Remove the tips of new growth by pinching them between your thumb and finger. This encourages branching and bushy new growth.
Use scissors to remove damaged sections of vines and sections with few leaves, distorted leaves or leaves spaced far apart. Make the cut in a healthy part of the vine, 1/8 to 1/4 inch above a point where a leaf attaches to the vine. Cut at a slight angle, with the highest part of the cut near the leaf.
Thin out overcrowded parts of the vine, making the cuts as described above.
Reduce watering until the pruned parts of the plant begin to show new growth.
