It’s way too late to start one now, but in 2015 you may want to consider using a cold frame to extend your gardening season. This method offers gardeners a technique to protect tender plants from cold weather outside the normal growing season. Gardeners can often extend the vegetable growing season by several weeks in both spring and fall.
Cold frames really work. A News leader reader from Verona told me she usually enjoys fresh, homegrown spinach all winter long from her cold frame. While they do take a bit of management to control the growing area temperature, cold frames offer many benefits.
Think of it as a low-tech, knee-high greenhouse. You can start summer vegetable plants weeks before outdoor planting. Plants are protected from harsh weather and will grow to transplant size quickly.
