hi i want to know ,what is the disease of this Mulberry tree?thanks
Thank you for contacting Cooperative Extension.
Without seeing the tree, it is very difficult to tell what the problem is. Because it appears to be a young tree, my suspicion is that is has been wounded or damaged in some way, either by animal browsing or some other mechanical injury. I do not have information on where the tree is located, and what the weather conditions have been like. The bark is peeling off, and there is dark damage showing under the bark too. It does appear to have normal green leaves. Sometimes trees can heal over wounded or damaged areas and survive. I would recommend that you try to reduce stress on the tree and evaluate it in a few months.
