Water
Water sparingly, allowing the soil to dry out completely between waterings. Overwatering is detrimental, especially during dormancy. Reduce watering significantly in cooler months to prevent root rot.
Ensure pots have excellent drainage.

Watering, pruning, propagation, and repotting details from plant data
Water sparingly, allowing the soil to dry out completely between waterings. Overwatering is detrimental, especially during dormancy. Reduce watering significantly in cooler months to prevent root rot.
Ensure pots have excellent drainage.
Prune sparingly to maintain shape or remove dead/damaged foliage. Pruning is generally not required for Raphionacme caerulea as it is slow-growing.
If pruning is necessary, use clean, sharp tools and allow cuts to callus before watering.
Propagate from seed or stem cuttings. Seeds require warm, consistently moist conditions to germinate. Cuttings should be taken during the active growing season, allowed to callus, and then planted in well-draining soil.
Repot infrequently, only when the plant is severely root-bound, typically every 2-4 years. Use a gritty, well-draining potting mix. Repot in spring just as active growth begins.
Handle the tuberous root carefully to avoid damage.
