Hi! I have a sugar maple tree that I planted 21 years ago. The leaves are usually big and have a bright red color in fall typically mid to late Oct. The tree has been healthy up until last year, around July when I noticed that it started to get white spots on the bark of many branches. It was hit with hail from storms in 2017 and 2019 which did pit some of the branches, but I wouldn't think this would cause the white spots. Then around Aug 2020, some leaves appeared to be drying up and by mid Sept, the tree turned red and leaves fell...this was a month earlier than in previous years. Also the leaves seemed much smaller in size. Now this year, the tree did produce many helicopter seeds in spring but it really doesn't look healthy as in past years. The white spots seem to be on more branches and the tree is not as full and leaves are much smaller. Just this week, some of the leaves have started to turn yellow and are drying before they fall. Also the smaller branches seem to be dying and breaking off. The soil is sandy-type soil and I do have sprinklers that typically run every odd day for about 25 min in this zone. I'm attaching a couple of pics. I would appreciate any help and suggestions to get the tree healthy again. Thank you for your time!
