3. Dip the cut end into rooting hormone powder and plant the stem into moist potting soil or vermiculite.

4. Place the pot in a bright and warm location, away from direct sunlight, and cover it with a clear plastic bag to create a mini greenhouse.

5. Water the pot regularly to keep the soil moist and mist the inside of the plastic bag to maintain humidity levels.

6. After two to four weeks, the cutting should have developed roots, and you can transplant it into a larger pot or outdoors.
