Recognizing Frost Damage by Brent McGhie

Q: What are the signs that plants have been damaged by a freeze?

ALeaves and new growth are usually affected first.  Initially they will appear wilted.  Then the wilted growth will turn brown, or will turn black and become crispy.  This means these parts of the plant have died.  The temptation is to remove this dead growth immediately, but you should not prune frost-damaged plants until the full extent of the damage is apparent in the spring.

For more information see UCANR's article Frost-damaged plants may need pruning, but wait until spring (pdf).
