Cold Frame Garden

Wintertime is upon us. Cathy Isom lets us know what a cold frame is and why they are so needed in our gardens. That’s coming up on This Land of Ours.

Cold frames are bottomless boxes, with walls made of brick, straw bales, or wood and a clear top.

The “bottom” of the cold frame is actually a garden bed. The solid walls protect what’s inside from cold wind, and they help trap heat inside the frame. The clear top is usually angled towards the equator  This will allow more sun in, providing the light plants need while preventing the frosts that often kill them, while also providing enough heat to stop the soil from freezing.

Cold frames are necessary because they extend the growing seasons in the springtime and also autumn. They will help protect our plants and seeds from the extreme weather so that plants can continue to grow to thrive and be readily be available all year long.

Not all vegetables will do well in cold frames. But there are some that will, including cabbage, kale, chard, broccoli, Brussel sprouts, onions, garlic, carrots, beets, radishes, lettuces, parsnips, turnips, collards.
