- Cuttings: Softwood cuttings taken during the growing season can also be used for propagation. The cuttings should be taken from the tip of the stem, approximately 6 inches long, with at least one node. The lower leaves should be removed, and the cutting should be dipped in rooting hormone before being planted in a pot filled with well-draining soil. The cuttings should be kept moist and covered with a plastic bag to maintain high humidity until the roots develop.
- Division: The plant can be divided during the dormant season. The root ball should be carefully dug up, and the plant can be split into smaller sections with a sharp, sterilized knife. Each section should have some shoots and roots, and they can be planted in pots filled with well-draining soil.
Regardless of the propagation method used, the young plants should be kept in an area with bright, indirect light and monitored for signs of growth. Once the plant establishes itself, it can be transplanted into its final location or potted up into a larger container to allow for continued growth.
