The 10 Best Cold Frames
This wiki has been updated 11 times since it was first published in October of 2016. If you want to maximize the productivity of your garden, you can extend the growing season and protect tender plants against the harshest elements with one of these cold frames. They take up a lot less space than a full-blown greenhouse, and can be used to cover anything from tiny flower buds to a burgeoning crop of medicinal herbs. When users buy our independently chosen editorial picks, we may earn commissions to help fund the Wiki. Skip to the best cold frame on Amazon.
