Keep soil consistently moist but not waterlogged, especially during the growing season. Reduce watering in cooler months, allowing the top few centimeters of soil to dry out between waterings.

Ensure good drainage to prevent root rot, as Alpinia species prefer humid conditions.

Prune to remove dead or faded flower stalks and any yellowing or damaged foliage. Cut back old stems to the ground after flowering to encourage new growth.

Heavy pruning can be done in early spring before new shoots emerge to maintain shape and size.

Propagate by division of rhizomes in spring. Carefully separate sections of the rhizome, ensuring each piece has at least one growth bud.

Replant immediately in well-draining potting mix, keeping the soil moist and warm to encourage rooting.

Repot young plants annually or when pot-bound, typically in spring. Mature plants can be repotted every 2-3 years. Use a large pot with excellent drainage and a rich, well-draining potting mix.

Ensure the rhizomes are not planted too deep.
