Answer: Unfortunately, based on your description, I am unable to make a determination as to what has happened to your plant. These plants are usually trouble free, so this is very unusual. But without really knowing what the problem is, it is impossible to suggest what to do. I would suggest you take a sample branch or two plus possibly a photo of the affected plant and consult with your county extension and/or knowledgeable nursery staff. I'm really sorry I can't be more helpful.
