Irrigation and Watering
I grew vegetables in raised beds made of old bookshelf wood for many years. Then several years ago we buried that wood along with other biodegradable material in the vegetable garden and grew in the earth This is the best method of growing vegetables. However, the ongoing drought caused plant scarcity and otherwise manageable wildlife then foraged in desperation. Gophers began an onslaught of our vegetables and being a no-kill garden (except for Argentine ants) we tried many kind methods of discouraging them. Finally this year after a dry warm winter, anticipating more animal depredation, I took a friend up on their offer of free used pallets.
We sorted through stacks of pallets and found those stamped with the same name. These pallets are untreated raw pine and of a manageable and portable size. I cut each pallet in half and then nailed and screwed them together. One raised bed needed three pallets. We then covered the bottom with hardware cloth. The areas where the raised beds were to go were leveled and in several cases, de-Bermuda grassed. The pernicious weed had infiltrated our good soil and so shovelful by shovelful we turned and picked. The stolens were unceremoniously tossed into a trashcan which will solarize in the burning hot summer to come, and will then be used in compost.
On top of the leveled ground we placed cardboard. This provided a grass and gopher barrier to the bottom of the bed. Although the cardboard will break down over time, it will in the short run discourage gopher tunneling and weeds. The new pallet bed was placed on top of the cardboard.
Here is one of the tricks of having a raised bed in a hot climate: insulate it! Anything raised above soil level in hot climates are quickly heated and dried out. Raised beds notoriously have dead zones around the edges where the heat cooks the soil, killing microbes and sucking water out of the bed. Lining the inside of the bed with thick cardboard is one way to help insulate the bed, as well as planting cascading plants on the southwest side, or bushy herbs in the ground outside of the bed, or even fastening flakes of straw around the outside. With the pallets we had room to not only line the inside of the bed, but stuff cardboard down into the gaps all around the bed. We repurposed a lot of cardboard.
To fill the bed, we began with old sticks, limbs and logs as we had them. We layered these items as they were available, making sure that earth was touching each layer, and balancing green plant material with the brown as you would in a compost situation: dried tomato vines, fresh passionvine prunings, cut back rose canes, sycamore leaves, heavy clay taken from a new asparagus bed, silt from the rain catchment basins, kitchen scraps including bags of orange rinds after juicing, poopy chicken dirt from inside the hen house, poopy newspapers from the cages in which we kept sick hens indoors (crop binding), decomposable trash such as used tissues, paper towels, cotton ear swabs, junk mail (not glossy or plastic), hair, cotton balls, old cotton T-shirts, and corn husks which many people don’t know are used for compost purposes (visit https://homewarranty.firstam.com/blog/corn-husks-not-just-tamales to get all the details). As we built the beds, we’d take our time filling them as we produced ‘waste’ materials, and threw them in. When the bed was filled (and understanding that the contents would settle) and watered in with rainwater from our 700 gallon tank, we topped it with microbially rich soil from the garden beds (making sure there weren’t any grass bits hiding in it).
I stuck pieces of old 1′ PVC pipe evenly along the sides of the pallets prior to stuffing with cardboard, so that if needed I could insert wood or bamboo pieces and either build an upright sturdy trellis for climbers, or even make arches from bed to bed on which I can grow vines.
For irrigation, I connected each bed to its own set of overhead sprinklers. Each bed has its own shut off. The pipe is resting on the opposite pallet as support, and the joint where it els across the bed are threaded pieces, so the entire length can be raised and pulled out of the way so working in the bed can be easy. The irrigation is hooked up to our well water and is on the irrigation timer for a brief shower every other day. With a lasagna garden, once saturated water will be held in the organic materials that make it up, so after initial regular watering for seed sprouting or hardening off transplants you won’t need to water as much. Roots will grow very deeply.
Because we allow some vegetables to go to seed, we had to transplant vegetables from the ground where the raised beds were placed, into the raised beds. We have a forest of beets, fennel, perpetual spinach, onions, peas, arugula and lettuce in what is still in the ground, and have transplanted selections from these into the beds along with planting seeds. Fortunately we love beet greens, which don’t taste like beets and are more mild than Swiss chard.
Into one bed we’ve planted potatoes in good soil at the bottom, and are gradually filling in with straw as the plants grow. We used leaves in the soil mix, but no woody bits or other lasagna garden materials because we didn’t want to dig potatoes out of piles of old wood, nor burn the potatoes with composting materials in the shallow soil layer.
I am not a good carpenter. I however am great at figuring out what should have been done after I’ve done something. Here are some tips on building pallet beds:
I had thought about placing them on top of flat pallets to be raised off of the ground, so even less susceptible to gophers and grass, but I fortunately nixed that idea before it was enacted. The reason is that that space would be a wonderful habitat for mice or rats, or even snakes. Much as we welcome non-venomous snakes into our garden I really don’t want to startle one with my feet as I’m leaning over a bed. Of course, they would take care of the mouse and rat problem, so maybe it would be a good thing.
I had several bags of 16p galvanized nails given to me years ago, a rescue from a construction dumpster. I mean, kitchen trash-sized bags. I can’t move them, and they sit in my large shed. I opted to use some of them for this project. It was difficult hammering them into the knotty wood of the pallets, and often the holes had to be pre-drilled. Nailed wood also can pull apart, so braces across the width of the pallet to prevent bulging would have been a fantastic idea. For the last two I resorted to screws, which are far easier to both install and remove. Perhaps the nails will have to go to Temecula Recycling. If I can lift them.
We needed to build the beds quickly, as planting season bore down on us here in San Diego even earlier than usual. Here at the beginning of April we are far behind because we haven’t planted out tomato, squash, melon or cucumber seeds yet. Whew! So the beds are not beautiful, but they are functional. You can pretty up pallet beds by attaching wood around the outside, or straw flakes, or other material, and by putting wood around the top. Especially if it is repurposed wood. If you have mouse problems, then try attaching chimney flashing or other wide strips of metal around the base of the bed so that they cannot climb up the sides.
My entire vegetable patch is surrounded by a chicken wire fence, so bunnies can look but they cannot touch. We don’t have squirrels anymore in the garden because California ground squirrels like to see all around them, and our dense food forest is much too scary for them to be comfortable. Using a mild shock wire around the beds or garden fence, using metal flashing to prevent climbing, or enclosing a small garden with wire would all be ways to prevent squirrels and rats from feasting.
We covered the surrounding ground with cardboard and topped with free wood chips, for sheet mulching. This cools the soil, prevents weeds from emerging, helps choke out the Bermuda grass, and also keeps the gopher at bay. He or she must push droppings out of the hole, and if they hit cardboard, or have a shower of bark come down on them, they will go elsewhere.
Because we used non-sterile garden soil as a topper, we’ve had some weed seeds germinate but also some pleasant surprises. We planned on planting dill but found it popping up in our polyculture planting. We had several potato bits sprout, so they needed to be moved into the potato bed. Purslane, which is a weed but also one of the most nutritious greens you can eat, loves the beds so we are harvesting it regularly for chicken feed, personal use and also for making green smoothies as liquid compost for our citrus trees. Because we don’t use chemicals of any sort in the beds, there are a number of native western fence lizards loving the heck out of the beds and helping with our integrated pest management.
Some crops such as corn and tomatoes will need to go into the soil; so far gophers haven’t eaten corn, and the tomatoes can go into gopher cages up against fences or around the property on trellises or trees. The strawberries, Jerusalem artichokes and horseradish seem safe in the ground as well.
Our raised beds are working beautifully already, and the dirt and organics inside of them will be building good soil month after month until it is gorgeous compost. Except for labor, wire and a few PVC parts, they were free to build and free to fill. They can be topped off with good compost after a season, or even given another layer of old tomato vines and dried plant scraps topped with compost for the next planting season if needed. But it shouldn’t unless the height of the soil needs building, because the soil inside the bed is improving all the time.
Give it a try, and make it more attractive, and you’ll have wonderful, safe vegetables and no green waste at all.
Two years ago friend sheet-mulched her very hard, dry dirt yard using cardboard and newspaper topped with very large chunk free wood chips. Last year into this were planted a scattering of California native plants. Most of them have thrived, even surviving a frost and many 100F + days. These have been minimally watered. This week in March, after very low seasonal rainfall, we set off to plant more natives. What we found under the mulch was amazing. That light brown dirt was now moist, worm-filled soil. Under what was left of the cardboard were beautiful fungal hyphae breaking down the under layer of bark chunks into a fine surface compost. The shovel slide through the newspaper and into the ground making for very easy digging. The soil smelled good and felt alive.
Then we wanted to enlarge the planting area past the mulched area, and it was as if we were digging on another property. The shovel barely entered the dirt, and then hit hardpan within an inch of the surface. We had to chop and scrape holes to plant in. Once we did, we heavily sheet mulched around the plants.
Both of these areas, separated by a foot, have had the same rainfall and temperatures, but the mere existence of a thick layer of sheet mulch caused moisture and coolness to be retained, caused protection from hard rain, frost, high heat and dryness, compaction and wind. Just this easy combination of waste materials – wood chips and cardboard – made an incredible change in the soil structure and water retention.
Last summer when the outside temperature was in the 90’s we dug into a pile of bark chips. On the top the wood was almost hot. Three inches down, it was cool and moist even though it hadn’t rained for months. A difference of night and day. This summer I’ll obtain a compost thermometer and take readings.
Leaving the soil bare is like going out in all weather unclothed. Your skin will burn and you’ll become dehydrated in summer; you’ll freeze and also become dehydrated in the cold. In heavy rain and hail you will try to protect yourself by becoming as small a target as possible. Although the soil isn’t cowering, it is being pounded down and de-oxygenated under the onslaught of weather. With no air in the topsoil water runs off rather than sinks in. Soil bakes and there is no microbial life in the desert of the uncovered topsoil. The soil freezes and frosts, and microbes are killed; the moisture in the soil evaporating with the coming of spring. All of this damage is preventable by the application of several layers of mulch, or sheet mulch. You wouldn’t think of being outside for a long time in harsh weather without clothing, so protect your soil the way nature intends, with a carpet of organic matter.
The cardboard had gone on top of weeds. No additives were used in planting, such as gypsum, fertilizer or compost. Watering is done on an as-needed basis with a hose. I am always thrilled and awe-struck when, over and over again, I see proof of what simple soil conservation efforts have on soil building.
California poppies seeds had been planted in the planting holes the year before, and their seeds have rooted in the bark mulch. Their roots will hold the mulch together and also help change it into soil, as poppies are colonizers helping repair disturbed soil. For the price of a packet of seeds, our friend now has the beginnings of a wildflower meadow filling out the spaces between native flowering plants.
Good soil begins the food chain, beginning from what science can so far tell from microscopic mycrobes and ending in this property at least perhaps at the nesting red tailed hawk in the nearest tree, or perhaps the largest local predator, the coyote. Meanwhile the butterflies and other native insects, and all the song birds, will be on display for our friend’s enjoyment.
The sheet mulching will continue on over the slope, and as we plant we mix in pieces of old wood, we plant in shallow depressions in the ground to capture moisture and coolness, we dig a small fishscale swale above the plant to capture flowing water, and we sheet mulch heavily. It will be fascinating to keep checking that poor dirt as it regains microbial and fungal life simply through the protection of sheet mulch.
Take on one project this year that will help improve the earth. Just one. If you can manage more, fantastic. However make sure that you are fully mindful of all aspects of your project so that is it done as well as it can be.
For instance, decide to use greywater. If you can physically and legally connect your household non-toilet water pipes to a water composting system and use it to irrigate plants, then do so. If piping is impossible, then hand-carry the dishwater, shower water, bath water and cooking water out and dump it on your plants as often as you can. Make a smoothie for yourself, then clean the blender by filling it with water, blending it, and pouring that nutrient-rich residual around your plants. Yet that is not enough. Use environmentally friendly soaps. Be aware of the plastic content and chemical treatments for fireproofing or insecticide of the clothes you are washing. Plastic is in synthetic fleece, in microdermal skin treatments, in polyester bedding. You don’t have to not use greywater if you are washing synthetic fabric, but you should be mindful of what you buying. Avoid microbeads. Avoid glitter and mosquito-proofed outerwear. Choose your purchases with open eyes, thereby reducing your usage of these toxins. Build good soil to help clean the toxins from the water.
Compost. At the very least, use blender compost. That means, take a handful of soft kitchen scraps, put them into a blender, fill with water, process, and pour the very liquidy mixture around your plants. Don’t throw away any food scraps, egg shells, leftovers, sour milk, moldy refrigerator mysteries, paper towels, tissues, paper napkins, cotton Q-tips, cotton balls, cotton dental floss, hair, or anything biodegradable. If you can’t blend it up and pour it onto the earth as fertilizer, then dig a small hole and bury it, or make a pile and compost it, or layer it in a raised bed or in a lasagna garden. What leaves your house in the form of trash should only be recyclables and undecompostable items. Your garbage disposal should be rarely used if ever. Put this raw fertilizer into the ground, not into the dump. Be mindful of what you are buying and whether it can be composted or not.
Plant trees. If you are in an area with too much rainfall, you need the trees to take up the water, hold the soil and buffer the onslaught of the weather. If you are in a dry area you need trees to shade the ground, to capture ambient moisture and rain it down, to cover the hard earth with leaves. All areas need perches for animals. All areas need the oxygen supplied by the trees converting carbon dioxide gasses. All areas need reforestation with natives that thrive in indiginous locations. Be mindful of what kind of landscape you are planting. If you choose non-native trees that offer no food for animals and harm the native flora, then you are not helping. In San Diego, if you plant eucalyptus, ficus, Washingtonia palm trees, Brazilian or California peppers (not from California, but Peru), or many of the sterile fruitless versions of ornamental trees, you are taking away from the landscape rather than adding to it. I can’t begin to count how many neighborhoods I’ve been in with old plantings of ornamental plants and trees, and the area is so sterile of animals that they are like wastelands. Only survivor crows and sparrows (and loose cats) can be seen. Instead, areas with native trees are rich in many species of birds, and the insect population is under control as well. Water use is low, pollinator habitat is high, and the neighborhood feels alive and well, especially if the cats are safely tucking inside where they belong, as mine are.
Recycle. I am constantly stunned to see recyclable bottles and cans thrown into regular waste. It is important to view more here for waste management tips. The percentage of what is recycled that actually processed is low, too. So choose glass over plastic. We bought camping utensil sets to carry with us, refuse straws, and this year I’ll work on bringing containers for leftovers when we eat out rather than take a clamshell plastic container or Styrofoam one. I already wrap banana peels, leftover pastries, apple cores, and whatever is biodegradable in a paper napkin, bring it home and compost it. If you have a plastic water bottle, soda can, glass bottle, or anything recyclable, please put it in the appropriate container. Recycling has been around since I was a schoolgirl, and I can’t believe everyone still doesn’t do it.
Switch makeup. My daughter is particularly good at finding vegan, Fair Trade and non-GMO skin care products for reasonable prices. Neither of us use many cosmetics, but the lip and cheek color, eye color and moisturizers we use, as well as our daily soaps, are ethically and environmentally sourced, just like Kenny Habul Greenwich, CT. Why rub harsh chemicals into your eyes and mouth? The choices grow every day, and the prices lower all the time. Do your homework. Be mindful of what you pick up in the store. Remember that what you put on your skin is also washed down the sink and into the water table, or into your greywater. Support the businesses who have ethical business practices. This goes for men, too. Shaving cream, after shaves, toner, scent, hair products, etc. Your skin will be healthier for the change.
Shop local. Pick one or two local businesses that you know practice sustainable, ethical and conscientious business practices, who give back to their community, and give them all of your support. Buy from them, advertise for them, befriend them, give them moral support. Rate them highly on Yelp, Google, or other rating systems. Watch out for them to be sure that they can succeed. Work for them if possible. Adopt them so that they have success.
Go animal and dairy free at least one day a week. I cannot go into the scope of the damage to the environment and the horror of the treatment of food animals here. Dare yourself to find out for yourself. Read Michael Pollen’s The Omnivore’s Dilemma. Find out what happens to cows and their calves in dairies, and the heartbreaking lowing of the cows -always kept pregnant to produce milk- as their young are hauled shrieking away to be slaughtered for veal. If you think that fish and shellfish somehow have no nerves or instincts, then think again. Lobsters who are by nature competitive being held in freshwater tanks, their claws bound, among their competition, starved, and then boiled alive. If you shrug and turn away from the suffering from others, then perhaps you should analyze your food sources more. You condone practices if you support them with your wallet. So set aside a meatless and dairy-free day once a week. If the entire U.S. did not eat meat or cheese for just one day a week, it would be the equivalent of not driving 91 billion miles – or taking 7.6 million cars off the road. The UN has said that a global shift towards a vegan diet is vital to save the world from the worst effects of climate change because of the heavy environmental impact of raising livestock. Not to mention the health benefits that come from a plant-based diet; diabetes, cancer, hypertension, high blood pressure and so much more is rooted in diet. Make a Meatless Monday, or a Vegan Wednesday, or whatever, and avoid pouring cheese sauce all over some steamed veggies and calling it a good meal. Have a curry, a Turkish Eggplant Stew, a dairy free mushroom stroganoff, spring rolls, veggie lasagna, heavenly steamed eggplant, a portobello sandwich, stir-fry, bean and avocado burritos, try some non-GMO meat substitutes like those from Gardein (particularly their fish!) (no product placement, just a recommendation), or make your own seitan. Make your own vegan butter. Let your body and the environment have a break for a day.
Help Out. Choose a local charity, or a needy neighbor, and provide what they need. Don’t just give them what you want to get rid of , or what you think they should have. Often people just need reassurance or a friend to talk to, or possible solutions, or a hand for a day. Donate what your charity needs, and if that is money then do it. Help with a fundraiser. Volunteer your time. Do something to truly help someone else out, without asking for praise or cosmic bonus points in return. Don’t be a pain; be a blessing. Volunteering and helping out make you feel worthwhile and surrounds you with like-minded people who can become your friends.
I have found many of my closest friends through volunteering. Be aware of large, nation- or world-wide charities who use most of your donations for salaries and infrastructure, and very little on what they are supposed to be supporting. Don’t let the big names fool you. Use your money to help honest charities in your area, or by just sending money to people who need it, anonymously.
Whatever you choose to do, do it mindfully. Pay attention to the details, to where products come from, to the business practices of the charities and stores you support, to how animals and people are treated in the making of the products, of what is in what you handle every day. You don’t have to, nor can you, take on the world’s problems, but you can focus on one thing and stick with it; make it part of your day-to-day until it is habit. Then move to a second choice. What you do, what you buy, what you say and how you spend your time cause ripples across the earth, and being mindful of your influence will send out help rather than harm.
Happy New Year. Be healthy. Be kind. Be happy. You matter.
If you want chickens and vegetables, and have predators and opportunists trying to eat what you grow, and perhaps have limited space, this design may be for you. I did not come up with it; I don’t know who did and I give lots of credit to that person because this makes so much sense. I’ll be converting our Fowl Fortress into one as I can.
It is the Garden Coop. You build one structure of strong wire with small gauge holes to keep rats, mice and snakes out, keep your hens on one side and garden in the other, then switch.
Start with cemented posts. Your coop can be of any dimension depending upon how many chickens and how much gardening space you will need. Take that number and multiply it by two. Instead of wood you can use metal posts with metal spacers across the top if that is more cost effective for you. Make it 7 or 8 feet tall, for comfort to walk in and also to give you more vertical growing space.
Wrap the entire structure with wire, all sides and across the top, and at least six inches into the ground all the way around. This helps prevent digging animals from getting into the coop. As we have coyotes, I also pounded 6″ pieces of rebar into the perimeter every 6 inches. If you have gopher problems, then bury wire 2.5′ into the ground around the perimeter. Hardware cloth would be best although the small chicken wire is more flexible to work with. When you overlap the wire cloth be sure to sew it closed or wrap and tuck the edges, otherwise rats and mice will slip through.
Put your hen house in the center of the coop; the house should have doors on two sides.
Divide your coop in half with wire down the middle. The wire should go around the hen house, and the hen house doors should open into each half of the garden.
Now you can keep your hens in one half and garden in the other half. When a season ends, switch them.
You’ll have all of your fruit and vegetables safe from squirrels, rats, mice and birds. You’ll have vertical space on which to grow your vines. When you switch, you’ll be gardening in insect-free, well manured soil and your hens will have excellent food sources. They will be working without being let loose, and will have an active and healthy life without becoming prey. They will take apart your old garden and fix it for the next switch.
All of your water needs are in one place. All of your composting is in one place. All of your vegetable and egg gathering is in one place. You get to harvest all of your vegetables and eggs without feeding rodents. What you don’t want, you toss to the hens. All with one structure, one initial cost. Its a chicken tractor that doesn’t move!
Because you are keeping animals out physically and controlling insects with hens, you won’t be enticed to use traps, bait, sprays, etc.
You can also grow around the outside perimeter of the coop. Just be aware of shade issues from vines (maybe a good thing?) grown over the top. Summer shade with a deciduous vine may be just right for keeping your hens and garden cooler.
Its a great idea, and maybe the one that will help you succeed in your garden.
We can help the planet re-vegetate and reverse climate change. Here are three large projects that have had success and one which is still in the making because it is so vast. Watch these and be inspired, be hopeful, and plant native trees where you live:

Jordan’s Greening the Desert:
Guess what we picked today? I’ve just finished freezing the large ones to make into tomato jam and tomato sauce later, or seasoning and setting the smaller ones out to sun dry. We’ll sell these fantastically tasty foods at our Marketplace in November.
Last year, 2016, we had no tomatoes until the Fall. I couldn’t figure out why. Our summer temperatures were over 100F for days on end, peaking at 116F several of those days. The nights never cooled off and sleeping was difficult. It turns out that the tomatoes didn’t like the heat either. If temperatures consistently stay over 85F and don’t dip below 75F at night then the flowers won’t set fruit. And here I was thinking that tomatoes loved the heat! They just love the warmth, like I do.
Tomato flowers are self-pollinating. Each has both male and female parts and it takes vibration from winged insects and gentle warm winds to pollinate. Others flick them with their fingers, or set a tuning fork on them to simulate insect vibration. If there are very hot, dry winds, pollen dries out and isn’t viable. If the humidity is so high that it is sticky out the pollen swells and sticks, unable to fall to the female part of the flower. When the temperatures lowered in the Fall, even though the day length was shorter, the tomatoes quickly put on fruit.
Here in Southern California’s inland area we don’t receive snow, so tomatoes can last outside as a perennial vine for several years. However a good way to keep tomatoes for use after summer is to prune it, hanging the vine with the tomatoes in a dry area with good air circulation. The vine will die but the tomatoes – especially sauce or paste tomatoes such as Roma – will stay in excellent condition for months.
Tomatoes enjoy a good deep watering, and then let go dry in between. The tomatoes are more flavorful that way as well. Most of the tomatoes we harvested today came from volunteers that had popped up along our fenceline and receive no water, and others receive water once or twice a week along with the trees by which they are planted.
This apricot tree has been struggling with the heat and heavy clay in which its been planted, and as it has too few leaves there isn’t anything protecting the trunk and branches from the scorching heat… except for this tomato plant. The tomatoes vine upwards away from nibbling animals and are easy to pick, and the apricot receives shade. (Remember that growing under trees that have an upward growth is great, but only grow companion plants outside of the dripline of trees that have heavy skirts such as citrus and avocado).
When tomato vines die down, cut them at the soil surface and then either bury them or cover them with compost and then plant right around them. Worms love tomato vines and roots, and the vines will return nutrients to the soil. Also, tomatoes don’t care about being planted in the same place twice, so don’t worry about crop rotation. The only issue you might have is that if you plant a different variety the following year, seeds from the previous year’s tomato might come up there as well.
If your tomatoes crack on the vine, that usually means too much water, or that you’ve dumped some fertilizer on them and the growth spurt was too quick for the expanding fruit. Don’t use chemical fertilizers. Period. For anything. If you dose the tomatoes with fertilizer you’ll have lots of vines and little fruit. Also, if the tomatoes have blossom-end rot (round black dents in the bottom of the fruit) it means there is a calcium deficiency, so to prevent this bury crushed egg shells where you’ll plant tomatoes, or pour sour milk or milk products around the tomato plants.
We have tomato hornworm in our garden,but they don’t get out of control because we have birds. They take care of most of the caterpillars in the garden. Besides, the tomato hornworm is the young of the Sphinx moth,
a large lovely moth that you may see in the night.
If the temperatures remain tolerable this summer, we here at Finch Frolic Garden can look forward to lots of tomatoes to dry, can, freeze, eat fresh, make into sauce… whatever. Tomatoes are truly the taste of summer.
In drylands there is a noticeable lack of trees. This situation is kind of a Catch-22. The hotter and drier it is, the less water there is in the ground to provide for plants that can attain height, and the more the leaves of the existing trees must adapt (become smaller) to prevent transpiration and sunburn. Yet the very lack of trees and their extensive root systems, and the shade and habitat they create, and the transpiration that allows humidity to keep the air moist for pollen to survive, is one of the causes of desertification.
So how do we stop this cycle?
First, work on a manageable area. If you have a large property, then start on the area closest to your home or where you need water the most, or where water settles. As in the Annie Lamont title, Bird by Bird, you work on a piece a little at a time.
- Put in earthworks to harvest rainwater. Simple swales or rain catchment basins, perpendicular to the water flow and on contour with your property, will harvest hundreds of gallons of water each rain. You can do them with tractors, you can do them with shovels, you can do small ones with trowels above small plants. Just do them.
- Bury organic matter: hugelkultur. Do you have old wood laying around? Palm trees that are growing and being a fire hazard? Old untreated lumber full of nails? Branches? All of this can be layered into the ground. Bury organic matter downhill from your swales. If you cannot bury, then pound sticks vertically into the ground. The important thing is that you are adding organic material back into your depleted soil. It will hold rainwater, it will activate soil microbes and fungi, it will open oxygen and nutrient channels, it will sequester carbon and make it available to the plants. Our soil is mostly just dead dirt. By layering organic material with dirt you are doing what nature does, but at an accelerated pace. If your soil is unmanageable, or you can’t dig, then layer on top of the soil. Its called, among other things, lasagne gardening. Lay out newspaper, top it with fresh grass clippings or other greens, top that with dried grass clippings, dried leaves or other ‘brown’ materials, and depending upon what you want to plant in this, you can top it with mulch or with a layer of good compost and then mulch. Then plant in it! You create soil on top of the ground.
- Mulch and sheet mulch! Protect your soil from the heat and wind, and from pounding rain. A thin layer of bark will actually heat up and accelerate the evaporation process: add several inches of mulch to the ground. Better yet, sheet mulch by laying cardboard and/or newspaper directly on top of the weeds and layering an inch or more of mulch on top. This can be free mulch from landscapers, old weeds, grass clippings, animal bedding, softwood cuttings… just cover the soil to keep it moist and protected. Thick mulching alone will help keep some humidity in the air and begin soil processes, as well as reduce evaporation by reflected heat that comes from bare earth or gravel.
- Plant native plants. They thrive in our soil. Grow trees that filter the sun and don’t like a lot of water, such as palo verde, or those that take minimal additional water such as desert willow, California redbud, valley oak, or others. Grow tall bushes such as toyon, lemonadeberry, sugarbush, quailbush, ceanothusor others. Use these wonderful plants to invite in birds,butterflies, lizards and other wildlife that will begin pollination and help activate the soil.
- Design your garden for what you want to grow besides natives. Fruit trees? Vegetables? Ornamentals? They can be arranged in your mulched area in guilds to grow cooperatively.
- Grow shade. Fast-growing trees and shrubs are invaluable for protecting – ‘nurserying in’ – less hardy plants. Acacia and cassia are both nitrogen-fixers and will grow quickly to shade your plants, can be cut for green waste in the fall and also attract pollinators. Moringa is completely edible and is also an excellent chop-and-drop tree. There are many others. You need to protect what you plant from the harsh summer sunlight, and using sacrificial trees and shrubs is the most productive way to do it.
- Protect your tree trunks from scorching by growing light vines up them, such as beans or small squash.
Once you have done this process in one area, then move on to the next, like a patchwork quilt. These areas should all be planted in accordance with a larger plan that covers your entire property, so that you plant what you want in the best possible place. However, the earthworks, hugelkultur and mulching can be done everywhere. By following these guidelines, and working one small area at a time, you’ll have success, have trees, shade, food and be helping reverse desertification, one plot at a time.
Last Saturday we hosted our first workshop of 2017, featuring Alden Hough of Sky Mountain Permaculture. Alden is a master at creating earthworks, and he spent three hours here at Finch Frolic Garden teaching a class of sixteen people how to install swales correctly. The project was a small pond that overflowed and flooded when heavy rains hit. The soil is heavy clay and therefore the small pond doesn’t percolate. It is kept filled by the well, and its overflow feeds the bog and the big pond. Right now the little pond is full of native Pacific chorus frog tadpoles, which will evolve into small frogs that will go out into the landscape and eat bugs the rest of the year. He created a urbanite (cement chunks) spillway into a twenty-foot swale. The class learned what a bunyip was and how to use the water level, and how to use a laser level. The swale will hold about 300 gallons of water that would have overflowed into another area, spread and sink the water.
The swale was measured and marked on contour. Bermuda grass was pulled from it and set into trash cans to cook in the sun and hopefully be destroyed. The swale was then dug by hand. Old wood – branches, logs, boards and old posts – were laid below the swale, and covered by the dirt. This hugelkultur will absorb seeping water, aerate and enrich the soil, and provide food and water over time for the trees downhill.More dirt was needed to cover the wood so we emptied the first rain catchment basin on the property of silt and hauled it down the hill. This was a lot of heavy work, and several of our attendees worked extremely hard with the wheelbarrows. Miranda and I have a lot of experience doing this heavy work, and we are glad that this swale project also emptied this basin.
Our wonderful workshop attendees worked very hard in the heat. The end result was a swale of beauty. By creating level swales dug on contour, you can see how right it looks. It hasn’t been dug deeper into the ground at one end to force the swale to be level. If you measure on contour your swale can be of any size, and it will collect, passify, spread and sink rainwater into the landscape. Earthworks are the best way to hold water, and are imperative to reestablishing water tables, keeping wells running, keeping trees alive and maintaining springs and streams. A little earthworks will make a huge difference.
What needs to be done now is to create a dedicated overflow from the swale into the main pond. As this area receives a lot of foot traffic, we’ll also need to haul more silt to make the raised walkway more gradual and blended with the paths around. Once the tadpoles have grown and left the pond, we can drain it and use that silt. Two projects in one.
Prior to the project Miranda carefully removed a lot of healthy creeping red fescue from the work site. After the swale and spillway were dug she replanted some of it. Native yarrow will also be planted to help hold the swale.
A huge thanks to the many people who came to learn and work on site. No matter how many movies you watch or books you read, having hands-on experience makes the education click. And an extra huge thanks to Alden Hough for his expertise and hard work. Please visit Sky Mountain Permaculture in Escondido for more classes – earth bag dome building included – coming up there.
Our next Finch Frolic Garden workshop will be in April: April 22, 2pm – 4pm: The Many Benefits of Trees: Care, Nurturing and Pruning . Roger Boddaert, the Tree Man of Fallbrook and professional landscaper who planned the original garden that would evolve into Finch Frolic Garden, will talk about trees. So many trees are dying due to the drought, and we need to replace them to help shade and cool the earth and hold onto moisture. But what to plant, where and how to care for them? Roger will take you through tree care based on fifty years of experience in landscaping. Visit https://www.southernpalmetto.com/services/ and get all the details.
Go forth and dig swales!
Happy March! Finch Frolic Garden is officially open, and the trees are bursting into leaf and bloom. Birds are twitterpating and the ten inches of rain we’ve received since October are slowly working through the soil thanks to our earthworks.
Here’s an opportunity to learn just how to create accurate swales and hugelkultur so that they work. Saturday March 11th from 1 -4 we have the privilege of having Alden Hough from Sky Mountain Permaculture hold our first monthly workshop here in the garden. Alden has years of experience with building earthworks on all scales, from guiding excavators across hillsides to hand-dug. Alden will describe how to build swales and hugelkultur beds, show off equipment, and then its hands-on in the garden. You’ll learn how to use a laser level and a bunyip, and get the feel of how to build on contour. Bring your gloves and be prepared to have some fun creating earthworks, so that you can do it properly on your own property.
The workshop fee is $20/person. Please RSVP to firstname.lastname@example.org. Wear appropriate work clothes and sun protection. Complimentary vegetarian refreshments will be available. Attendees may stroll Finch Frolic Garden as well. Don’t wait!
This week here in Fallbrook, CA, at Finch Frolic Garden we received almost three inches of rain in 18 hours. Our storm pattern is changing so that there are fewer rain events, but when it rains, it really rains. For many this was a flood. Precious rainwater is channeled away from properties and into the street. In permaculture gardens the water is harvested in the earth with simple earthworks such as swales (level-bottomed ditches) and rain catchment basins.
Visitors have often expressed their desire to see the earthworks in action, so I took my camera out into the food forest. That was when the rain gauge was at about two and three quarters, with more to come. (I wanted to photograph the garden after the storm had passed but my camera refused to turn on due to the indignity of having been wet. A couple of nights in a bag of rice did it wonders.)
Please excuse the unsteady camerawork, and my oilskin sleeve and dripping hand making cameo appearances in the film. I was using my hand to shield the lens from the rain.
