Vine- heart shaped leaves
I have a row of Yew shrubs between me and my neighbor. He is in bad condition. His back and legs are not in good shape. He fell out of a tree stand last fall. I have a heart shaped vine eating up the yews and a red oak tree. It tried to engulf my Musa Banana trees too. What will kill it? Round-up at the regular mix rate did nothing. There is a take-over on his side of this vine. The whole Yew is swallowed by this vine. I don't know how to reach the source of this vine, because the yews are hiding the vine at ground level.
