Last summer (2020) several branches on our young Maple Blaze began to dry up. It looked almost like they were burnt by the sun. I took down two branches and was hopeful that the rest had little red buds on them. Now it looks like there are more branches that are sick as the red buds did not turn into little leaves in about 30-40% of the branches. You can see at the base of the tree that there is lichen or fungus. We are very worried because this sort of happened to a Pin Oak which was about 20 meters away. It had to be taken down. The maple is only 5 years old. How can I help it recover?
