Orange tree health

Zone New braunfels, tx 78130 | Anonymous added on January 16, 2018 | Answered

We recently had a uncommon winter freeze come through my area and I wrapped my orange tree to help protect it but I don\'t think it helped all too much cause it\'s been about a week and a half since the freeze and all the leaves on the tree have gone yellow and look like the entire tree might be dying?! They are sagging and it looks very unhappy unlike before the freeze when it looked green and alive. The tree is only almost 2 yrs old. What can I do to help my tree and is it too late??

When plants have been damaged by a freeze, it is best to avoid pruning right away even if parts of the tree look dead. Pruning can allow further damage from cold weather to happen, and even if all the leaves fall off, the tree might survive and grow back next spring. The best course of action is to wait until spring to see if the leaves grow back. Then if there are dead portions of the tree, you can prune those away.

Wrapping your tree probably helped it, so it might still survive. If more cold snaps are predicted, use the same technique to protect it. Also see these articles for more information:
