I do minimal yard work, so excuse by botanic ignorance. In fact, regardless of what the response is, most of these plants are headed for the big garden in the sky anyway, but I'm scratching my head trying to figure out which ones are responsible for my rash. These are three likely (IMO) supects, different plants growing in the affected area, hopefully one of them is the "winner", otherwise I'll submit some more. This is picture 2. How to submit more than one picture at a time?
