My fruitless mulberry tree is almost 6 – 7 years old. At beginning of this summer, all the leaves are dying. What happened? Is it from the sun, not enough water?? Maybe the bug guy who sprays had something to do with it.
Well, sounds like all of the above could certainly contribute to this. Heat stress and too little water are the most common reasons for this so I would up the amount of water to give the tree some relief. you mention someone spraying. What was it? It is possible that the tree could have been affected by the over spray from whatever the guy was using. I would spray the tree down well with water in an attempt to save it.
