Maple Issues

Anonymous added on September 10, 2015 | Answered

I have number of Maple trees, each around 4 years old. Lately their leaves have become a lot smaller with white mildew spreading out from the veins. They also have a green/yellow lichen on the branches which seems to be taking over the bark. I don't think the lichen is an issue but I am concerned that with the stunted growth it will completely cover the tree. I have 2 images if that would help you identify the problem.

    Lichens and moss are generally not an issue on tree bark.
    The white mold spots you discuss are likely a fungus of some kind. The fact that you have a number of trees effected can be of concern.
    I would recommend a professional arborist inspect your trees for a proper identification and treatment coarse.
