Key traits and growing stats from plant data
Watering, pruning, propagation, and repotting details from plant data
Allow the soil to dry out between waterings. Overwatering is the most common cause of root rot. Water thoroughly until drainage occurs, then discard any excess water.
Reduce watering significantly during the winter dormancy period to prevent waterlogged roots.
Prune to maintain shape and encourage bushier growth. Remove any dead, damaged, or leggy stems. Cuts should be made just above a leaf node. The white sap produced is a skin irritant, so wear gloves and eye protection.
Propagate by seed or stem cuttings. Seeds germinate readily when fresh. For cuttings, allow the cut end to callus for a few days before planting in well-draining soil.
This succulent is known for its prolific seed production.
Repot every 2-3 years or when the plant becomes root-bound. Use a well-draining cactus or succulent potting mix. Choose a pot that is only slightly larger than the current one to avoid overwatering issues.
Repot in spring.
