So I have a Shamel Ash, and several rose bushes that have all turned brown and the leaves are crunchy. The trunk on the tree still seems like there is sap running through it, but the leaves are very dead. It has been a warm summer, but things are cooling down now. We had a friend who is an arborist come out and look at a Chinese Elm tree a while ago and he said that it had root rot. But our other Chinese elm tree started dying as well but then came back to life a couple months later. All these plants are in the front yard. Does anyone know what is going on with my plants? Does anyone have a suggestion of how to fix my plants?
