Water moderately during the growing season (spring to fall), allowing the soil to dry slightly between waterings. Reduce watering significantly in winter to prevent root rot.

Ensure good drainage to avoid waterlogged conditions, as Rohdea japonica prefers to be on the drier side.

Prune only to remove dead, damaged, or yellowing leaves. Cut these back to the base of the plant using clean, sharp scissors or pruning shears.

Avoid heavy pruning, as this plant generally requires minimal shaping and grows slowly.

Propagate by division of rhizomes in spring or by seed. Seed propagation can be slow, and seedlings may not come true to type. Divisions are the most reliable method for obtaining new plants with similar characteristics.

Repot every 2-3 years or when the plant becomes root-bound, preferably in spring. Use a well-draining potting mix.

Choose a pot that is only slightly larger than the current one, as Rohdea japonica prefers to be slightly crowded.
