brown stuff falling from oak tree

17 years ago

Help!!! An oak tree which is shading part of my pool deck is dropping some sort of brown spots on everything below it. It's on the leaves of the plants below it as well as all over my deck below the swimming pool. Does anyone have any idea what this is and how to fix it? Any help would be appreciated.

I believe that would be acorns. Oaks do that.

Check the undersides of leaves and branches for bugs. Aphids and scale leave a mess on everything below them. Is it sticky? When my citrus trees get scale, the lower leaves get sooty mold. I have to scrub the leaves to get it off after getting rid of the scale.

Actually no, it's not sticky. It's like little brown spots, but on the plants below the tree, I can pick off the brown spots. Does that make sense? It's like they just pop right off of the leaves. Maybe a fungus of some sort?
