I have a question about a Weeping Cherry tree that has appears to be dying. It has been around for many years and has been through all sorts of climates (heat waves, droughts, extreme cold) and has never had a problem. It could be that it just needs water, but we have never had this problem in similar weather conditions. The leaves are turning brown and falling off. The tree looks sick and dried out. There are a couple spots of an amber color sap? I have attached some pictures. Any help is appreciated
