We have been growing through the winter to supply winter farmers' markets that we have attended for the last 7 years. While we are definately not experts we do have a good idea of how to grow greens and other cold hardy vegetables through the winter by using high tunnels, low tunnels and a minimally heated greenhouse. It's all in the timing of the planting. Most things need to reach almost full size when we are heading into November because our light in the Northeast decreases so much that we cannot count on the plants growing much more than they have once we reach November.
These are the items that we grow through the winter using very minimal heat and sometimes no supplemental heat.
These are the following storage items we include in the share
