Keep the soil consistently moist but not waterlogged. Water thoroughly when the top 2-3 cm of soil feels dry. Reduce watering slightly during cooler months, but never allow the soil to dry out completely.

Ensure good drainage to prevent root rot.

Pruning is generally minimal for Etlingera australasica. Remove spent flower stalks and any dead or damaged leaves at their base. This helps maintain a tidy appearance and encourages new growth and flowering.

Propagation is best achieved through division of established rhizomes in spring. Carefully separate sections of the rhizome, ensuring each piece has at least one shoot and some roots.

Replant immediately into well-draining potting mix.

Repot every 2-3 years, or when the plant becomes pot-bound. Spring is the ideal time to repot. Use a well-draining potting mix, such as a blend of peat, perlite, and compost.

Choose a pot that is slightly larger than the current one.
