Also asked, how do you cover plants so they don't freeze?

If you are only expecting a light freeze, you may be able to protect plants in a freeze simply by covering them with a sheet or a blanket. This acts like insulation, keeping warm air from the ground around the plant. The warmth may be enough to keep a plant from freezing during a short cold snap.

How do I protect my vegetable plants from frost?

Drape sheets, frost blankets or other materials over the plants and stakes.
