Avoid fertilizing your plants in midsummer to fall, depending on your region. New growth will be at the greatest risk for freezing in cold climates.

2
Remove any empty terra cotta containers from your garden. Freezing temperatures cause them to shatter or crack because of their porous clay. Store them upside down in a sheltered place. Wrap any terra cotta pots with burlap or bubble wrap if they must be stored outside.

Bring cuttings of perennials indoors during cold nights. Make some space in a garage or shed to keep these plants. Be sure to watch the weather reports to get the plants indoors before the first frost.

Place tropical plants and annuals next to a sunny window indoors. Take plants out during the day to get sun as long as the temperature is above freezing.

Choose an area in your yard where you can dig a hole to place plant-filled containers. The surrounding soil will provide adequate insulation for plants. Apply a heavy organic mulch like hay, shredded bark, leaves or straw around the plant.

6
Cluster containers next to a south-facing wall near your house or building. Wrap bubble wrap around each container to protect the plant's roots. Place heavy mulch on top of containers.
