USDA Plant Hardiness Zones

The United States Department of Agriculture has conveniently divided our country into 11 plant hardiness zones starting with zone 1 for the coldest to zone 11 for the warmest. The eleven zones are further divided into a 7 b (“a” coldest, “b” warmest).

The Gulf Coast counties between Apalachicola and New Orleans are in the zones 8a, 8b, and 9a. Those lowest temperatures you expect over several years are 10 – 15 degrees in 8a, 15-20 degrees in 8b, or 20-25 degrees in 9a.  (excerpt from in “The Gulf Coast Landscape” by Mike Robertson)

What do you do when extreme cold is headed your way?

  1. Know which plants are cold hardy. Concentrate on protecting the others.
  2. Thoroughly water the half-hard, or more tropical plants 24 hours before the freeze arrives. A well-watered plant is much more likely to survive.
  3. Bring potted plants indoors, or at least inside an unheated garage. Even having plants under an overhang offers some protection.
  4. You can cover your plants. Cover the entire plant with a cloth sheet or blanket and anchor the wrap to the ground to capture some ground heat. Plastic does not work as well.
  5. Turn off and drain your sprinkler pump if a hard freeze is predicted.

 

After the freeze:

  1. Uncover your plants (heat buildup in a cold frame can kill the plant as well)
  2.  Re-prime your sprinkler pump and turn it back on.
  3. Re-water your plants.
