Maple tree black spots

Asked May 20, 2017, 1:03 AM EDT

Hello, I am wondering if someone could give me some insight on my newly planted maple trees. Two are autumn blaze maples and one is an October glory maple. The leaves and new twigs have black spots forming. They looked great and healthy when I planted all three in early spring. I'll attach a few images. If you could tell me what it is, if I should be worried and what I could do to help the trees it would be much appreciated.

It is difficult to tell conclusively from the photos. Please take a sample to your local county Extension office (address below) and they can send a sample to the UK Research and Education Center diagnostic lab in Princeton for positive Identification.
