 So it's just an ongoing battle, and as it starts to regrow after you've taken it down, you can use hose and other devices to chop it out and cut it out, or you can spot spray with the 20% vinegar at that point, and it will kill the young regrowth from the ground of any of those vines that we're talking about. That's the way to get them under control. You just have to be very careful.
