In addition to the seeding mentioned above, main propagation methods include division and grafting. To divide, cut off the tip or lateral branches of the stem with a knife and plant it in soil. After a period of time, many small shoots will grow up near the cut. When a shoot grows to proper size, it can be cut off and transplanted to form a new plant.To graft, select a suitable rootstock. Cut the tip of the rootstock, such as the stem of pitahaya (Hylocereus undatus), and then put angel's-wings, with its roots removed, in the center of the rootstock and fix it with a rope. After 1-2 weeks, the two parts grow together and the rope can be removed.
