Potting Mix and Transplanting
Use standard succulent potting mix or regular potting soil with additional sand.

- Use pruning shears to divide the plant into multiple sections.
- Ensure each section contains a portion of the root system.
- Plant the divided pieces in separate containers using standard succulent potting soil.
- Propagate in the spring for the fastest results.
To propagate with leaf cuttings, cut healthy leaves into 3″ inch sections.
Insert the lower third of each cutting into damp sand.
NOTE: Propagating with cuttings sometimes results in new plants without the marginal stripes or yellow banding.
