I admit to using Roundup when necessary but I haven’t had much luck with it killing the ivy. It does OK on the honeysuckles if I can spray them and not the blueberries. Mostly I rip the vines out by hand. I found a recipe for salt and vinegar spray that I’m going to try on the ivy. The only thing with that is that the salt will kill other stuff so you don’t want to use it around flowers, etc.
I dig..and spray...and dig and spray....Pretty much in that order! Ha!!
