I've been trying to control some poison ivy around my place. Got some climbing up trees and also in planters around. I did clear out a lot, including cutting a 5" notch in the seveeral of the climbers and painted them all with round-up.

Anyone know if the round-up (full strength generic) will have an affect this time of year? Since I already have the vines cut it won't be hard to re-paint them. Just curious.
