I've got yellow spots on my Mexican White Oak leaves (sometimes called Monterrey Oak). Does anyone know what causes this, and what I need to do to doctor it?

The tree seems to be growing well, and is otherwise healthy looking, but I want to make sure what I need to do with those spots, if anything.

Help!

Welcome Raider. Sounds a lot like powdery mildew. That usually calls for an anti fungal of some kind. Ask at your local county extension or even a garden center for what is best to use in your area and when to use it.
