Coleman says you can find simple, inexpensive options out there to protect your plants. If you’re already using a cold frame, he recommends getting six unused 2x4s and building an A-frame around the structure, then wrapping the new enclosure in greenhouse plastic.
No cold frame? No problem. Coleman is also a big fan of “hoop houses,” small enclosures made from semicircle-shaped strips of metal or plastic piping covered in plastic. “I’ve been doing this a long time, and I’m still like a little kid when I go in there and see what’s happening,” he says. “It’s amazing that it just works.”
