Now's a good time to think about growing seedlings, and a great place to grow them is in a cold frame.
Cold frames are easy to build and they help ease new plants into unpredictable spring weather.
A cold frame is a season extender that allows you to harvest from the colder months to spring. The frame keeps the soil from freezing and when it's early spring, you'll be ahead of the season with harvests of great vegetables. Take an old window and build a square frame out of plywood to fit under the window. Make sure one side faces south. Lay the window on top of the frame in the garden.
