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 use bleach every year ,diluted 1:3 water, I avoid spraying plants but some over-spray must hit them and I have never seen plant damage. Although none of my hollies are near the house.
I use copper sulfate crystals, dissolved in water, then placed into my pressure washer mixture reservoir. I have it to be a longer lasting solution than bleach.
To update this post: The copper sulfate solution has kept my white aluminum siding perfectly clean for now over a year.
