New plants will begin to grow from the base of the leaf in a few weeks.
Propagation by Division
Propagation by division is a method used for mature plants or if you want to create new plants from an existing plant. Carefully uproot the plant and divide it into smaller sections. Each section should have at least one stem and a healthy root system. Plant the divided sections in a well-draining soil mix and water sparingly. Keep the plants in a warm and bright area.
