How to Protect Outdoor Plants From Freezing Temperatures


Protecting plants from freezing temperatures is necessary during crucial times, such as when buds have already formed, flowers are blooming in early spring or fruit is still on the trees. In times like these, freezing temperatures and frost can damage the plant or ruin crops. There are several methods of protecting your plants from harm so that you can enjoy them longer or have time to get in the harvest.

Step 1

Run extension cords out to large plants and trees. If cords cannot reach far enough, you might need to use a generator. Established plants don't typically need protection from freezing weather and are used to the climate where they are living, but if they are newly installed or are bearing fruits or blooms, you might want to protect them.

Step 2

Hang high-powered lights in the tree branches and plug them in. The lights will generate heat that will swirl around the branches and keep the cold away.

Step 3

Plug heaters in at the base of trees and large plants so that the heat can rise up through the branches. You can also use fans on all size of plants. The fans simulate wind that keeps frost from settling on leaves and blooms.

Step 4

Wrap small plants with cloth or plastic. Start at the top and wrap down to the base. Use twine to tie the plastic around the base of the plant so that it doesn't blow away.
