What’s Hot Now?
How can I protect my citrus trees from frost damage?
Citrus trees benefit from being planted in a sheltered area. Healthy, well-irrigated trees are better able to endure freezing temperatures. Keep the ground around citrus trees bare because bare, moist soil is better able to absorb and reradiate heat than soil covered by mulch or other ground covers. Young trees (one to three years old) can also be covered entirely, using a light material to trap heat being radiated by the ground. A frame or stakes should be used to minimize contact between the cover and leaves because ice may form where the cover touches any leaves. Sheets, burlap, or tarps are a better choice of cover material than plastic because plastic transfers more heat and if leaves come in contact with it they are more likely to freeze. The cover should extend as close to the ground as possible and be removed the next morning after the temperature rises.
