To propagate from stem cuttings, take a cutting that includes a node (the bump where leaves are attached) and at least two leaves. Cut just below a node with a sharp knife or pruning shears. Remove the bottom leaves so that only two leaves remain on the cutting. Stick the cutting into a pot of moistened potting mix. Be sure to bury the node in the potting mix. Place the pot in a warm, bright location but out of direct sunlight. Keep the potting mix moist but not soggy. New roots should form within 4-6 weeks. To propagate by air layering, choose a stem that is at least 18 inches long. Make a cut in the stem about halfway between a leaf node and the tip of the stem. Dust the cut with rooting hormone powder. Wrap the stem with moistened sphagnum moss and then cover the moss with plastic wrap, securing it in place with tape. Make sure the plastic wrap is tight against the stem so that no air can get in. Place the stem in a bright, warm location but out of direct sunlight. Keep the moss moist. New roots should form within 4-6 weeks. Once the roots have formed, cut the stem below the plastic wrap and pot up the new plant.
