Our corn grew to a ginormous 10′ height this year in our raised pallet beds. The roots of corn are very sturdy; we usually cut the stalks above the roots, and allow the roots to stay in the ground to decompose. Often they are there a year later, still holding the soil.
As it is October and, despite the 95 degree F. temperatures and hot, dry Santa Ana winds that are so typical of Fall here in Southern California, it is time to plant winter crops. Peas are the top of the list to plant. There are many types of peas. Some are valued to be eaten as pods when the peas inside haven’t matured. Some – and these are my favorite – produce juicy round peas that can be shelled and frozen for use all year. Some produce a lot of tendrils, and these along with the new leaves and shoots are eaten in salads and stir-fries, and are very attractive. There are also cowpeas, which are really beans that enjoy warmer weather, so not a candidate for winter crops. Best of all, peas and the rest of the legume family set nitrogen in the soil. They have a symbiotic relations ship with certain bacteria that must live in your soil for this to happen. The plant harvests nitrogen out of the atmosphere, and stores it in nodules on its roots. When the roots die, either from the plant being cut back or dying, the nitrogen is released into the soil in a plant-usable form. No need for chemical nitrogen fertilizers.
One of the problems I’ve had growing the tall peas is having the best supports for them, especially in raised beds. I never seem to have tall enough posts, or the posts fall over and chaos ensues. This year we decided that we’d already grown our pea supports: our corn.
We cut the corn stalks down to about 8 feet; above that the stalk was a little weak, and the stalks would be tall enough for our purposes. Then we planted vining (not bush) peas in and around the base of the corn. We had a lot of success with King Tut peas last year, which had beautiful purple pods (but green peas), so we opted for more of these in this bed.
Now the peas are growing rapidly, and we’ll be able to train them up the sturdy, straight corn stalks with the help of some twine. When the peas are done, we can either use the stalks all over again for another climber, depending upon how they last over winter, or we cut the corn and the pea plants at the surface of the soil and put the whole pile into a compost pile, or into another raised bed. Corn is a hungry plant, so the pea’s nitrogen-fixing capability will help restore fertility to that raised bed. Remember that we use no fertilizer other than in-bed composting using kitchen scraps, plant cuttings, manure from our hens, and leaves, and anything else that will decompose. The beds are being watered by salty well water, too.
To help deter mice we sprinkle red pepper flakes over the seeds, and Miranda makes up a spray bottle full of hot sauce and water and sprays the beds in the evenings.
Re-purposing is so fun, especially when the result is better soil, healthier plants, and less work for us!
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 you can click to see how it works.
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 says this Bed Bug Specialist Los Angeles California; what better excuse for sitting in your garden looking at flowers?
For that is where you’ll see most of the beneficials.
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.
Take a good squint at them and you’ll see very tiny creatures dining out on the pollen and nectar, and possibly each other.
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.
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.
There were adult ladybird beetles as well, but the number of larvae was incredible.
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.
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.
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.
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.
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.
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.
Some night creature has been enjoying our pumpkins… if I see a Jack O’Lantern face being chewed into the side of it, then I’ll be setting up the night camera!
Update: I suspected that this was the culprit! Bon appetite, Madam Rat.
This year should have been dubbed The Year of the Gopher. Every year brings an increase (and decrease) in some element in nature. There are big earwig years, painted bug years, cabbage moth years, just as there seem to be good and bad years for certain crops. This year seems to be a big one for gophers.
Pocket gophers are native to Southern California, and have their special roles to play in the landscape. They aerate, their tunnels are homes to lots of other animals and insects such as Pacific Chorus frogs, toads and lizards. They are food for snakes, raptors and even greater egrets. Their tunnels allow rainwater to penetrate the soil. And, like any of us, if offered really tasty specialty food they’ll go for it.
Gopher tunnels are prime real estate. As explained in a past post, it takes a considerable amount of energy for gophers to dig tunnels, and if you kill them, new gophers reoccupy the tunnels from surrounding property. They are territorial and so the young are always looking for opportunities to have their own tunnel system.
Methods we’ve been using to train our gophers have been challenged this year by the desperation of our gophers, caused no doubt by the changing weather and growth patterns. In our kitchen garden we’ve lost a lot of veggies this spring.
We don’t trap and kill here, so we work with animals because this is their home and habitat. Permaculture isn’t about taking over an area to the loss of everything that usually lives there, its about working with nature and learning from it. So the reason our kitchen garden has been attacked is that we didn’t prepare well enough to live with the gophers. The only way to keep plants safe is to have boundaries around root balls. Trees we plant in gopher cages, but vegetables -not so much.
So Miranda and I decided to bury 24″ tall 1/4″ wire around the garden.
These tasks always sound so easy! Trenching through clay in the heat of early summer has been a challenge. Gopher tunnels dug for food collection are within the first 18″ of dirt, and their nests are down to about 24″.
We pulled back sheet mulch on the pathways and found incredible fungal activity, loads of worms and moisture.
While trenching we found gopher tunnels into the garden, and often would find dirt in the trench under the holes as the gopher backfilled, trying to make a new dirt tunnel across the channel.
Along one active area I buried the wire, but also wanted to retard the invasion of Bermuda grass. Along with the wire I buried a couple of pieces of scrap 3/4″ plywood to make a physical boundry for the grass, and these happen to be right where a gopher tunnel was. The next morning I was in the garden and I heard a strange thumping sound, and finally realized that it was coming from underground where the wood was buried. The gopher was trying to get through the new wooden fence and wire!
We’ve buried wire around three sides (40′ long by 20 – 24″ deep), and are slaving away at the last trench where the most gopher activity is.
As we’re working, we’re also using a spade to collapse gopher tunnels from the back out, and using the smucky water (this batch is made from onion peels and bits leftover from pickling whole onions) to ruin those tunnels. We’re herding the gopher out of the garden and fertilizing at the same time.
We’ve a couple more bouts left to go before finishing; my partially numb hands are ready to be done with it. Narrow trenches in heavy clay right next to a fence aren’t easy to work in, which slows the process down a lot. Knowing that we’re being true to what we believe in, to not trap and kill in our garden, makes it all worth the work. The gopher is welcome to all the weed roots it wants elsewhere.
