How To Protect Plants from Frostbite

Overview

Frostbite ruins plants. When it settles on vegetation, it burns the leaves, blooms, fruit and other parts. With smaller plants, the frost can sometimes even kill. Most gardeners will try their best to keep the frost from settling on the plants. There are several methods that are effective in doing this. Some are used for larger plants, while others only work on the smaller ones.

Step 1

Bring potted plants indoors. These are the easiest plants to protect because they can be transported. Even if you just bring them into a garage, it will protect them from the outside elements and keep frost from settling on them.

Step 2

Cover small plants with cloth or plastic bags to keep them protected from cold winds and insulate them. The cover will keep frost from settling.

Step 3

Set up heat lamps or large lights that give off heat. Hang the lights in tall trees or set heaters at the base of both small and large plants. The added heat should be just enough to avoid the frost.

Step 4

Set up fans to keep the air circulating. Moving air will not form frost. Fans must be large to have any effect if being used around trees or large shrubs. Small plants and gardens can use small fans.

Step 5

Spray the plants with water. If you know that the air will be cold enough for ice to form, the water you spray will create an ice barrier that will insulate the plants from the burn of frost. This is used on fruit trees and shrubs and can be effective with gardens as well.
