I have 2 palms about 15 feet tall that are 7 years old. Every year they have grown like crazy, but this year we had a cold winter here in TX. where we had freezing temp. 4 days or more. And the wind beat all the old dead leaves off. They have not produced any new leaves so far and It's almost july by this time they would have already started to grow. Can someone please tell me if they might know what's going on with them. Will they come back this year or next or have we lost them ?? The trunk and the rest of the tree looks ok. Please Help
