While vines, especially flowering vines, give a romantic look to a garden they can be dangerous to other plants. Vines such as wisteria, trumpet vine and bittersweet can strangle trees and other plants if allowed to grow on them for too long. English ivy is another strangling vine that's invasive in many parts of the United States. Removing vines that strangle other plants is the only way to kill them completely.
Find the base of the strangling vine in your garden. The vines may have spread throughout your garden so they could be more than one plant.
Cut the strangling vine about 6 to 8 inches from the surface of the soil. Unwind the vine from the plant it's strangling. Cut the vine into pieces to remove it if you have to.
Dig the strangling vine's roots out of the ground with a trowel. Dig as much of the roots out without digging up any other plant's roots.
Mulch over the area the strangling vine grew. The mulch prevents new plants from popping up.
Dispose of the roots and the rest of the strangling vine plant in the garbage or compost heap.
