In front of my house, I have large holly bushes which have some bald spots. I don't want to harm them in any way.
Will overspray from diluted Dawn detergent harm them?

I'm not sure how Dawn specifically interacts with holly, but people mix dish soap into water (and other stuff) to spray on vegetables (to get rid of insects, powdery mildew, and such), and it doesn't seem to bother the plants terribly. I wouldn't think it would hurt your plants. It might be better to do it when the sun isn't shining, though.
