Key traits and growing stats from plant data
Watering, pruning, propagation, and repotting details from plant data
Water thoroughly when the top 5 cm of soil is dry, typically every 1-2 weeks during the growing season.
Reduce watering significantly in winter, allowing the soil to dry out completely between waterings to prevent root rot. Ensure good drainage.
Prune to maintain shape or remove dead/damaged stems. This is best done after flowering. Avoid excessive pruning as it can reduce future blooms. Use clean, sharp tools to make cuts just above a node or joint.
Propagate by stem cuttings. Take 15-30 cm cuttings from healthy stems in spring or summer. Allow the cut end to callus for a few days before planting in a well-draining potting mix.
Rooting typically occurs within a few weeks.
Repot every 2-3 years, or when the plant becomes root-bound. Use a well-draining cactus or succulent mix. Choose a pot only slightly larger than the previous one. Repot in spring before the active growing season begins.
