How Cold for Apple Fruit?
How much cold can apples on the tree take before they are ruined by freezing?
I've got a week of cold nights coming up and 3 trees of unripe apples. The yellow delicious are at least edible and I am wondering whether I should pick them or not.
The apples have already safely made it through several nights of high 20 degrees. Cold enough to kill all the tomatoes and squash and freeze the grape vines.
Before they go dormant, the apple trees will shrug off anything down into the low 20's, but I suspect the fruit won't be that durable.
