It sounds like the tree has sooty mold (the black you are seeing), which is actually an indicator of a pest infestation. I would recommend treating the tree with neem oil. This will treat both the pests and the sooty mold fungus. Here is more information that may help: https://www.gardeningknowhow.com/plant-problems/disease/how-to-get-rid-of-sooty-mold.htm
