All I can do with my medium sized tangerine tree is wrap the trunk to try and save the plant, if not the existing branches. It is just too large to do more. I am trying to hold a bit of today's soil warmth for the young tree. The full sized tangerine will just have to struggle through unprotected. It has lost branches before, but lived and produced again.
The tiny lemon and grapefruit each are getting a full blanket. I will be thankful if any of them survive, and I know that at the least many branches will be lost. Is it worth this risk of loss to pick tangerines in my yard at Thanksgiving? Absolutely.
