Four-season food growing in the northeastern US? It's a topic that pops into gardening and farming headlines more and more. The topic has long been of interest to me; I've practiced season extension and cold-cellaring for years. But full production in winter is a skill unto itself.
See my "Green and Growing" article in The Day/Zip06 for a profile of winter farmer Wayne Hansen. Hansen was the first certified organic grower in eastern Connecticut in 1989 and CT NOFA's Farmer of the Year in 2009. If you have trouble with the link, download the article below.
