The Q&A Archives: Birch Tree Dieback

Question: My mature birch trees are suffering from die back on the tops. What may be causing this, and what can be done to save them?

Answer: There are a couple of possibilites that come to mind: Bronze birch borer, or a fungal disease. These problems usually affect trees that are in a weakened state, due to poor growing conditions or extreme weather. The only way to find out for sure is to have a professional arborist take a look at the trees and make a diagnosis. You will have to at least cut out the dying portions of the trees, and treat them with great care to restore them to health. Best of luck!
