Go to Hewitts and get a bottle of Bonide’s Stump and Vine Killer. Follow the vines back until you locate the main stem where the vine emerges for the ground. Cut the vine a few inches above where it emerges from the soil. Where you have made the cut, paint the Vine Killer (full strength..do not dilute) onto the cut and bark just below the cut. Be careful not to get it on any of the other plants nearby or it will kill them too. If there are multiple vines emerging from the soil, you’ll need to cut and paint them all with the Vine Killer. That’s it….end of vine.
