    This is a church I cut, I do not have an applicators license. They asked me if I knew how to treat it so thought I'd ask the LawnSite Knowledge base.
    The trees are stressed in the summer due to no irrigation, planted next to a huge asphalt lot and the top of a ridge in rocky soil, so the ground does not retain much moisture. The East side of both trees is the blackest, they look like they were burnt. Thanks for looking.

    It may be Lichen. Hard to tell from the pics. Natural. Causes no real damage.
