Answer: Based on your description I am not certain what has happened. I would strongly suggest you consult with your local county extension. They should be able to help you diagnose the problem(s) with your tree. Based on knowing that, if it is something that requires a chemical control then they will also have the most up to date information on what to use and how/when to apply it for maximum results. They would also be able to help you develop an appropriate routine care and maintenance program for the tree. I am sorry you are having trouble with your tree.
