I didn't see any kind of gummy substance. I contacted the place we got them from and sent them pics. They said it looked to be from the weather. It's been very hot this Summer. They also told me to spray them with a fungiside. Thanks for your info.CharlieBear wrote:Is it putting out a kind of gummy substance near where the leaves are falling off. If so it is a non treatable fungal disease that occurs most often in young trees that have been water stressed and shows up late in the season. If that is it you will have to cut off any dead wood this winter and be sure to keep the tree evenly watered for the next 2 years.
There is another fungal disease that is plaguing peach trees on the eastern seaboard that affects the thin branches of peach trees, it also has no treatment, but judicious pruning.
