As an organic vegetable gardener, maintaining a rich diversity of life within your garden ecosystem is viatally important. “Pest control” becomes all about the natural balance of life.
Learn which bugs are friends and which are foes. Insects have many life stages (instar stages), and some bugs look vastly different at different times in their growth cycle. Case in point is the well-known beneficial ladybug, which as a “teenager” looks like a black spiky monster you’d want to crush. Some of our favorite field guides include Charles Hogue’s Insects of the Los Angeles Basin, Rodale (Barbara Ellis) Organic Gardener’s Handbook of Natural Insect and Disease Control, Allison Starcher’s Good Bugs for your Garden, and Peter J Bryant’s Butterflies of Orange County website.
1) Hospitality. The National Wildlife Federation’s Backyard Wildlife Habitat program teaches home gardeners to provide the basics that any critter needs: Food, Water, Cover, Shelter, and a Place to Raise Young. Las Pilitas native plant nursery expands this list to include open ground, nectar sources, fruit, seeds, and annual wildflower seed.
2) Protection. Protect your ecosystem by gardening organically. Chemicals (of any sort, whether herbicide, pesticide, or “fertilizer”) are not beneficial to a rich soil life population. And rich, healthy, alive garden soil is the foundation of your organic garden.
3) Think native plants. “Our native plants, having evolved here, are ideally suited to perform such ecological services as manufacturing oxygen and filtering impurities from our water. These plants also do the best job of providing food and shelter for native wild animals. Plants are a cornerstone of biological diversity. Biodiversity is vital to humans, because our survival depends on the earth and its life forms”– California Native Plant Society.
“Most of the population of California lives in the Coastal Sage Scrub plant community” says Las Pilitas.com

4) Think diversity. The more, the merrier. Different critters need different things — some need nectar, others need seed, still others need the rich layer just beneath the mulch. Provide ’em all.
5) Think year-round. You want to provide the basic ingredients (food, water, cover, shelter, place to raise young) every month of the year. It’s easy to do in springtime when everything bursts into rollicking bloom. But think about August and September and January too.
At the Community Garden at Holy Nativity, we used the “Beneficial Insect Attractant” seed mix from Bountiful Gardens catalog to begin our functional flower borders, but have added other plants to that combination throughout the years. The Bountiful Gardens mix includes blanketflower, yarrow, cilantro, California poppies, borage, bishop’s flower, calendula, and feverfew, to name a few I can remember. We have added calendula, alyssium, cosmos, sunflowers, amaranth, shasta daisy, salvia leucantha, Calif native white sage, and Calif native tidy tips, among other things.
