1. Select a healthy, mature plant and make a clean cut, using a sharp knife or scissors, just below a node.
2. Remove the lower leaves, leaving only two or three at the top of the stem.
3. Dip the base of the cutting in hormone rooting powder.
4. Fill a pot with well-draining potting soil and make a hole in the center.
5. Insert the cutting and gently firm the soil around it.
6. Water the cutting and cover it with a plastic bag.
7. Place the pot in a bright spot that receives indirect light.
8. Maintain the humidity inside the plastic bag and keep the soil moist but not waterlogged.
9. The cutting should root in approximately ten weeks. Remove the plastic bag and the rooted cutting can be transferred to a larger pot or planted in the ground.
