blueberries, cranberries. Composts for camellias, azaleas, are perfect!

Do or Buy!

Three of the main components of top grade soil are ones you can grow/make on your own – green manure, compost, worm castings. Teas you can make from compost and castings. For most urban gardeners it is a trip to the nursery for manures, but you can certainly make your own tea with it! Compost and castings are totally available, some from organic local venders. I emphasize doing your own when possible. You will know what’s in it and it’s 100% fresh and alive!

There is some good ready made stuff you can get. There’s heroic satisfaction in toting those bags on your shoulder or filling the wheelbarrow and rolling it in, almost spilling the load on the way… Digging in your valuable ingredients gives you a feeling of virtue – LOL, worthiness, contributing. And oh how your garden grows!!!

At the same time, lay on your compost, manure, and Sphagnum, any other favorite amendments, and turn it in all at once, blending it with your soil. Castings are usually added separately unless you have enough for the whole area. Reserve some of your castings, compost and manure to make teas. Where you run out of materials, use the tea to help that soil.

A few more tips!

If you have had rain, wait until your soil is not so wet that it sticks to your shovel. If you are digging your amendments in, do minimal digging; leave clumps when you can to maintain soil structure. Disturb soil organisms, worms, the least possible. We want to leave their air and water channels intact so your soil stays aerated and moist. Make beds in your garden that are comfortably reachable without stepping on your soil. Make pathways, either with boards that distribute your weight or lay down straw or other organic material to make a pathway that will decompose and become rich soil for next year’s plantings when you move the path! In other words, don’t compact and crush your fluffy healthy soil!

Soil Building and Care is the single-most important thing you can do for your garden.

Veggies growing in homemade compost!

Compost is the single most best thing you can do for your soil! It feeds your plants, adds water holding capacity, and much more! 

Anytime we have a season change, compost becomes more important. In summer most of us are thinking how can I do it all?! Harvesting takes more time than waiting for the plants to produce. There’s more watering to do in summer. Yet, fall is soon upon us and though making compost takes a wee bit more time, it is so needed to give our plants a good start! In winter, making compost is essential for spring planting!

Here are some possibilities!

There are 3 basic kinds of compost, cold and hot and composting in place.

Of the cold kind….

The kind that finishes the quickest is the kitchen veggie waste that gets chopped vigorously with the shovel every few days, turned and turned again. Small bits decompose faster. The pile is kept moist. The dry brown material in the pile isn’t usually  straw. Straw is hard to chop and takes a long time to decompose. It’s more like leaves, some already chopped, partially decomposed mulch type stuff. The right leaves have nutrient value. See more. With only a couple of turns, this whole process might take two weeks, usually less – even in cooler weather! It’s quick. For quick results it’s also best to put your compost in full sun. Shaded compost usually ends up untened. It’s in an out-of-the-way place, processes so slowly a lot of gardeners forget they ever made the pile. Neglected, the pile literally dies.

In a community garden or a small garden area you might not have space for such a pile. But if it’s a priority you probably will make the space! If you do, and if you want to keep it a bit contained, instead, make a shallow pit and put your ‘pile’ in there. Toss a thin layer of healthy soil over it and turn that in to inoculate your compost with soil organisms. They will speed the decomposition process. A thin layer of soil also keeps flies away and you have no smell. Cover it with a light layer of straw or plastic to keep it from being unsightly to visitors while it is in process. A wire cover over straw lets rain in, so I use a couple plastic bags left from manure. I put a light weight board over my cover and a concrete stepping stone on the board to keep it from blowing away. If it rains, the cover keeps your processing compost from getting too wet. If it’s dry weather, covering keeps it moist. It will decompose better rather than off gas the Nitrogen, dry and die. The cover is instantaneous to remove, then you can have at that pile with gusto! With that kind of pile, you have a fairly steady supply of compost. Most of the time some of it is ready to put here and there.

I am very grateful to three neighbors who give me their green kitchen waste. Since I also grow worms, I ask them to give me only what they imagine a worm could eat. Worms!

Compost Sifting‘Every day I fill the wheelbarrow with rich screened compost. It really smells quite delicious; nutty with a spicy note.’ Sifting your compost is a piece of cake! Grab your wheelbarrow or bucket, get a piece of hardware cloth/hogwire or a nursery plant flat with a smaller weave to it, like in the image, and sift away! You can build a lovely framed sifter or buy great rolling devices. Choose the size opening you want. Or, don’t sift at all. I like a little texture to my compost. 

Have your compost pile handy, nearby, warm in the sun for speedy decomposition! Keep it moist, cover it when it needs it – in hot/dry or rainy weather, turn it! Compost that gets turned regularly often gets raided before it’s completely finished. You can still make out some of what the stuff is that’s there. That works just fine because it finishes quickly, in the ground, at home with all the lovely soil organisms.

If there comes a time when you compost has been sadly neglected, spread the stuff out as a mulch and start over, or let it go and just buy what you need. No shame in that.

Hot Compost is PDF, pretty darn fast!

It can heat up to amazing temps, so hot it makes ash and you cannot put your hands in it without getting burned. You can see it steaming on a winter morning! The point is to kill diseases, pests, weed seeds. Well that almost gets done, because, you see, the heat is in the middle of the pile. So they say turn it so the hot part goes to the outside and the cool part to the inside. That, my friends, is easier said than done. But, at least some of it happens.

Two interesting points here. My cold compost pile gets that hot! Yep, it does. A well-built pile with thin layers will cook quite happily no matter your intention. It’s nature. The other thing is I don’t put diseased plants or seeding weeds in my pile, so I don’t need it to get hot. Sure, some pest eggs probably make it. However, what happens most is veggie seeds sprout when I put the compost in to amend my soil! I swear, I can’t see those seeds when it is compost. It all looks dark and yummy. But lots of times I’m glad that happens! The plants get a terrific start and I get surprises! This year I enjoyed two elegant celery plants that came up about a foot and a half from each other and everyone complimented how beautiful they were, robust, with gorgeous long dark green stalks!

Whether you do hot or cold compost is your choice. I’ve tried it both ways. Sincerely. Got a long thermometer, built cubic yard piles and turned them. Now I have cold compost and turn it. No way around that turning if you want results sooner than later. It doesn’t matter what size I build it. I’ve seen 1 cubic foot piles heat up just fine! If it gets hot, it’s hot. If it doesn’t that’s fine with me. Taking care of it, turning, keeping it moist, making thin layers gets the job done. The layers are more a measuring device – 1 dry to 2 wet. Once they are in, mix up the material so the straw is moistened and the wet just doesn’t make a mass. My friend who chops and turns his with vigor gets much faster results, and I may take that up too.

Composting in place

No dig composting in place is an age old technique more recently called Lasagna Gardening. It takes some prep time, that is often done with a group of friends, but once that is done, you’re home free! There’s no turning, no carrying finished compost about because it is already where you want it! Materials may take longer to decompose. It is a cold pile, but if your pile is directly on the earth, soil organisms happily munching makes things happen quickly. It takes a lot of materials to start depending on the size you want your garden to be. You can start with a small area, add more later.

The beauty is it can be done on top of a lawn to form a raised bed, with or without a box border. If you have lawn where you want to plant, peel back the lawn or not, lay down cardboard or newspaper to kill off the lawn, prevent it growing back, up into your bed. If you choose cardboard, water a LOT to soak that cardboard. Layer to your heart’s content until you run out of materials. You can make beds 18″ high to start. They will settle a lot. That 18″ can easily become 9″ in two or three days in warm weather! You can plant instantly! Just pull back a planting hole, add some ready or nursery-bought compost and any other amendments right for your plant, and plant! Your amazing ‘lasagna’ will decompose and make beautiful soil without you doing a thing more! Add more materials as you acquire them to any spots you want to build up or if you want more compost or a bigger or another bed!

If you are doing composting in place while gardening, you just put on the layers, between the plants or down a row, with the materials you have on hand until you run out. The smaller the chop, the pieces, the faster the decomp. Keep them moist so they will decompose faster.

Trench it and forget it! Trenching has always been the simplest technique of all! It’s a super simple way of putting chopped veggie kitchen wastes to work. Dig, pull back a 6″ trench, no deeper. Soil organisms live at the top. Put your kitchen waste in the trench, grab the shovel and vigorously chop the waste into fine pieces. If you don’t feel like chopping it, don’t! Put in the stuff, cover with some of the soil you pulled back. Turn that a couple times to mix in soil organisms to speed the decomp process, cover with the remaining soil and forget it. Period. Done. A week later you can dig in that area and find no trace of it. Soil organisms are intelligent and born hungry.

I combine trenching and a pit. If I have a spot needing compost, I trench it there. If there are no spots needing it right now, I put it in the pit and hold it until a spot needs it or a plant needs sidedressing (feeding mid season). In that case, in summer I also at a bit of manure or if it’s SoCal winter time, a little fish emulsion for easy and quick uptake.

NOTE! Compost you make isn’t the same as manure, nor nursery bought bagged compost. When you trench, you can add those at the same time if you wish. Manure is good ole down home stinky poopy stuff high in Nitrogen. You can also plant cover crops, living mulch, green manure for Nitrogen. You plant different areas to restore your soil, or in SoCal winter to make good soil for spring planting. Your soil also needs water holding capacity from bulk – what is called forest materials in nursery compost bags. Bagged nursery compost is fluffy. Air space. Your soil needs that too. Kitchen waste compost doesn’t have that. I buy bags of nursery compost – bulk and chicken manure – Nitrogen, as well and add them, sometimes to an area, definitely to my planting holes. Plants uptake a lot of their nutrition from tiny lateral feeder roots that often grow beyond the dripline of your plant, so if you can, do a whole area. Add special amendments to your planting hole. Make that planting hole a bit larger than you have been doing? Sometimes it depends on your budget how much materials you have available. Planting cover crops is cheaper, but it takes longer…

If you have massive amounts of stuff to compost, the fastest way of all, record time, is to use maggots! Cities use them and sell the compost! See all about it!

Hugelkultur Sepp Holzer Diagram Cross Section

Hugelkultur is a long term choice. Hugelkultur, hill mound, is the quintessential sustainable variation of ‘composting’ in place. It can be above and/or below ground and takes a lot more energy to start but what a payoff! Get some big logs, branches. If you are doing it above ground, lay two logs closely side by side, put a lot of bigger to smaller branches between them, then go for it! Woods that work best are alders, apple, aspen, birch, cottonwood, maple, oak, poplar, willow (make sure it is dead or it will sprout). Add leaves, grass clippings, straw, cardboard, petroleum-free newspaper, manure, compost or whatever other biomass you have available. Add some red wiggler casting worms if you have them. As possible add your materials in thin 1/2 to 1″ layers, dry, wet, dry, wet until the area is filled. Lay a third log on top of them and if you have sod you peeled up, lay it on top of the whole pile upside down and do it again! Top the turf with grass clippings, seaweed, compost, aged manure, straw, green leaves, mulch, etc. Top that with soil and plant your veggies! If you did it right, you end up with a steep sided tall pyramid pile and veggies planted at easy picking heights. See a LOT more and example variations at permaculture, practical solutions for self-reliance.

Raised bed Hugelkultur Lasagna Combo Buckman StyleIf you are starting a raised Hugelkultur bed, dig down about a foot or more, lay in the big logs, big branches around them, smaller branches on top, layer as above to the height you want, allowing for settling. The difference is that this is a flat top raised bed. You can also dig deeper and make the top of the bed flush with your soil! Also, you can do terracing with a Hugelkultur substructure.

Container gardeners you can do your own mini Hugelkultur version as well. A 1/2 beer barrel, a five gallon can, kid’s swimming pool, whatever you have, can be repurposed! Just be sure there are drainage holes. Double purpose your container by making it a self-watering system as well!

Hugelkultur is an excellent long term sustainable choice!

~ The heat from decomposition gives your plants a terrific early start or extends your growing season. You do need to be careful of freezes if you live in a cold area.
~ The right hardwood logs will give your plants steady nutrition for 20 or more years!
~ If you do the above ground version, you have more planting space because it is tall and vertical!
~ Nearby fruit trees are also fed.
~ The logs and branches soak up water and hold it, so less water to none is needed after the first year.

More clever tips!

  1. At intervals, near the center of your compost pile, place handfuls of old compost or fresh rich soil, as an infusion, an inoculant of soil making organisms.
  2. In dry SoCal, I cover my compost pile to keep it from drying out, and I never need to water it.
  3. When cold composting and composting in place, add red wriggler worms to chomp up materials. They add worm castings that help your plants’ immune systems and uptake of nutrients. If you will be turning the compost, kindly use a pitchfork so there will be the least damage to your worms.
  4. Be smart, add herbs! Penny Woodward says: ‘Regular handfuls of chamomile, dandelion and yarrow leaves and flowers will all speed up decomposition of the compost with YARROW being the most effective. Yarrow also adds copper, nitrates, phosphates and potash while chamomile adds calcium and ‘sweetens’ the mixture. Dandelions contribute copper, iron and potash. Nettles are problem weeds but they actually improve the quality of the soil they are growing in and when added to the compost they contribute iron and nitrogen. Tansy adds potassium, which is very important for plant growth while Valerian increases the phosphorus content so essential for good flowers and fruits [but is invasive!]. The most nutritious compost plant is COMFREY and it grows most of the year in SoCal coastal climate. The leaves are rich in potassium, nitrogen, calcium and phosphates. I keep a clump growing next to the compost. It grows like crazy, and I layer on a handful of leaves whenever I throw in kitchen scraps.

Mix it up! Do any version or combo of compost versions that work for you or as you have the materials available to do what you want! Do more than one method at the same time! Super soil is the Number 1 thing you can do for your garden and compost makes the difference! When your compost smells great and you could just about eat it, you know you made it right!

All that said, there are tons of composting devices available. Some work more or less, some work for one person but not another, for various reasons. Google for pros and cons of each one before you purchase. See if you think you will tend it as it needs to be tended, if it suits your needs, your location. Will you need additional tools. Imagine doing the process it requires. Would that really work for you. Worst is you buy and it fails. You can resell it, give it to someone who would be dedicated to the process it needs, donate it to a charity sale, or an organization that needs one. It’s ok.

All that said, if building your own compost isn’t your choice, support your local nursery and get the best from them! Otherwise, have a good dirty time of it!

Mycorrhizal Fungi, the Proof is in the Roots!

Mycorrhizal Fungi increase uptake of nutrients by increasing the surface absorbing area of roots 100 to a 1,000 times!  This is like having way more than a second set of roots!  They work in both natural soil and with fertilizers added, especially phosphorus. P is for  flowering, so increases production.  The fungi also release powerful enzymes into the soil that dissolve hard-to-capture nutrients, such as organic nitrogen, phosphorus, iron and other “tightly bound” soil nutrients.  The extra nutrients can fuel better growth and increase resistance to drought and disease.  Plants in soil with well-established mycorrhizal fungal root systems are better able to survive droughts and transplant shock, and the fungi’s ability to alleviate salt stress is well documented.

Two exceptions to using MF:  1) When the soil already has such ideal nutrient and moisture levels that the plants can scavenge enough on their own.  2) with Brassicas (members of the mustard family), because they do not allow the mycorrhizal fungi to colonize their roots!  Save your time and money!

There is so much more known now due to research the last 40 years!  David D. Douds, Ph.D., a microbiologist with the USDA Agricultural Research Service (ARS), notes that different species of plants have different tendencies toward developing mycorrhizal associations. For example, he has found that leeks greatly benefit from mycorrhizal association in most years, while tomatoes and peppers are more likely to benefit when they are more nutrient-or water-stressed. Brassicas such as turnips and radishes do not form mycorrhizal associations under any conditions.

Recent research shows mycorrhizal plants warn each other when disease or pest infestations occur.  ‘The uninfected ‘receiver’ plants also activated six defense-related genes!’  The infected or infested plant may die, but the others live!

Don’t kill your Mycorrhizal Fungi!

Day to day gardening can degrade and destroy delicate mycorrhizal fungi, and the mycorrhizae-forming potential of your soil.  Not good.  Tilling and hoeing, removal of topsoil, erosion, site preparation, compaction (removes air and damages filaments), fumigation, relentlessly removing weeds, and leaving soils fallow without a deep mulch covering, are some of the activities that can reduce or eliminate these beneficial soil fungi. Scientific studies indicate endo mycorrhizal fungal populations are slow to recolonize, unless there is close access to natural areas that can act as a source of mycorrhizal spores to repopulate the affected area.  Reintroducing mycorrhizal fungi in areas where they have been lost can dramatically improve plant performance with less water and fertilizer and at a reduced cost.

So, for example, if you just dug up an area to install gopher barriers, that area needs some babying, tender repopulating.  And you can see this is a huge reason to do lasagna gardening, or sheet composting.  Put the nutrients, compost on TOP of your soil.  Don’t dig up your soil and destroy the mycorrhizal network and soil structure of the micro herds of soil organisms, or the mini air tunnels earthworms make that let your soil breathe and moisture to soak in!  Don’t be shy!  Pile it all on a foot to 18″ deep!  Remember, that pile will rapidly settle to about 6 to 8″ deep.  For immediate planting, pull some holes open, add a tasty compost, and plant away!

Tips to Help your Mycorrhizal Fungi Flourish!

  • Add fungi!  Sprinkle dry or pour or spray liquid fungi right on the roots as you put in your transplants, except those Brassicas.  Use a core drill or auger and put liquid fungi down into your soil.  Not only does it help veggies, but your turf grass as well!  While you are at it, put in some compost tea in alternate holes to build your soil herds.  You will be amazed at the results from these amendments!
  • If your soil is already high in phosphorus (get a soil test), do not fertilize with a phosphorus-rich amendment, because too high phosphorus levels inhibit development of associations between plants and mycorrhizal fungi. Manures and manure-based composts can be high in phosphorus, so test these amendments before adding them.
  • Minimize digging (especially rototilling), as it can break mycorrhizal hyphae, preventing them from colonizing new plant roots and transporting nutrients.
  • Don’t let your soil dry out!  Cover it deeply with partially composted leaves and other organic material if you aren’t planting there right away.  Plant densely enough that your plants are living mulch.  Or, simply water anyway until you are ready to plant.  If it will be an extended time, best of all is to plant a quick growing soil-feeding cover crop!
  • Grow a diverse mix of plants in your soil for as much of the year as possible, because mycorrhizae need active plant roots in order to develop.
  • If you decide to use mycorrhizal inoculants, look for a company that produces the inoculant in your geographic region.

Elaine Levine suggests techniques to keep your mix diverse:

• Rotate crops each year (as long as there aren’t too many successive brassicas). Crop rotations are vital to mycorrhizal fungus populations because, in addition to providing a continuous succession of root hosts, different crops also tend to favor different species of mycorrhizal fungi.
• Plant a cover crop. In addition to adding organic matter and retaining soil nutrients, the cover crop offers host roots for the mycorrhizal fungi to colonize and helps them proliferate in preparation for your next planting. A good mix of crops above ground is the best way to support a mix of beneficial fungi below ground.
• Lighten up a bit on weed control, because, surprising as this may be, weed roots can also be excellent mycorrhizal hosts.

Santa Clara Master Gardener Elaine Levine says ‘These simple, no-cost steps help keep the soil’s native population of mycorrhizal fungi healthy and diverse, harnessing yet another gift of the natural environment to create a vibrant and abundant garden.’  She’s so right!

TheEarthProject.org says:  Arbuscular mycorrhizal fungi [AMF] is the medium of soil structure, it determines the flow of water, nutrients, and air, directs the pathways of root growth, and opens channels for the movement of soil animals. As the moderator of the microbial community, it determines the metabolic processes of the soil. In other words, the mycorrhizal network is practically synonymous with ecosystem function.

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

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

                            Sheet Compost/Lasagna Garden Layers                           

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

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

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

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

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

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

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

February! SOIL & SEED Month!

Please see February 2010 for tips on aphids/white flies, slugs/snails, gophers, soil, seed starting basics! 

When there are warm days, it is ever so tempting to plant up summer veggies!  Don’t do it.  Not yet.  Start seeds. 

Depending on how much space you have, plant a last round of your very favorite winter crops – lettuces, beets, broccoli, cabbage, carrots, cauliflower, celery, chard, kale, kohlrabi, potatoes, radishes, turnips.  Bare-root asparagus and artichokes.  I forgot to tell you last month, you could start zucchini!  At Pilgrim Terrace Community Garden we had an elder gardener who always started his in January, early February, and had great zucchini way before everyone else!  Other than zuchs, really look at those days to maturity, and add the number of days you expect for harvest duration.  If you plant a long maturing plant that would be harvested for some time, think if you would rather have that space for an early round of a summer veggie you love more.  Choose mildew and disease resistant varieties for your late peas.  

Keep sidedressing your producing plants, protect your tasty lettuces from slugs and snails.  Keep watch for aphids, and, if you disturb your plant and a little cloud of white things fly off, you have white flies.  Spray those little buggers off asap so they don’t spread to your other plants or someone else’s!  Keep up with your harvesting.  Wait until it warms up some more to prune frost damaged plants.  Even wait until next month to fertilize.  

But do prepare your soil for March summer veggie planting.  Dig if you must – I’m a no-dig, no weed person who leaves the living soil structure intact [see Gaia’s Garden, 2nd edition, chapter on soil].  Instead, prepare your soil by layering good stuff on top, called Lasagna Gardening, sheet composting, composting in place, or on-the-ground composting!  Garden smart!  If it is already there, you don’t have to move it from the compost pile to where it is needed!  Build your soil in place or in your new raised beds!  If you are putting raised beds on top of your lawn, lay down several layers of heavy cardboard first, to stop the grass and weeds, thoroughly soak it, then layer, layer, layer!  When they get there, your plant’s roots will easily poke their way through the cardboard.  Definitely attach gopher proof wire mesh to the bottom of your raised bed frame before you start filling it, unless you are creating your garden on top of concrete or a roof.  If you are container gardening, check out Patricia Lanza’s book Lasagna Gardening for Small Spaces: A Layering System for Big Results in Small Gardens and Containers: Garden in Inches, Not Acres. 

Healthy layering should be 2 dry/Carbon to 1 wet/Nitrogen. 

Carbon – carbon-rich matter (like branches, stems, dried leaves, peels, bits of wood, bark dust or sawdust, shredded brown paper bags, coffee filters, conifer needles, egg shells, hay, peat moss, wood ash) gives compost its light, fluffy body.
Nitrogen – nitrogen or protein-rich matter (manures, food scraps, leafy materials like lawn clippings and green leaves) provides raw materials for making enzymes. 

  • Lay twigs or straw first, a few inches deep. This aids drainage and helps aerate the pile.
  • ADD dry materials – straw, leaves and wood ashes. If you have wood ashes, sprinkle in thin layers, or they will clump together and be slow to break down.  Fine chopped, smaller materials decompose faster.
  • Lay on manure, green manure ( clover, buckwheat, wheatgrass ) or any nitrogen source. This activates the compost pile and speeds the process along.  Put on rinsed seaweed for minerals, scatter some yarrow sprigs to further speed decomposition, and, of course, your kitchen food waste. 
  • Think how that pile is going to decompose lower and lower.  Build enough layers to get the amount of soil you need.  Could be 18” high.
  • If you like, sprinkle some microbe rich topsoil over it all to ‘inoculate’ with living soil organisms that will immediately go to work.  Add a few handfuls of red wriggler compost worms.  Add any other amendments that make you happy.
  • Install some pathways.  Don’t walk on your oxygen rich breathing brew and squeeze the life out of it, or crush your worms and soil structure!  Keep things fluffy for good soil aeration and water absorption.   
  • If you need to, for aesthetic reasons, cover the compost with a pretty mulch that will break down slowly.  Spread it aside when you are ready to plant.  It could be down leaves; if you need your soil in that area to be slightly acidic, cover with pine needles (strawberries).
  • If things get stinky, add more carbon.
  • You want to plant NOW, or the same day you layer?  Can do!  Or your instant soil wasn’t so instant?  OK, here’s the instant remedy.  Make planting holes in your layers, put in some compost you purchased or have on hand, mycorrhizal fungi, and plant!  The rest will catch up, and the heat from the composting material underneath will warm your plants!  You WILL have a fine garden!  

If you do also need a traditional compost pile for spot needs, consider “No-turn” composting!  The biggest chore with composting is turning the pile from time to time. However, with ‘no-turn composting’, your compost can be aerated without turning.  The secret is to thoroughly mix in enough coarse material, like straw – little air tubes, when building the pile. The compost will develop as fast as if it were turned regularly, and studies show that the nitrogen level may be even higher than turned compost.  With ‘no-turn’ composting, add new materials to the top of the pile, and harvest fresh compost from the bottom of the bin.

So here are 3 ways to save garden time and your back!  1)  No digging!  2)  Compost in place, no moving it.  3) No compost turning!  Uh huh.
