The Science of Gardening
Posted on November 30, 2008 Comments (1)
Do go ahead and dig in soil improvements, Chalker-Scott advises, for vegetable gardens or annual flowerbeds, in which nutrients need replacing yearly. But there’s really no need to dig organic amendments—manure and peat moss, etc.—into landscapes that are permanent. Treat those plantings of trees and shrubs as if they were forest ecosystems, not agricultural fields—wood chips and decaying leaves on top, no tilling-in of fertilizer.
It must drive both authors nuts to hear people say, “I’m an organic gardener. I never use chemicals.” Everything on earth is composed of chemicals.
The last line calls to mind the recent Royal Society of Chemistry attempt to reclaim the word chemical from the advertising and marketing industries: £1,000,000 for 100% chemical free material. A good example for our scientific literacy posts.
