I have poison ivy growing in and around most of my shrubs and plants. I know Round up will kill it(as far as i have been told) but i don't know how to attack it since it is growing all within my shrubs and peeking out of the tops of them.I just can't get to them w/o totally butchering the shrubs.Also, how to i get rid of it FOR GOOD!? Is there something i should do to the root areas?I have been able to pull it out at the root but it seems like there's more in the ground. Also, what can i do for next year?I just bought the house
