This vine is thought to be wild muskadine ...it runs roots under the ground to spread; it spreads rapidly and grows very rapidly. It is overtaking flower beds and grassy areas and climbing my trees. I use scotts southern weed and feed for seasons, without affect . Last year I tried getting at the main root with Round up: also have tried herbicide for vining weeds. Will try to attach picture . The vine is pulpy and soft with grape like shaped leaves.
