Sugar Maple tree that appears to be dying
I have a mature sugar maple tree that was planted on the Eastern side of my house about 10 to 12 years ago. It is maybe 12 or 15 feet high. It was a beautiful, healthy tree. However, the last two, maybe three years, the leaves have been much smaller. And now, there are many dead branches at the top and leaf formation is sparse. We have put tree fertilizer around the drip line the last 2 summers with no improvement. Is there any blight or pests attacking sugar maples? With all the rain, I don't think water is the issue. I fear it is dying. HELP!!!!!!
Your sugar maple is clearly in decline. There could be some kind of root problem or interior rot. It is doubtful that an insect or disease is the fundamental problem. It is closer to your house than would be optimal. https://extension.umd.edu/learn/how-do-you-decide-when-remove-tree https://extension.umd.edu/hgic/resource-library/links#trees
