I have 3 large citrus trees (1 lime, 2 Meyer lemon) planted in my yard in Austin Texas. For the last few I've been wrapping them in old-fashioned Christmas tree lights and covering them in a frost jacket. Unfortunately, they have grown so big (8ft high and 8-10ft wide) I can't find a frost jacket that will cover it.

Is it riskier to leave the tree partially uncovered during a freeze or to cut the tree back this late in the year?

Cheers

Andrew
