For more than 30 years, Eliot Coleman of Harborside, Maine, has successfully grown food in winter without heated greenhouses. Think outside your zone. Each winter, his gardens head south, to Georgia, without moving an inch.
How? For every layer of protection–a cold frame, for example–the growing environment shifts 500 miles. By doubling up, says Coleman, winter farmers never have to contend with frozen soil, not even when the mercury drops well below zero. “You might get a little surface freezing, but by 10 a.m. it will be unfrozen,” he says. “The minute the sun comes out, all of a sudden it’s 50 degrees in there. We’ve never had a day when we couldn’t put seeds in the greenhouse beds.” For more on winter gardening, go to: Four Season Farm
