DIY Cold Frame Plans
By Betsy Matheson Symanietz
Take on this relatively simple DIY cold frame project over the weekend to save money, extend your growing season and become a more self-sufficient gardener.
A cold frame is a simple way to create an area with a stable temperature for giving seedlings a head start in spring and for holding on to the last cold-hardy greens in the fall. You can easily construct your own cold frame, using the plans and instructions found in Weekend DIY Project: How to Build a Cold Frame, and the diagram and charts below.
