A cold frame greenhouse is a terrific way to stretch the gardening season and to offer a sheltered setting for your plants. These compact growing structures are a welcome addition to any backyard, even if you have a conventional greenhouse. They’re an excellent spot for your greenhouse plants to adjust to the outdoor conditions prior to planting them. Plus, they’re just the thing for starting seedlings in the springtime.

A cold frame greenhouse is basically a bottomless wooden box measuring approximately a foot high which is either placed on the ground or sunk in several inches. If you would like to plant directly into the frame, then put in about four or five inches of compost and topsoil. It is possible to make it any size you prefer, just be sure you are able to get at everything within it. A cold frame depends exclusively on sunshine for its heat, therefore be sure to situate it in a secluded area that receives lots of sunshine and is shielded from strong winds.
