There’s a very beautiful thing about Mother Nature that happens when we don’t stuff her with too much gunk: Plants grow and animals live in harmony. Yes, it sounds like a children’s book written in the 1970s, but it’s also a notion that many an organic gardener are getting wise to these days.
Companion planting, a practice used by organic and biodynamic gardeners, is the term given when one plants certain types of plants near each other because they are mutually beneficial. In the case of growing food in a garden plot, there are a number of flowers you can plant for natural pest control. Toss out the pesticides (or wait, maybe you should contact the EPA to find out how to properly dispose of that toxic waste) and instead plant some attractive and aromatic flowers. Ah, that’s biodynamic gardening for you.
