Apples_Browns-Tacoma_20091016_LAH_4005Q: I’ve planted resistant varieties and grown healthy plants, but I’m still being bugged. How else can I keep my plants pest free without resorting to spraying pesticides?

A: Let’s say you want to grow apples in your Colorado garden. You’ve selected a variety that’s resistant to fireblight (I discussed disease-resistant varieties in May), and your tree is thriving. In fact, after several years, it’s finally beginning to bear fruit. You pick your first juice, red apple, take a big bite, and… oh no! Yup, you find half a worm. Ewwww.
