Take 10-15 cm cuttings of new growth from the plant, ensuring that there are no flowers or buds on the cutting. Remove the leaves from the bottom half of the cutting and dip the cut end in rooting hormone. Plant the cutting in a well-draining potting mix, and water it thoroughly. Cover the pot with a clear plastic bag to keep the moisture in and place it in a warm and bright location but not in direct sunlight. In about 4-6 weeks, the cutting should start to show signs of new growth, which signals that it has rooted successfully. Once the plant has sufficient growth, it can be transplanted into a larger pot or planted in a permanent location.
