Has anyone else noticed white oaks leaves turning brown?
My house is surrounded by big white oaks. The last several days I’ve noticed a rust coloring on the leaves of every tree. Tonight the wife and I went out to to Moraine State Park for a picnic. Looking across Lake Arthur I could see the same staining on white oaks there. I’m wondering if it’s some kind of mold or mildew brought on by too much rain. Doesn’t appear to be insect related.
