Water
Use the soak and dry method and reduce water sharply during winter dormancy.

Temperature
Protect the plant as temperatures approach 30°F (-1.1°C).

Propagation
- Wear nitrile gloves and choose a healthy offset or stem.
- Cut cleanly and rinse tools after contact with sap.
- Let the cut surface dry and callous.
- Plant in dry, well-draining soil.
- Delay watering until roots begin to form.
