I know you don't want to burn poison ivy because it is very toxic. Is it best to spray it in the spring and then in the summer try to rip it out of the ground? I swear I get a rash from just being around it when the wind blows. I need a white chemical suit and some dynamite. Dave said it and alot of people tell me, you will never kill it. That sounds like a challenge to me and I want get rid of it.
