We have been having loads of rain (4 inches yesterday) and this just cropped up on my San Antonio Rose leaves. I did a Google search and the best guess I have is mold. It's only on tha plant...and thoughts?

If you know...what do I do to get rid of it (my thought is to take it to the street and hose the heck out of it to get it off the leaves and then wash them with a weak dishwashing soap solution).

Hmmm....odd!
