Former Utne Reader senior editor Keith Goetzman on environmental issues from climate change to composting.
Peat moss takes thousands of years to form and stores massive amounts of the earth’s carbon, making it a pretty unsustainable growing medium or soil additive for gardeners. In Organic Gardening magazine, Cristina Santiestevan breaks down the numbers behind peat moss production in Canada, the source of most peat U.S. sold in the United States:
Our prescient sister publication Mother Earth News touched on this issue a couple of years ago, pointing out the environmental costs of peat production while fielding an “Ask Our Experts” question, “Do you recommend peat moss to improve soil?”
Contributing editor Barbara Pleasant tacitly endorses using small amounts of peat in indoor seed starting mixtures, but count me among the budding gardeners who’d like to find a way around using peat entirely. I’ve seen coconut fiber, vermiculite, perlite, and even non-clumping clay cat litter mentioned as peat moss substitutes, but I don’t have any personal experience in trying these. Are there any green gardeners out there who have a preferred peat alternative?
