We all want to get the most out of the growing season...
One of the most crucial ways we can squeeze one more harvest out of our veggies, is by using a cold frame.
Now I know what you are saying. "IT IS JULY!!!" But the most important thing about using cold frames, is being prepared. So we are encouraging all to start building them now, so you can get a few more kale harvests come October/November. So let us talk about cold frames.
A cold frame is a transparent-roofed enclosure, built low to the ground, used to protect plants from adverse weather, primarily excessive cold or wet. The transparent top admits sunlight and prevents heat escape via convection that would otherwise occur, particularly at night. Essentially, a cold frame functions as a miniature greenhouse to extend the growing season.
How To:
Cold frame construction is a common home or farm building project, although kits and commercial systems are available. A traditional plan makes use of old glass windows: a wooden frame is built, about one to two feet tall, and the window placed on top. The roof is often sloped towards the winter sun to capture more light, and to improve runoff of water, and hinged for easy access. Clear plastic, rigid or sheeting, can be used in place of glass. An electric heating cable, available for this purpose, can be placed in the soil to provide additional heat.
Cold Frames can be made out of any type of material for the frame, and whatever transparent material you can come across for the lid. We like to use old windows. And it is a great way to Up-Cycle old worn out materials. Your frames need not be all alike, though having two of the same size makes it possible to stack them for added height. I like frames I can move around by myself without straining, so size and weight are important considerations.
