Creating Rain with Canopy

Even if we don’t receive a lot of rain in drylands, we might have fog, sprinkles and other degrees of ambient moisture. This moisture can burn off with reflected heat from hard-packed earth, from gravel and hardscape, and from buildings.  It is too irregular and thin to make the use of mist nets feasible.  However, a much better way to collect that moisture and turn it into rain is the method nature uses: trees.  The layers of a plant guild are designed to capture, soften and sink rainwater, so why not just let them do it? Many trees are dying due to heat, low water table, lack of rainfall and dry air. Replacing them with native and drought-tolerant trees is essential to help put the brakes on desertification.

Please take five minutes, follow this link and listen and have a walk with me into Finch Frolic Garden as this 5-year-old canopy collects moisture and turns it into rain:

Turtle Recall

Howdy there — it’s Miranda popping in from the Facebook page to bring you a cool update. It’s been quite a while since my last post on Vegetariat: I mostly leave all the easy-peasy blog work to Diane while I’m concentrating on the excruciatingly complex and tiring Facebook stuff. I know, I’m a saint. Hey, did you know old Shakespeare the Bard invented the name Miranda? — it’s the feminine form of the Latin gerund mirandus, meaning “worthy to be admired”; so really I’m Saint Admirable of Vultusliber. (One in there for the dead language folks, thank me in the comments — or, you know, not.)

Today I want to tell you a story about some ponds, and some turtles, and some recollections. No elephants.

Those who visit us on the Facebook page may already know of our glee last April when a pair of Southern Western Pond Turtles (Actinemys pallida) appeared in our big pond.

The Western Pond Turtle group which our Southern race (I think species status for pallida is still under study) belongs to, Actinemys marmoratais an IUCN Red List “Vulnerable” species. This listing is due mostly to late 1800s to mid-1900s overharvest for food and extensive, continuing destruction and alteration of habitat. We simply don’t have wetlands anymore. They also struggle under pressures from invasive species such as Red-eared Sliders (Trachemys scripta elegans) — which will eat small pond turtles and usurp pond turtle habitat niches — and many other trials from the cornucopia of threats we offer our native species. Actinemys pallida‘s conservation status hasn’t been updated since 1996, and probably warrants at least the more critical status of “Threatened” by now.

Soooo, we were pretty excited to see not one, but two, apparently male and female judging by size, actual pond turtles in our pond. We’ve had visits from Red-eared Sliders, certainly, and captured and relocated them to sites which already have established slider populations that aren’t going anywhere. I’m afraid we haven’t the heart to kill them, so although we’re not reducing the problem, we are working to maintain an exclusive pond turtle club in our own pond.

Red-eared Slider

Adorable but sadly very destructive invasive species here in California.

We were even more ecstatic when the pond turtles stayed. We’d catch glimpses of one or both of them all summer, until in the fall only the small one seemed to still be around, popping up on the duck raft to catch some sun in the warm afternoons. As it got colder, we saw him less often, but every now and then, we’d come round by the pond and there’d be the quiet “ploop” of a small scaly body slipping into the water.

The April pair, however, were not actually the first pond turtles we’d ever had on the property.

Back in July of 2011, our big pond was still under construction and was just a big dirt bowl with water in it, and lots of other activity was under way around it as old building materials were being moved and the garden being shaped.

As you can see, the early pond had no habitat fit for anything except a pair of loons.

As you can see, the early pond had no habitat fit for anything except a pair of loons. (June 18, 2011)

We were quite astonished, therefore, when Jacob Hatch (of Hatch Aquatics) who was managing the installation discovered a small turtle hiding in a stack of boards behind the pond. Delighted and bemused by the appearance of this usually wary and probably quite squashable reptile near our stark pond, around tractors and trucks, we examined it for injuries and to determine what species it was.

Examination

A comparison with the images and info. on the wonderful CaliforniaHerps website confirmed the stripeless turtle as a rare native Western Pond Turtle, and probably a female from the apparent concavity of her plastron (‘belly’ half of shell).

The most cursory examination, however, immediately revealed the turtle’s startling absence of a left front foot.

Mrs. Sabatini

The wound was old and well-healed, and the turtle was admirably (Miranda-ishly) sprightly and seemingly unperturbed and unhindered by her partial flipperlessness.

Of course, we instantly dubbed the gimpy, watery, gimlet-eyed fighter ‘Rafael Sabatini’ (author of such famous swashbuckling tales as The Sea Hawk and Captain Blood). When we determined it was, in fact, a she, we respectfully redubbed her ‘Mrs. Sabatini’.

The second real Mrs. Rafael Sabatini, née Christine Dixon, I imagine to have been a person of some intelligence and depth of feeling, due to the fact that she had Rafael’s tombstone inscribed with “He was born with a gift of laughter and a sense that the world was mad”, the poignant first line of his novel of the French Revolution, Scaramouche.

Gimlet-eyed

Our Mrs. Sabatini was certainly full of a sense of madness — at her unjust captivity! — so we quickly released her in the only place that seemed suitable and safe on the property: the small pond at the front of our house.

Je suis libre

And that, despite our warm feelings of companionship and our admonishments to stay safe and show her face now and then, was the last we saw of the delightful Mrs. Sabatini.

Mrs. Sabatini, last seen

Life went on, as it does. And we gained that pond turtle couple last spring, so maybe-maybe we might end up with baby turtles here down the line. A distinguishing trait of a Shakespearean comedy (rather than a history or other) is that it ends with marriage, which implies future babies: it ends in the expectation of life. And I think Mrs. Sabatini would rather like the turtle story she was involved in to be a comedy — ‘gift of laughter’ and all. I can just imagine her rusty, grudging little whistly cackle guffing out as we fade to black.

However, in January this year, we began seeing multiple turtles in the pond again, rather than simply the lone male that had lingered into the fall. We became fearful that we’d been infiltrated by sliders again, as we’d see three turtles at once sunning on the raft — a new turtle maximum, and sliders are prolific and less picky about personal space. I had trouble getting good shots to check for the clearest field marks (the rounded vs. pointed shapes of the marginal scutes over the tail) so we were feeling rather turtle-scouraged, to be frank, a little turtle-glum. It’s difficult to catch a slider, but if we had them in the pond, as we had the grim feeling we did, they couldn’t stay or we’d risk all the balanced habitat we’d built up for our native species.

"Who am I? I'll never tell! Keh-heh-heh-heh-hui!"

“Who am I? I’ll never tell! Keh-heh-heh-heh-hui! (neck in, neck in)!”

Last night I decided to start catching up on my new year photo sorting. I take a lot of photos, and they all come off the camera into my ExternalHD Limbo on my desktop, where they’re eventually sorted and distributed to their homes in various folder nestings on my external harddrives. I’d managed to grab a few shots of the January turtles, and determined to examine them as best I could for slidery traits. It was time, I felt, to know for certain.

I pulled up a photo of a chummy pair of turtles I’d taken January 17th as they enjoyed the weak sunshine on the raft.

Turtles for the new year

The resolution was good, so I was able to zoom in on their faces with fair clarity. Happily, I couldn’t see any stripes, red or yellow, on the face that would indicate a slider, and their chins looked mottled-yellow as pond turtles’ do.

Looking for more clues, I panned down from the faces along the necks and shells-fronts and —

— and there it was. Or there it wasn’t.

For on the smaller turtle, who was relaxing under the friendly claw of its chelonian compatriot, where there ought to have been a small reptilian left front leg — there was none.

Mrs. Sabatini Returns

Mrs. Sabatini… had returned.

(Scaramouche, Scaramouche, she finds it difficult to do the fan-dan-go!)

“Faith, it’s an uncertain world entirely”! We certainly didn’t expect the same small, appendagially-impaired pond turtle to suddenly reappear in our pond after five years of absence.

Well, whether she’d truly been away or was simply being a lot more sneaky about using the pond so we never saw her, we’re exceedingly chuffed to know she’s back. She’s a jewel in our healthy, chemical-free habitat crown, and we’re pretty chuffed with ourselves for creating a safe, natural pond that she and her buddies — and so many other water-dependent species — can rely on.

If you build it, they will come — and come back!

Let’s keep making habitat for the small, wild, heart-pirating creatures in our lives, eh?

Plant Guild #9: The Whole Picture

3-26-13 009When set in motion the many parts of a plant guild  will create a self-sustaining cycle of nutrition and water.  By understanding the guild template and what plants fit where, we can plug in plants that fulfill those roles and also provide for us food, building materials, fuel and medicine as well as beauty.

Plant the appropriate plants for where you are placing them, for your soil and water use, and stack them in a guild with compatible plants that you can use.  The ground will be covered by a foliar density that will keep grasses and other weeds at bay and provide excellent habitat for a full range of animals and insects.  By stacking plants in a guild you are bringing life and abundance back to your garden.

Does it still sound so complicated?  Rather than try to learn the roles of all the plants in the world, start small.  Make a list of all the plants you want to plant.  List them under food bearing, culinary/medicinal herb, craft/building material, and ornamental.  Then read up on those plants.  What size are they at maturity?  Do they need full sun, partial or full shade?  If trees, do they have an upright growth so you may plant under them (stonefruit), or do they like to have their roots covered and don’t like plants directly under them (citrus and avocado)?

Citrus doesn't like plants under its canopy, but does like plants outside its dripline.

Citrus doesn’t like plants under its canopy, but does like plants outside its dripline.

Are they annuals, perennials or biennials? What is their growth habit: sprawling, rooting where they spread, upright bushy, do they need support and can they cling or do they need to be tied to a support?

Will the plant twine on its own?

Will the plant twine on its own?

Do they require digging up to harvest?  Do they fix nitrogen in the soil?  Do they drop leaves or are they evergreen?  Are they fragrant?  When are their bloom times?  Fruiting times?  Are they cold tolerant or do they need chill hours?  How much water do they need?  What are their companion plants (there are many guides for this online, or in books on companion planting.)

Do vines or canes need to be tied to supports?

Do vines or canes need to be tied to supports?

As you are acquainting yourself with your plants, you can add to their categorization, and shift them into the parts of a plant guild.  Yes, many plants will be under more than one category… great!  Fit them into the template under only one category, because diversity in the guild is very important.

Draw your guilds with their plants identified out on paper  before you begin to purchase plants.  Decide where the best location for each is on your  property.  Tropical plants that are thirsty and don’t have cold tolerance should go in well-draining areas towards the top or middle of your property where they can be easily watered.  Plants that need or can tolerate a chill should go where the cold will settle.

Once it is on paper, then start planting.  You don’t have to plant all the guilds at once… do it as you have time and money for it.  Trees should come first.  Bury wood to nutrify the soil in your beds, and don’t forget to sheet mulch.

Remember that in permaculture, a garden is 99% design and 1% labor.  If you think buying the plants first and getting them in the ground without planning is going to save you time and money, think again.  You are gambling, and will be disappointed.

Have fun with your plant guilds, and see how miraculous these combinations of plants work.  When you go hiking, look at how undisturbed native plants grow and try to identify their components in nature’s plant guild.  Guilds are really the only way to grow without chemicals, inexpensively and in a way that builds soil and habitat.

You can find the rest of the 9-part Plant Guild series here: Plant Guilds: What are they and how do they work? The first in a series. , Plant Guild #2: Canopy , Plant Guild #3: Sub-Canopy , Plant Guild #4: Nitrogen-Fixers, Plant Guild #5: Mining Plants, Plant Guild #6: Groundcovers, Plant Guild #7: Vines,   Plant Guild #8: Insectiaries .

Plant Guild #6: Groundcover Plants

Artichokes are mining plants, but also have a low enough profile to be a groundcover plant. They make excellent chop-and-drop

Artichokes are mining plants, but also have a low enough profile to be a groundcover plant. They make excellent chop-and-drop. Flanking are lavender, scented geranium (left), and borage.

In most ecosystems that offer easy food for humans, the ground needs to be covered.  Layers of leaves, organic matter from animals (poo, fur, carcasses, meal remains, etc.) , dropped branches and twigs, fallen flowers and fruit, and whatever else gravity holds close to the earth, compost to create soil and retain water and protect the soil from erosion and compaction.  Areas that don’t have this compost layer are called deserts.  If you want to grow an assortment of food for humans, you have to start building soil. Even in desert communities where there are some food plants growing, such as edible cactus, mesquite beans, etc., there is biodiversity on a more microscopic scale than in old growth forests.  In deserts the soil needs to absorb what little rain there is and do it quickly before it evaporates, and plants have leaves adapted to have small leaf surfaces so as not to dry out, and there are few leaves to drop.  Whereas in areas where there are large forests the weather is usually wetter, tall plants and thick underbrush provide multiple layers of protection both on the plants and when they fall to layer the earth.

Nasturtium reseeds itself annually, is edible with a bite of hotness, detracts aphids from other plants, and is charming. Don't let it get away in natural areas, though.

A quick way to build soil in plant guilds is to design for plants that will cover the ground. This isn’t necessarily the same groundcover as you would use to cover embankments.  For instance, iceplant can be used in a pinch, but it really isn’t the best choice in most plant guilds unless you are in a very dry climate, and your plant guild is mostly desert-type plants: date palm, etc.  Annuals can be squash or other aggressive food-producing vines such as unstaked tomatoes.  However you don’t need to consider just ground-hugging plants; think sprawling shrubs.

Scented geraniums are a great 'placeholder plant'. These Pelargoniums (not true geraniums) come in a wide variety of fragrances. We've found bird nests in these!

When guests tour through Finch Frolic Garden, they often desire the lush foresty-feel of it for their own properties, but have no idea how to make it happen.  This is where what I call ‘placeholder plants’ come in.  Sprawling, low-cost shrubs can quickly cover a lot of ground, protect the soil, attract insects, often be edible or medicinal, be habitat for many animals, often can be pruned heavily to harvest green mulch (chop-and-drop), often can be pruned for cuttings that can be rooted for new plants to use or to sell, and are usually very attractive. When its time to plant something more useful in that area, the groundcover plant can be harvested, used for mulch, buried, or divided up.  During the years that plant has been growing it has been building soil beneath it, protecting the ground from compaction from the rain.  There is leave mulch, droppings from lizards, frogs, birds, rabbits, rodents and other creatures fertilizing the soil.  The roots of the plant have been breaking through the dirt, releasing nutrients and developing microbial populations.  Some plants sprawl 15′ or more; some are very low-water-use.  All of this from one inexpensive plant.

Squash forms an annual groundcover around the base of this euphorbia.

Depending upon your watering, there are many plants that fit the bill, and most of them are usable herbs.  Scented geraniums (Pelargonium spp.), lavender, oregano, marjoram, culinary sage, prostrate rosemary, are several choices of many plants that will sprawl out from one central taproot.  Here in Southern California, natives such as Cleveland sage, quail bush (which harvests salt from the soil), and ceanothus (California lilac, a nitrogen-fixer as well), are a few choices. Usually the less water use the plant needs, the slower the growth and the less often you can chop-and-drop it.  With a little water, scented geraniums can cover 10 – 15 feet and you can use them for green mulch often, for rooted cuttings, for attracting insects, for medicine and flavoring, for cut greenery, for distillates if you make oils, etc.

Sweet potatoes make a great ground cover. Choose varieties that produce tubers directly under the plant rather than all along the stems so that you don't have to dig up your whole guild to harvest.

Sweet potatoes make a great ground cover. Choose varieties that produce tubers directly under the plant rather than all along the stems so that you don’t have to dig up your whole guild to harvest.

Groundcover plants shouldn’t be invasive.  If you are planting in a small guild, planting something spreading like mint is going to be troublesome.  If you are planting in larger guilds, then having something spreading in some areas, such as mint, is fine.  However mint and other invasives don’t sprawl, but produce greenery above rootstock, so they are actually occupying more space than those plants that have a central taproot and can protect soil under their stems and branches.  Here at Finch Frolic Garden, we have mint growing freely by the ponds, and in several pathways.  Its job is to crowd out weeds, build soil, and provide aromatherapy. I’d much rather step on mint than on Bermuda grass, and besides being a superb tea herb, the tiny flowers feed the very small bees, wasps and flies that go unsung in gardens in favor of our non-native honeybees (there are no native honeybees in North America).

Here’s a general planting tip: position plants with fragrant leaves and flowers near your pathways for brush-by fragrance.  You should have a dose of aromatherapy simply by walking your garden path.  Mints are energizing, lavenders calming, so maybe plan your herbs with the pathways you take in the morning and evening to correspond to what boost you need at that time.

Consider groundcover plants and shrubs that will give you good soil and often so much more.

Ponds and Potatoes; A Finch Frolic New Year’s Celebration

IMG_9350Our sixty degree weather here in Fallbrook, CA , gave us the opportunity to work in our garden.  A year ago – 2014 – it snowed on New Year’s Eve.  This year the nights are frosty, the days mercifully warmer, and the rain frustratingly rare.  Our promised El Nino rains are expected to hit in force within the next couple of months.  Weather they do or not, focusing on catching every precious drop in the soil, and protecting the ground from erosion and compaction, is paramount.

Permaculture in rows. Pretty nice soil, which had been silt from the street a couple of years ago, mixed with chicken straw, topped with leaves. No chemicals!

The last day of 2015 Miranda and I spent working one of our vegetable garden beds, and reshaping our kitchen garden. When we redesigned this garden by removing (and burying) the raised beds, hugelkulturing and planting, we made a lovely Celtic design.

The unplanted kitchen garden newly designed in January, 2013.

The unplanted kitchen garden newly designed in January, 2013.

However the plants just won’t respect the design, so we’ve opted to lessen the pathways, turning the beds into keyhole designs for more planting space. I’ll blog more about that in the future. Because the pathways have been covered in cardboard and woodchips (sheet mulched), the soil below them is in very good shape, not dry and compacted.

How deep do roots grow? This clump of oxalis (sour grass) is white because it was growing without light under the pathway sheet mulch. The corms at the end of the long roots are about 8 inches below the plant. Good soil means deep roots; I've never seen this plant have anything but shallow roots.

This bed has been home to sweet potatoes and various other plants, so although I try to practice the no-dig method, where you have root vegetables you must gently probe the soil for goodies.  We left some of the roots, so sweet potatoes will again rise in this bed.

We planted in rows.  Usually I mix up seeds, but this time I wanted to demonstrate polyculture in row form.  We planted three rows of organic potatoes (purchased from Peaceful Valley Organics), with a row of shallots between them.  Between the root vegetable rows we planted a row of fava beans, and a row of sugar pod peas.  Around the edges Miranda planted rows of bull’s blood beets, Parisienne carrots, and maybe some parsnips.  This combination of plants will work together in the soil, following the template of a plant guild.  We left the struggling eggplant, which came up late in the year after the very hot summer and has so far survived the light frost.

Sticks. So important for the soil. These went in vertically around the planting bed to act both as one type of gopher deterrent (a physical barrier) and also as food and as water retention for the veggies.

On top of the bed we strew dead pond plants harvested from our small pond near our house, which will be receiving an overhaul soon (hopefully before the Pacific chorus frogs start their mating season in force).  We didn’t water the seeds in, as there is rain predicted in a few days.  The mulch on top will help protect the seeds from hungry birds.

The finished bed topped with dead pond weeds (which don't have seeds that will grow on dry land!). The sticks are to steady future bush peas.

A good way to spend the last day of the year: setting seeds for food in the spring.

The little pond, which is also a silt basin, almost completely filled by an enthusiastic clump of pickerel.

Before: The little pond, which is also a silt basin, almost completely filled by an enthusiastic clump of pickerel.  This pond is wonderful habitat for birds, frogs, dragonflies, and so many other creatures, and as a water source for raccoon, possum, coyotes, ducks, and who knows what else that visits in the night.

Then on January 1 I decided it was a good opportunity to clear out the excess pickerel that had taken over our lower small pond.  With the well off for the winter, and very light rainfall, this pond has gone dry.  A perfect opportunity for me to get in there with a shovel, especially knowing that I already had a chiropractor’s appointment set for Monday (!).

Making some headway.

Making some headway.

The mud was slick and spongy, but not unsafe, and not nearly as smelly as I had anticipated.  Pickerel is not a native to San Diego, but it is a good habitat pond plant and it has edible parts.  I wasn’t tempted, however.  Its roots are thick and form a mat several inches thick hiding rhizomes that are up to an inch in diameter.  I’d cut into the mass from several sides, pull the mass out with my gloved hands and throw the heavy thing out of the pond.  Its good to be in contact with the earth, in all its forms. I couldn’t think of a better way to use the holiday afternoon.

Thick root mass hiding large rhizomes made removal a real exercise. This is why I practice yoga and attend Zumba class with Ann Wade at the Fallbrook Community Center!

I moved at least a ton of material in four hours.  Just before sunset I decided that I was done.  About an hour before that, my body had decided that I was done, but I overrode its vote to finish.  I left some pickerel for habitat and looks, and will try to contain it by putting some sort of a physical barrier along the roots, such as urbanite.

Removal of one of the three really nasty plants around the edge was a victory. The ends of their leaves are like needles, and impossible to walk past or work around, and dangerous for little kids. This root ball was harder to dig out than the mucky pickerel, and the success even sweeter. Revenge for all the pokes!

We also might harvest some of the silty clay for use in the upper pond, although the prospect of carting heavy wet mud uphill isn’t as appealing as it might sound.  That needs to happen today or tomorrow, as the aforementioned rain is expected, and I want to fill this pond again for the frogs.

After: Finished with the digging. Still more work to do -including cleanup of the mountain of organic matter - before refilling.

One good thing about the pond going dry is that there are no more mosquito fish (gambuzia) in it.  Mosquito fish are very invasive, and love to eat frog’s eggs and tadpoles far better than they do mosquito larvae.  When the pond fills with non-chemically treated water (rain and well water), some of the microscopic aquatic creatures will repopulate the water. I’ll add some water from the big pond as well to make sure there are daphnia and other natural water friends in it, which will do a much better job at mosquito control without sacrificing our native frogs.  I can’t get all the gambuzia out of our big pond, but at least they are out of the other two.  Once dragonflies start in again, their young will gladly eat mosquito larvae.

So here on the morning of the second day of 2016, I lay in my warm bed prior to rising to start the chores of the day, stiff as an old stiff thing as my body adjusts to strenuous manual labor again, looking forward to more gardening duties to prepare Finch Frolic Garden for the reopening March 1, and for the rains.

The best part of heavy gardening duties is that I can finish off the Christmas cookies guilt-free!

Plant Guild #3: Sub-Canopy!

The many layers of a food forest. Yours doesn't have to be this rampant and wild; your plant guilds can look perfectly proportioned and decorative and still be permaculture.

The many layers of a food forest, Finch Frolic Garden.  Yours doesn’t have to be this rampant and wild; your plant guilds can look perfectly proportioned and decorative and still be permaculture.

The next part of this scintillating series of What Is A Plant Guild focuses on sub-canopy, or the understory.  Sub-canopy does many of the same things that upper canopy does, in a more intensive way.

Smaller trees are ‘nurseried’ in with the help of faster-growing canopy trees; in other words, the upper canopy helps shade and protect the sub-canopy from scorching sun, high winds, pounding hard rain and hail, etc.  However, sub-canopy trees can also be made of the slower, longer-lived canopy trees that will eventually dominate the plant guild/forest.  I’ve talked about how, if an area of forest was wiped clear and roped off, in a hundred years the beginnings of a hardwood forest will have begun.  This is due to succession plants making the soil ready for the next.  Each plant has a purpose.  This phrase is an essential mantra in permaculture because it lets you understand what the plants are doing and then you can let them do it.  So if you planted a fast-growing soft wood canopy tree, maybe even one that is a nitrogen-fixer, such as ice cream bean, or acacia, with a sub-canopy trees that include both something that is going to stay relatively small such as a semi-dwarf fruit tree, along with a slower growing, hardwood tree such as an oak which will eventually become the true canopy tree years down the line, then the original softwood tree would eventually be sacrificed and used as mulch and hugelkultur after the hardwood tree had gained enough height.  Wow, that was a long sentence.  At first that hardwood tree would be part of the sub-canopy until it grows up.  Meanwhile there are other true sub-canopy trees that stay in that height zone for their life.

What makes up a plant guild.

What makes up a plant guild.

Remember, too, that plant guilds are relative in size.  If you have a small backyard you may not have room for a tall canopy tree, especially if it is detrimental to the rest of the property.  So scale the whole guild down.  Canopy for you could be a dwarf fruit tree, and sub-canopy could be blueberry bushes.  In a vegetable setting the canopy could be corn or Jerusalem artichokes, where you either leave the dead canes up overwinter (a great idea to help the birds), or chop and drop them to protect the soil, which mimics the heavy leaf drop from a deciduous tree.  The plant guild template is the same; the dimensions change with your needs and circumstance.

So sub-canopy buffers sunlight coming in from an angle.

It receives rain from the upper canopy further slowing it down and shattering the droplets so that it doesn’t pound the earth.  The lower branches also help catch more fog, allowing it to precipitate and drip down as irrigation.  Leaves act as drip irrigation, gathering ambient moisture, condensing it, helping clean it, and dripping it down around the ‘drip line’ of the trees, just where the tree needs it.

An oak working a temp job as sub-canopy until it grows into canopy, being a support for climbing roses and nitrogen-fixing wisteria.

An oak working a temp job as sub-canopy until it grows into canopy, being a support for climbing roses and nitrogen-fixing wisteria.  This is the formal entrance to Finch Frolic Garden.

With its sheltering canopy it holds humidity closer to the ground.  In the previous post I talked about the importance of humidity in dry climates for keeping pollen hydrated and viable.

It further helps calm and cool winds, and buffers frost and snow damage.  Sub-canopy gives a wide variety of animals the conditions for habitat: food, water, shelter and a place to breed.  While the larger birds, mostly raptors, occupy the upper canopy, the mid-sized birds occupy the sub-canopy.  Depending upon where you live, a whole host of other animals live here too: monkeys, big snakes, leopards, a whole host of butterflies and other insects using the leaves as food and to form chrysalis, tree squirrels, etc.  Although many of these also can use canopy, it is the sub-canopy that provides better shelter, better materials for nesting, and most of the food supply.  And again, the more animals, the more organic materials (poop, fur, feathers, dinner remains) will fall to fertilize the soil.

Sub-canopy gives us humans a lot of food as well, for in a backyard plant guild this can be the smaller fruit trees and bushes.

Sub-canopy also provides more vertical space for vines to grow.  More vines mean more food supply that is off the ground.  A famous example of companion planting is the ‘three sisters’ Native American method… what tribe and where I’m not sure of… where corn is planted with climbing beans and vining squash.  The corn, as mentioned before, is the canopy, the beans use the corn as vertical space while also fixing nitrogen in the soil (we’ll discuss nitrogen fixers in another post), and the squash is a groundcover (also will be covered in another post).  There is more to the three sisters than you think.  Raccoons can take down a corn crop in a night; however, they don’t like to walk where they can’t see the ground, i.e. heavy vines, so the squash acts as a raccoon deterrent.  To stray even further off-topic, there is also a fourth sister which isn’t talked about much, and that is a plant that will attract insects.

Back to sub-canopy, while some of it can be long term food production trees or plants, it too can also have shorter chop-and-drop trees.  Chop-and-drop is a rather violent term given to the process of growing your own fertilizer.  Most of these trees and plants are also nitrogen fixers.  These fast-growing plants are regularly cut, and here is where the difference between pruning and chopping comes to bear, because you aren’t shaping and coddling these trees with pruning, you are quickly harvesting their soft branches and leaves to drop on the ground around your plant guild as mulch and long term fertilizer.  If these trees are also nitrogen fixers, then when you severely prune them the nitrogen nodules on the roots will be released in the soil as those roots die; the tree will adjust the extent of its roots to the size of its canopy because with less canopy it cannot provide enough nutrients for that many roots, and it doesn’t need that many roots to provide food for a smaller canopy.  Wow, another huge sentence.  In this system you are growing your own fertilizer, which is quickly harvested maybe only a couple of times a year.  Chemical-free.  So, by planting sub-canopy that is long term food producing trees such as apricots or apples, along with smaller trees and shrubs that are also sub-canopy but are sacrificial to be used as fertilizer such as senna or acacia or whatever grows well in your region, you have the most active and productive part of your plant guild.

Sub-canopy, therefore, provides shelter for hardwoods, provides a lot of food for humans as well as habitat for so many animals, it provides fertilizer both because of its natural leaf drop and because of those same animals living in it, but also as materials for chopping and dropping, it buffers sun, wind and rain, holds humidity, offers vertical space for food producing vines which will then be in reach for easier harvesting, and much more that I haven’t even observed yet but maybe you already have.

The next part of the series will focus on nitrogen-fixers!  Stay tuned. You can find the entire 9-part Plant Guild series here: Plant Guilds: What are they and how do they work?

Plant Guilds #2: Upper Canopy

An oak is home to over 300 species.

An oak is home to over 300 species.  Not counting human.

Whether you are planting small plants in pots, ornamentals in your yard or a food forest, you need plants that will provide an upper canopy for others.  If you have small plants, then you will have a short canopy.  Maybe your canopy is a tomato plant.  Maybe its an oak.  Whatever it is, canopy has many functions.IMG_7446

Upper canopy provides shade so that other plants can grow.  It drops leaves, bark, flowers and seeds and/or fruit to provide compost and food for all levels of animals down to soil microbes.  Canopy provides protective shelter for many kinds of mammals, birds, reptiles and insects as they hide under the leaves. A mature oak is home to over 300 species. Old scarred canopy full of holes is the natural home for honeybees, and many types of bird and other animal.  It is a storage unit for acorns gathered by woodpeckers. Where you have animals, you have droppings. All the poo, feathers, regurgitated pellets, fur, scales and other organic waste that falls from canopy is vitally important for the health of the soil below.

Canopy provides a perch for raptors and larger birds that help with rodent control.

Canopy helps slow the wind; the fewer trees we have the harder the winds.  Canopy also filters the wind, blocking dust and other debris. Canopy helps cool and moisturize the wind. The leaves of canopy trees help buffer the rain.  Rain on bare ground is as compacting as driving over the dirt with a tractor.  If rain hits leaves it bounces, rolls or shatters.  Rain can then hit other layers below the canopy, finally rolling through leaf mulch to percolate into the soil without compacting it.

Canopy catches moisture as well.  Here in Southern California we may not receive a lot of rain, but we do have moisture during the night. Soy, fog 1-29-13 032 Often I’ve walked through Finch Frolic Garden of a morning to feed the hens, and the garden sounded as if it had its own special rain cloud over it.  That is because moisture condenses on the leaves and rolls off.  The more canopy and the higher the canopy, the more water we can collect.  In that same way, canopy begins to hold humidity on the property, which the rest of the guild contributes to.  Pollen dries out.  With longer, hotter, drier summers there is worse pollination even if the pollinators are active, because the pollen isn’t viable.  Less humidity equals fewer fruits, nuts and vegetables.  Therefore, the more canopy, and other parts of a guild, the moister the air and the better the harvest.IMG_2390

Canopy is in connection with all other plants in its community, linked via webs called mycorrhizal fungi. Through these webs the canopy sends chemical messages and nutrients to other plants.  Every plant in the community benefits from the strong communications from the canopy trees.

Canopy builds soil.  Canopy trees are large on top and equally large underground.  Tree root growth can mirror the height and width of the above-ground part, and it can be larger.  Therefore canopy trees and plants break through hard soil with their roots, opening oxygen, nutrient and moisture pathways that allow the roots of other plants passage, as well as for worms and other decomposers. As the roots die they become organic material deep in the soil – effortless hugelkultur; canopy is composting above and below the ground.  Plants produce exudates through their roots – sugars, proteins and carbohydrates that attract and feed microbes.  Plants change their exudates to attract and repel specific microbes, which make available different nutrients for the plant to take up.  A soil sample taken in the same spot within a month’s time may be different due to the plant manipulating the microbes with exudates.  Not only are these sticky substances organic materials that improve the soil, but they also help to bind loose soil together, repairing sandy soils or those of decomposed granite.  The taller the canopy, the deeper and more extensive are the roots working to build break open or pull together dirt, add nutrients, feed and manage microbes, open oxygen and water channels, provide access for worms and other creatures that love to live near roots.

Canopy roots have different needs and therefore behave differently depending upon the species.   Riparian plants search for water.  If you have a standing water issue on your property, plant thirsty plants such as willow, fig, sycamore, elderberry or cottonwood. In nature, riparian trees help hold the rain in place, storing it in their massive trunks, blocking the current to slow flooding and erosion, spreading the water out across fields to slowly percolate into the ground, and turning the water into humidity through transpiration. The roots of thirsty plants are often invasive, so be sure they aren’t near structures, water lines, wells, septic systems or hardscape. Some canopy trees can’t survive with a lot of water, so the roots of those species won’t be destructive;  they will flourish in dry and/or well-draining areas building soil and allowing water to collect underground.

In large agricultural tracts such as the Midwest and California’s Central Valley, the land is dropping dramatically as the aquifers are pumped dry.  Right now in California the drop is about 2 inches a month.  If the soil is sandy, it will again be able to hold rainwater, but without organic materials in the soil to keep it there the water will quickly flow away. If the soil is clay, those spaces that collapse are gone and no longer will act as aquifers… unless canopy trees are grown and allowed to age. Their root systems will again open up the ground and allow the soil to be receptive to water storage. Again, roots produce exudates, and roots swell up and die underground leaving wonderful food for beneficial fungi, microbes, worms and all those soil builders. The solution is the same for both clay and sandy soils – any soil, for that matter.  Organic material needs to be established deep underground, and how best to do that than by growing trees?

In permaculture design, the largest canopy is often found in Zone 5, which is the native strip.  In Zone 5 you can study what canopy provides, and use that information in the design of your garden.

IMG_7474How do you achieve canopy in your garden?  If your canopy is something that grows slowly, then you will need to nursery it in with a fast-growing, shorter-lived tree that can be cut and used as mulch when the desired canopy tree becomes well established.  Some trees need to be sacrificial to insure the success of your target trees.  For instance, we have a flame tree that was part of the original plantings of the garden.  It is being shaded out by other trees and plants, and all things considered it doesn’t do enough for the garden to be occupying that space (everything in your garden should have at least three purposes).  However a loquat seeded itself behind the flame tree, and the flame tree helped nursery it in.  We love loquats, so the flame tree may come down and become buried mulch (hugelkultur), allowing that sunlight and nutrient load to become available for the loquat which is showing signs of stress due to lack of light.  With our hotter, drier, longer summers, many fruit trees need canopy and nurse trees to help filter that intense heat and scorching sunlight. Plan your garden with canopy as the mainstay of your guild.

Therefore a canopy plant isn’t in stasis.  It is working above and below ground constantly repairing and improving.  By planting canopy – especially canopy that is native to your area – you are installing a worker that is improving the earth, the air, the water, the diversity of wildlife and the success of your harvest.

What makes up a plant guild.

What makes up a plant guild.

Canopy is improving the water storage of the soil and increasing potential for aquifers. The more site-appropriate, native canopy we can provide in Zone 5, and the more useful a canopy tree as the center of a food guild, the better off everything is.    All canopy asks for in payment is mulch to get it started.

Next week we’ll explore sub-canopy!  Stay tuned! You can find the entire 9-part Plant Guild series here: Plant Guilds: What are they and how do they work?
