Insects: Pest or Partner?

Finch Frolic Garden has been insecticide-free since it was first planted. It is a wildlife habitat as well as a food forest, and there are no chemicals at all used. Instead we rely on that habitat to create an integrated pest management system.

Western fence lizards are in and out of all of our veggie beds. We use no fertilizers other than compost, so they are safe.

The abundant frogs and lizards balance out most of the insect populations, and the birds, particularly bush tits and the other smaller gleaners, do their share.

It may seem counter-intuitive to invite in and create habitat for insects when insects do the most damage.

But like humans, bugs are bug’s own worst enemy. Bring in the native insects!

Observation plays an enormous role in successful pest management; what better excuse for sitting in your garden looking at flowers?

Mexican Bush Katydid (Scudderia mexicana) on fennel.

For that is where you’ll see most of the beneficials.

A tiny jumping spider (family Salticidae) on yarrow. Spiders eat a lot of insects. The nectar draws in the bugs, and the spider waits.

In dryland areas everything is smaller: smaller tree canopies, smaller predators, smaller prey, and smaller insects. There are over 300 species of bee native to San Diego alone. None of them produce honey -there are no native honeybees to North America – but they are very important and very overlooked pollinators. Planting native plants, which have adapted over time to provide the best possible food sources in the most attractive packages, will be optimal for a native garden. Allowing non-natives that are also attractive to good bugs go to flower, along with the natives, is good too. For instance, dill, mint, basil, fennel and carrot all produce clusters of tiny flowers.

Blooming cilantro next to peas: both are good non-native small insect food sources.

Take a good squint at them and you’ll see very tiny creatures dining out on the pollen and nectar, and possibly each other. 

This scary-looking character (Chrysoperla rufilabris) is a wonderful friend, voraciously hunting many kinds of insects in adult, larval and eggs forms.

Lacewing larva are ugly ducklings that grow into lovely — and equally predatory — fairy-like adults.

Keeping a food supply for predatory insects is important to keep them in your garden. People buy ladybugs — most of which are non-native — and release them into a garden hoping they’ll linger and take care of any insect problem that might come up. Well, those poor bugs who survive packaging are hungry and thirsty. If there aren’t drops of water to sip on or aphids to munch right away, they have to go looking for them to survive. So leaving patches of plants with small infestations of aphids or other insects is important, as hard as that may be to do.

Recently while installing more raised pallet beds in the vegetable garden I was about to pull out a batch of ragweed.

Ragweed covered in aphids.

Its a native here, but an invasive one as it travels via underground runners and by seed. This batch was covered in aphids. Miranda, with her good eyesight, luckily stopped me. She saw dozens of ladybug larvae happily munching on all of those aphids.

Ragweed chock full of hungry ladybug larvae and hatched adults. They cleaned the plant of aphids and went to work on the rest of the garden.

There were adult ladybird beetles as well, but the number of larvae was incredible.

Nom!

The ragweed stayed. Eventually it was sprinkled with white aphid carcasses sucked dry by ladybug larvae. In a couple of weeks, the aphids were gone, the plant looked absolutely clean, and the ladybugs had had successful reproduction and had flown off to work in other areas of the garden and possibly in my neighbor’s yard. You are welcome. Then I pulled out the ragweed. We have plenty of it elsewhere for future ladybug mating sites.

Inspection of native plants at a friend’s house which were besieged by scale and aphids showed two things: one, that Argentine ants were farming insect on the leaves of the plant, and needed to be controlled, and that these plants also had the local rescue squad on hand. Thanks to Miranda again, she saw many types of native predatory insects feeding on the invaders.

hoverfly, beneficial insect, integrated pest management, Pseudodoros clavatus

Hoverflies or flower flies like this Four-spotted Aphid Fly (Pseudodoros clavatus) are not only our most common generalist pollinator, but also an important predator of plant-sucking insects such as aphids and thrips.

Larvae of Pseudodoros clavatus feasting on Oleander Aphids (Aphis nerii). Oleander Aphids are commonly found on milkweed.

We didn’t want to sprinkle food grade diatomaceous earth on the leaves or do anything to kill off the good guys, so we put borax ant bait in protected containers around the base of the plants and left them alone. The ants would die off and stop farming the bad guys, and the good guys would have great meals and be healthy and hardy enough to reproduce on site. The plants would recover and the natives would win.

Cryptolaemus montrouzieri, integrated pest management, beneficial

The worst gardening policy is the ‘squish first and ask questions later’ one. Although this long-haired cutie might look like the dastardly mealybug, it’s actually the larvae of the Mealybug Destroyer beetle (Cryptolaemus montrouzieri), a naturalized predator species that saved the California citrus industry once upon a time and which continues to covertly lend a hand in orchards and gardens every day.

Plants communicate in many different ways, and one of the ways is through scents that we cannot detect. These volatile organic compounds (VOCs) are released for various reasons and detected by surrounding plants. Native plants will release an alarm VOC when being attacked by insects that other natives pick up on, and they in turn release VOCs that attract the native predatory insects that will eat the pest. Having lots of native plants integrated in your landscape benefits your non-natives by calling in the rescue squad when the bad guys show up. Non-native plants, of course, release VOCs as well, but they are speaking a different language; their chemicals may not be recognized by the other plants, or they are signalling for beneficial insects that don’t live in the area. By providing good habitat – bird boxes, sources of water for birds, lizards, frogs, toads and insects, having mulches and native bee nesting boxes around the property, allowing some plants to flower, and of course, not using insecticide, you’ll have a balanced ecosystem full of wildlife in no time.

bird, integrated pest management, orange-crowned warbler

Industrious Orange-crowned Warblers (Oreothlypis celata) can be seen poking through bushes, trees and even tall lush grass prowling for small insect prey.

Remember that even if a product is from plant sources – such as neem oil or pyrethrum, doesn’t mean that it isn’t powerful. No insecticide will kill the target species and leave all the good guys alone. Scorched earth policy is never the best way to go in nature. Sprinkling food grade diatomaceous earth just where the bad bugs are and not liberally spreading it around, or using a soap and water spray on infested leaves, can help. Just look first and see if there are signs of beneficials already there working for you. 

beneficial, integrated pest management, Bracon celer

This female braconiid wasp’s tail-like long, thin ovipositor is a weapon of population regulation. She uses it to inject her eggs into the bodies of her prey — fruit flies in this species — and her maggots eat their hosts from the inside.

Remember too that if you purchase plants that have been treated with insecticide, particularly those with systemic insecticides (which means they work internally throughout the plant), they will kill anything that takes a bit out of them. The poison goes through the pollen and nectar as well. So birds nibbling the leaves, pollinators and beneficial predatory insects having a meal, butterfly caterpillars, and the insects that eat all of the above, will all be poisoned. If that milkweed you bought to feed the Monarchs don’t have aphids on them, be suspicious. Those tags at the big box stores that say the plants have been treated with insecticide – neonicotinoids – that are safe, are excluding facts about what else they effect. Systemics stay in the plant, possibly for the life of the plant. They don’t go away. GMO seeds have had their DNA modified to accept the use of chemicals, both herbicides and insecticides. Glysophate, a derivative of Agent Orange, is now found in mother’s milk, in human and animal tissue, and in most soil. We have to stop using chemicals for the health of ourselves and our ecosystem. So buy plants and seeds from sources you can trust. Just because the big box stores offer a good return policy doesn’t validate their products. You are buying inferior plants that are toxic to beneficial insects. That bug-free milkweed plant will kill the Monarch caterpillars feeding on it. The more you demand and support chemical-free plants, the more suppliers there will be. On my Resources page under Shopping I have listed many wonderful sources for plants and seeds online, but look locally first.

A minute pirate bug (Orius tristicolor) scans the deck of this native Dove Weed (Croton setigerus) leaf for any of the mites, thrips, aphids and caterpillars it makes its vittles from. No prey, no pay, and dead bugs tell no tales about this tiny but deadly predator!

Get to know your native insects. Have a seat by the flowers and take a good look – with a magnifying glass if necessary – and be amazed at the hundreds of little workers you didn’t even know that you had.

 

Rebuilding Our Habitat Pond… Again

Here in Fallbrook, CA, in San Diego’s north county, we’ve had 3 1/2 inches of rain in the past eleven months, and that came overnight several weeks ago. Last year we had a historic 20+ inches of rain which no one was prepared for, as our average is now about eight to ten inches. This year, the plants and animals are in trouble already. The days are hot and dry, with no rain in the forecast for our three rainiest months. I’ve heard people say that they never recommend a pond in a drought, but they can’t be more wrong ecologically speaking. The animals and insects need your help to survive, and they will help your yard with integrated pest management, pollination, soil building, and so much more.

Many years ago my daughter and I tore out this big juniper in front of our dining room window and dug a pond. I received a used pond liner, flagstone and some rocks for free from a source that didn’t want them. For years I had a lined pond, and I reconfigured it and the flagstones three times over the years. I’ve built new muscles lifting and hauling large, thick pieces of flagstones. With the success of our large unlined pond (blessed with thick clay at the bottom of the property) I wanted to make this little one unlined as well. The benefits would be that I could grow water plants in-ground, and better aquatic creatures could thrive in it. The problem was that up top by the house there is a lot of decomposed granite, which is porous. So I spent many a day digging up clay from various areas on the property, pushing the buckets or wheelbarrow uphill through mulch, lugging it over and lining the pond with it. Miranda hauled clay as well. Six inches of clay still didn’t seal it. I’d been refilling the pond every few days with well water, but the level would change dramatically and the Pacific Chorus Frogs that used to come to the pond in great numbers, sing deafeningly in January and February, lay eggs and then go off to eat more bugs in the yard, weren’t coming anymore. The low pond water allowed watercress and other plants to fill it up as well. Now it is frog breeding time, and there is little habitat for them.

So a few weeks ago I purchased new pond liner. My daughter and I pulled the pond apart, fed the watercress to the hens,

dug up clay and hauled it back down the hill (used it in raised beds) (best traveled clay anywhere),reshaped and enlarged the pond giving it plenty of edges, cushioned it with newspaper, 

relined it, moved around the flagstones yet again, transplanted a water lily from the big pond below into a sunken pot, transplanted creeping red fescue and a few green lilies around the edges, and installed a circulation pump which allows water to flow through a bird bath. We were finishing the work today, on this balmy, dry, 85F February 1, when Miranda noticed frog spawn attached to floating pine needles.

Over the last week while the pond had been full, the magic had already worked! So she corralled the pine needles – fallen from a newly deceased huge beautiful pine in our driveway that died because the neighbor randomly cut its roots in the heat of summer – into the shallow end to keep the spawn safe. Miranda cut some floppy dwarf cattail stems and stuck them into the submerged water lily pot so the frogs could attach their spawn to something stationery. We’d overlapped the edges with flagstone so there were plenty of sneaky places for frogs to hide out. We also have edges of different depths, for different sized birds such as the white crown sparrow below to bathe in, and they have been enjoying these areas immensely. We should charge a dirty bird spa fee!

Within half an hour of us finishing outside, while we ate a very late lunch, we had many diverse avian visitors coming in for a drink. The sound of water carries very far and will attract birds better than food sources. Even a female phainopepla, one of our few crested birds, enjoyed the new running water source. 

Followed by a mockingbird,

this wonderful thrush 

a scrub jay 

and more. Pond visitors today were also house finches, bushtits, a pair of mourning doves, bluebirds, crows, Western bluebirds, Anna’s hummingbirds, a tanager, Lincoln sparrow, and more. 

Then when the sun was about to set, the male Pacific chorus frogs gave out a practice singing session, just to see who was in the game for after it got dark.

Pacific Chorus Frogs sounding each other out around the upper pond before dark. Its breeding season!

You can make a small pond in a cattle waterer or other metal container, or suspend a big soda bottle over a concave dish and pierce a small hole in the bottom so that it very slowly drips. Provide some shelter for the animals around your watering hole, and you’ll be helping the wildlife get through these extremely dry days. They will respond by eating your bad bugs, building soil, pollinating and so much more. Be sure to watch the action, through a window or via a wildlife camera! Its better than TV, and no commercials.

Projects for the New Year

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. 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. 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.

The Ethics of Permaculture, and Getting Through Disastrous Times

The three main ethics of permaculture, according to the late Bill Mollison who wrote the Permaculture Design Manual, are 1. Care for the Earth, 2. Care for People 3. Return of Surplus. These ethics are what keep me soundly grounded in permaculture, and what we humans need to embrace in our everyday lives especially now in the face of environmental disaster. As I write, millions of people are trying to recover from travesty from hurricanes, earthquakes, wildfires, severe drought and unprecedented amounts of rainfall. That is above the starvation and political unrest that is ongoing. What is also happening to the millions of species of animals and insects, not to even think about all the domestic animals and livestock, who are also victims of these disasters isn’t even in most people’s thoughts. We live in the Anthropocene epoch, which means that now humans and human action determine the fate of everything else on earth. We have that much power. We are children driving a double-shift semi on a busy freeway going the wrong way. 

Instead of sinking into depression and denial, every one of us can make subtle changes that will help. Understanding these permaculture ethics and putting them to work in our homes, our gardens and our workplace WILL help, and will influence others to do the same. 

When I was a very easily-influenced young person, the church our family went to began a campaign around the slogan: God first, Others Second, Me Third. I took that to heart, and being naive, it also made me into a doormat for anyone with a stronger personality than me, which was practically everyone. This slogan serves the church by demanding support, instills guilt and creates identity issues. I didn’t realize that until decades later. What would have happened in my life if I’d have known about permaculture when I was in college? If I’d heard and embraced the three life-giving ethics then? Without caring for the earth, we have nothing. Did you know that over half of the oxygen we breath is created by phytoplankton in the ocean? And that all those insecticides and herbicides that are sprayed in backyards and on crops run into the ocean and are killing the phytoplankton at enormous rates? Trees and plants provide the rest of our oxygen, and with deforestation, desertification, and out of control weather catastrophies trees are dying. People are not replanting trees at a rate that will help. So where will our oxygen come from, if our first ethic is not Care for the Earth? The church’s slogan sounds devout, but it doesn’t focus on real world issues. It makes religion the most important thing rather than keeping religion in your heart as you help in practical ways. You can belong to almost any religion and embrace permaculture ethics. They work well together.

Care for People: in this world dominated by humans and connected by media it is amazing how frightened so many of us are of anyone who looks or acts slightly different than we do. How racism is alive and well, and flourishing in and under the current US administration. How governments are torturing their people in so many countries, and this is 2017! We learn history in schools for a reason, to not let the hatred repeat itself, but we aren’t teaching it well enough to make a difference. So caring for people has to be an ethic that is enacted on a daily basis. Help those you can or at the very least, just be nice. Overreaction, intolerance and obscenities seem to be the fashion, especially for young women. It began several decades ago and it still hasn’t stopped. Women don’t have to be hateful and insulting to be recognized. Realize that people act the way they do often just because they don’t understand another way to think. Just smile at those around you and see a smile back. It may help that person not mistreat someone or something else or even themselves that day. You don’t know what others are suffering from or with, so give them the benefit of the doubt.

Caring for People also means to care for yourself. Forget the whole ‘I’m Third’ nonsense that engenders guilt and submission. You are not last. In permaculture properties are divided into zones of action, and Zone Zero has been given to the home itself and those people in it. You are Zone Zero, the most important part of the design. If you as part of the human race have the power over the planet, then you shouldn’t be ignored. Your actions are important, so your health, your state of mind, your feeling of importance, should be attended to. Not that you are royalty, just that you are important. If you are Christian, the parable of the man with the splinter in his eye is the same thing: remove the one from your own eye before you take out the one from the other guy. Take care of yourself so that you can help others better. Remove your own hatred and insecurity before you try to influence others. Keep yourself healthy so you don’t support the medical industry with many prescription drugs. All of those drugs also end up in our water table after they go through you. Treat your body to healthy food and exercise. You’ll feel better, and when you feel better you can then begin to be of genuine help to others and to the environment.

Return of Surplus: Have extra time you waste? Volunteer. You’ll meet amazing people and do something valuable with your time and energy, and for yourself. Have extra fruit and vegetables? Look into local gleeners who will harvest for free, give you some and donate the rest to food banks, or donate them yourself. Or set up a table out on the street with a ‘free food’ sign it and let the hungry take it. Is your recycle bin or trash can full? Why? What can you compost? What about your buying habits can you change so that you aren’t part of the problem, filling up the landfills with plastic and toxic waste? If you buy a cotton or bamboo shirt instead of a nylon one, it will decompose when you’re done with it. Or it can be re-purposed as a cleaning cloth or other useful thing, and then buried. Buy cotton Q-tips instead of plastic ones.  Do you have a place to plant native plants? Plants native to your area thrive with little or no care and are the best possible food choices for the animals that live by you. So help the decimated wildlife population and plant some native plants. Check the ingredients on what you buy. Do you know what any of those are? Do they include palm oil? Farming palm oil is decimating forests in the Congo and engendering child slavery. Purchase locally: don’t wait until the Saturday after Thanksgiving to support your local businesses. Get to know them and see who has good business ethics, and then support them financially and with word-of-mouth recommendations. There are so many positive ways of returning surplus, which creates a better world for all creatures.

So to fight the depression that so many of us battle in the face of politics, current events, natural disasters, economics, and personal problems, we can embrace the life-giving ethics of permaculture and know that we are actually making a positive difference in the world and for ourselves. Permaculture ethics bring about better soil, better air, better food, better habitat, regeneration rather than sustainability, better communication between humans, care for all the other creatures that inhabit this planet, and kindness to ourselves. Permaculture isn’t a religion. It’s ethics transcend race, age, sex, economics, politics and education. Guilt-free. It isn’t a license to hate others or ourselves, it isn’t a license to act out violently, it isn’t a license to live like spoiled children. Permaculture ethics are the key to rebuilding our planet, our habitat and our people. And they are so simple to follow.  So today make some small choices that will have large ripple effects. Don’t release balloons, don’t take that drinking straw, smile at those you pass by (and not in a creepy way!), treat yourself to some really healthy, tasty food, put a native plant in a pot on your balcony or best of all, plant a native tree where it can grow and live a long life, buy the items not wrapped in layers of hard plastic, start a recycling bin at work or school or in your home, bury your kitchen scraps, don’t use herbicides or insecticides. All of these small choices repeated in every household in every city will have dynamic ripple effects on all of our issues we face today. You can do it. We can do it. Don’t give up.

Mallards in May

Every year our two wild mallards linger in our chemical-free pond.  They mate, Mrs. Mallard disappears for awhile, returns with very small ducklings and… they all die within days. Why? She hasn’t been a great mama. She runs them around too much, doesn’t preen them or give them time to eat. So this year when she showed up with four ducklings I didn’t even want to take photos of them. Who knows how many she began with? But these ducklings were a little older and larger than other batches had been. And they survived. They weren’t eaten by the bullfrogs in the pond, or snatched by birds, or neglected by mama. We put out wild game bird food to help them along, but Mrs. Mallard has taught them how to dabble for vegetation (they eat mostly greens).The ducklings make a ‘weep-weep’ sound when they are asking for food. One day she repeatedly dove and came up under them, and then swam underwater to the other side of the pond and back: she was teaching them how to swim underwater! Now these babies have lost their downy feathers and are growing in their primaries. They’ll be off soon, hopefully to return. Mr. Mallard has been keeping an eye on Mrs. Mallard; he sometimes pushes the babies out of the way of the food, for which we chastise him greatly. His breeding plumage is holding so if the young fly off soon, he might try for a second mating this season. Meanwhile, Mama Mallard looks pretty smug. 

Over 97% of California’s wetlands are completely gone, and what’s left is compromised by roads, pollution and management. Those billions of animals and trillions of insects which depended upon those wetlands have mostly died off, or make do with chlorinated water from the billions of swimming pools and bird baths they can find. The wildlife you see is a tiny remnant of what should be here.

To have a pond with rain water or well water in it, cleaned by fish and plants rather than chemicals, is to have a haven for wildlife. Good water is diverse with life, just as good soil is, and instead of drinking wet chemicals animals can drink water that is imbued with nutrients. The thousands of insects, reptiles, amphibians, mammals, marsupials and birds that use our pond are healthy because the water is not chlorinated. If you can put any size of pond – even in barrels – using rainwater and cleaned by plants and fish, you’ll be doing wildlife and yourself a service.

And here’s our ducklings dabbling for greens this morning: 

Ducklings!

Mrs. and Mr. Mallard really love our pond, and have adopted us for several years.  She had tried to nest on land here, even up by our garage which is a long walk from the pond, but the eggs were always destroyed in the night. Last year she returned with four young, which all disappeared quickly.  They were probably food to bullfrogs, birds, rats or other creatures.  It was very sad.

This year Mrs. Mallard went through her usual breeding time with Mr. Mallard, then disappeared, and then reappeared without ducklings.  We figured that her brood hadn’t been successful and that was that for this year.  Mr. Mallard has been losing his mating plumage, and she hadn’t been visiting.  Miranda and I figured that she was enjoying herself elsewhere.  Today as I worked outdoors I passed by the pond and to my astonishment there was Mrs. Mallard and seven adorable ducklings!  These babes are only a few days old.  She would have had to lead them walking from wherever her nest was, and somehow navigate a chain-link fence! At first she was cautious because I was talking to her excitedly and taking photos.

She watched me carefully, but then decided I was still safe and led them ashore.

She watched me carefully, but then decided I was still safe and led them ashore.

I calmed myself down and went about my work, and on one of my trips past the pond she gave me a decided look and then quickly led her brood out of the big pond just in front of me and paraded them across to the little pond.  The babies had their first sample of duckweed.

As these ponds have no chemical treatments, are topped off with rain and well water and cleaned by the plants and fish, the water is wonderful for wildlife.  They can bathe, eat and drink without ingesting or absorbing chemicals.  Good water is as microbially diverse as good soil, and all those microscopic critters are food, protection and healthy flora for all the creatures that flock to these ponds.

Later I noticed her crouched in the bog by the big pond, with all of her young out of sight underneath her. I looked around for a predator, but saw that Mr. Mallard was on the duck island and she was uncertain of him.  I stood watching them, ready to protect her. Finally he noticed her, and all went well.  A little later they were sitting together, still with no babes in sight.

I heard him fly off, probably to join some other males for some companionship.

Mrs. Mallard led her young across the pond and right to the floating duck island that is anchored in the middle of the pond.

Miranda and I were worried that the little ducklings wouldn’t be able to get aboard the raft, but they had no trouble.

This little one is so tempted to get back in the water, but he or she resists.  Its been a tiring day.

A Mallard House

For about four years now a pair of wild mallards have called Finch Frolic Garden home.  They visit most of the year, especially in mating season as it is now.  The male guards her closely as she goes off to lay an egg a day in some secluded, secret nest.  This is Mrs. Mallard’s best time of the year.

She’ll stroll all over the property while he has to follow, and it is hilarious to watch.  They get in more walking time now than in the whole year put together.  She deserves to enjoy the attention because the rest of mating season isn’t so much fun for her.

The mating occurs in the water, with the male biting her neck and holding her head under water. Ducks have drowned during mating. A couple of years ago Mr. Mallard was losing his mating plumage and decided to allow a rather mean drake have at Mrs. Mallard.  It was a violent mating, and she tried hard to get away.

The next time the imposter flew in Miranda and I were close to the pond by a lime tree, with some bushes between us and the pond.  Suddenly we noticed Mrs. Mallard slowly walking around the bushes, her head held low.  If she could have tip-toed with webbed feet she would have.  She slowly approached us and hid behind the lime tree next to us.  We took action and chased the males away, then spoke soothingly to Mrs. Mallard in a sense of female solidarity. It was quite touching to have a wild creature so trust us as to come to us for rescue.

Once the eggs have been laid the female is entirely in charge of the eggs and the hatchlings. However, if the clutch fails, the male will keep re-mating with her and she’ll keep re-nesting.  Mrs. Mallard has attempted to lay eggs on our property in the bushes, but rats or other creatures have eaten them.  She had a nest right next to our garage one year, perhaps hoping that we could protect the eggs even though by the time we realize why we’d meet a duck on the pathway by the house every day it was too late.  The stress of the mating, the egg production and laying is taxing to a wild duck’s health.  Last year she appeared leading several ducklings to our pond.  We have no idea how far she’d lead them, or how many there were to begin with, and we knew the babies probably wouldn’t last long.  We were right; they were gone by the next day.  Predation by the invasive bullfrogs in the pond, rats, weasels, hawks or any number of animals.  So sad for the mallard family.

This year Mrs. Mallard has been disappearing daily, obviously to lay an egg a day elsewhere again.  However Miranda decided to help out for future nests.  She built a mallard nesting tube. Following instructions she found online from people who have proven this design works, she rolled the first three feet of a piece of 7’x3′ hardware cloth to form a tube.

IMG_7207Also, to prevent hawks, egrets and other opportunistic birds from perching on top and snacking on eggs or hatchlings, Miranda attached strips of pokey chicken wire along the top.

Since egrets visit the pond regularly, the top of the tube had to be inhospitable.

Slipping into the chilly February pond was a shock until our legs became acclimated (or “numb”).  We pounded a hollow pipe, then slipped another pipe into it (both found materials), and then mounted the tube on top.

After mounting the nesting tube, Miranda stuffed leaves and dry grass inside, because mallards don't carry in their own nesting materials.

Miranda then lined the inside of the tube with soft nesting materials – dried grass and leaves – because mallards don’t bring them in.  A little interior decorating for future lodgers. A sprinkler riser screwed into the PVC cradle slipped into the pipe.  This way the nesting tube can be easily removed for maintenance.  The tube is about three feet above the water surface.

Mrs. Mallard hasn’t shown any interest at this point, but she’s involved with her other nest right now.  We have high hopes for a successful nest.  Anyone want to come catch bullfrogs?

 

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.

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.

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.  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?
