1. Select a healthy stem and make a shallow cut approximately 1/3 of the way through the stem;
2. Apply rooting hormone to the wound;
3. Wrap moist sphagnum moss around the wound site;
4. Cover the moss with plastic wrap and secure with string or twist ties;
5. Keep the moss moist and watch for root development, which should occur in 2-3 months;
6. Cut the rooted stem from the parent plant and transplant it into its permanent location.
