Jeff Moyers, Rodale's Farm Director and chairman of the National Organic Standards Board, says emphatically no. I raised this with him in our chat about the USDA People's Garden getting certified because I'd always heard it was SO burdensome to do. But Moyers sees Amish farmers having no trouble getting certified – without lawyers or big budgets at their disposal.
So how about homeowners using the term "organic" to describe their gardens? According to Moyers, as long as you're selling less than $5,000 of produce per year, you can use the term without being certified.
