Fruitless Mulberry Tree
I have two trees that the bark is breaking off and the leaves have been falling off for several months. Do they have a disease?
The breaking bark is possibly a symptom of a serious disease. https://www.gardeningknowhow.com/ornamental/trees/tgen/peeling-bark-on-trees.htm
The only way to know for sure is to have the bark analyzed by a licensed arborist, or by the county extension service. This link will help you find one:
