Im highly allergic to it as well. I can spot it in all its seasons, look out for the version that grows up the trunks of trees(very easy to not pay attention to it). Every part of that plant year round will give you the rash. Im getting itchy just thinking about it. Those are promising finds for the surface.I dug in February once. I got the worst case of PI ever.Â
Your can't see it so it's not there? WRONG!
