Ivy is well-suited to training around a trellis or frame because of its natural vining habits. Frames include topiaries, which encourage the plants to form a shape, as well as flat wall trellises and arches. While ivy readily climbs these structures, it may not achieve full coverage on its own. Tying the ivy to the support properly ensures that it doesn't sag, covers the support fully and prevents damage to the plant.
Weave the length of ivy around the frame or trellis clockwise. Avoid winding tightly.
Wrap a length of garden twine around the ivy. Cross the ends of the twine between the ivy stem and the frame, then pass the twine around the frame and tie. The twine should resemble a figure-eight with the ivy in one opening of the eight and the frame in the other opening of the eight.
Tie additional lengths of twine every 12 inches, or where the ivy sags. Tie loosely and avoid bunching leaves under the twine.
Check the ties on the ivy once a month. Replace or loosen the ties if they begin to bind the growing vines. As the ivy begins to cling to the frame on its own, remove the ties.
Pinch off the tips of new vines growing beyond the frame, if desired. Alternately, weave them into the frame and tie loosely in place.
