Re: Poison Ivy - Round Up at hard frost?
I recall Roger Cook helping a homeowner with a poison ivy problem. Wearing gloves and protective clothing and gear they ripped the stuff out of the ground. I'm sure that if herbicides would have worked he'd have recommended them, which I don't think he did. If you go this route, be prepared. Use gloves that you'll throw away and have a garbage bag handy for your clothing until it can be washed. When you're done, bathein cool water so that you don't open up the pores in your skin.
I can tell you from experience that Round Up does not work on poison ivy, neither does brush killer. The main problem is that the plants noxious oils basically protect the plant from things being absorbed.
I suffer from CDO ... Its like OCD, but in alphabetical order, LIKE IT SHOULD BE!!!
