"I just wanted to let you know that I was very, very impressed with the quality and vigor of the Kieffer Lime I purchased from you. It came out of the box with great leaf color and quantity and has been putting on lots of new growth. Thank you!"
Winter Cold Protection
Citrus varieties have different cold tolerances. See the Citrus Variety Chart for specifics. Have an action plan in mind and the supplies you need on hand.
When temperatures are expected to go below the tolerance shown, action must be taken promptly to protect citrus trees and other cold sensitive plants.
Container trees are the easiest. Move them to a protected location where they will not freeze such as a porch, garage, or in the house.
For trees in the ground or for container trees you do not want to move, here are some other options:
Orchardists sometimes put their sprinklers on, but this only works while the sprinklers run. If they freeze up, you have ice entombed trees that may survive but may also have a lot of broken branches. This is not our preferred alternative.
