Problems With Creeping Vines

Naturalizing

• Many creeping vines make suitable landscaping plants because they are pruned annually to control their growth. If these plants escape into the wild, though, they quickly overtake native vegetation. Some vines, such as bittersweet and honeysuckle, climb plants, engulfing and smothering them.

Competition

• Even in a landscaped setting, some vines grow aggressively and may crowd out other plants. American bittersweet, trumpet vine, honeysuckle and silver fleece all grow rampantly in moist, warm conditions. Remove suckers and prune these plants back each spring to keep them in check. Space them so they are at least 2 to 3 feet away from perennials and shrubs.

Damage

• Wisteria, climbing hydrangea and trumpet vine grow on woody branches and become heavy as they mature. These vines may damage lightweight structures and fences. Give them a strong support or let them scramble up a building. Vines, such as Virginia creeper and ivy attach themselves to structures through tiny suction cup like discs or aerial rootlets. These natural devices can damage wood surfaces, but are safe for stone or brick.

Toxicity

• Many vines have poisonous berries, leaves or seeds, potentially causing harm to people or livestock. The seeds of morning glory and hyacinth bean vine are toxic. Other poisonous vines include American bittersweet and English ivy. Use care when selecting plants if you have young children or pets.
