Last week's entry on emergency bug sprays was a response to my own bug crisis. Although I mentioned that overcrowding was stressing my usually garden-hardy Black-Eyed Susans, what we really need to talk about is that the best way to control pests is to maintain an organic garden with plenty of native plants. By using organic methods such as composting, using natural fertilizers and minerals, protecting beneficial insects by eliminating the use of broadly-applied pesticides, reducing pavement, corralling rain run-off, changing cultural attitudes toward lawns or just planting better adapted varieties of garden plants CAN break the cycle of chemical dependence that we've all become accustomed to. I was surprised to learn that bare soil in full sunlight is 25-35 degrees warmer than nearby soil under mulch or plant cover. Can large expanses of manicured lawn be that much cooler?
Bonnie sent me a link to this National Geographic Green Guide which suggests that "plant-based pest control comes from the beneficial bugs and insect-eating animals the plants attract. These pest-eaters include some birds (bluebirds, chickadees and hummingbirds are a few), bats, lizards, ladybugs, praying mantises, dragonflies, spiders, green lacewings, hoverflies, parasitic wasps and predatory mites. They will flock to a healthy, balanced ecosystem to fight the bug battle for you. Choose a varied mix of plants, with edibles alongside flowering plants like clovers, marigolds, and members of the mustard, sunflower, celery and carrot family, whose nectar helps feed beneficial bugs and birds. Keep these plants healthy year-round if you can, so beneficial insects have supplementary food and dependable shelter as they control bugs throughout the year." The NJ Audubon Society lists a dozen "must-haves" for a backyard habitat and Organic Gardening has suggestions for a wildlife garden (however, we should definitely skip the "treat" section with our local bear problem!)
