Keep the soil consistently moist, but not waterlogged, especially during the growing season. Reduce watering significantly when the plant enters dormancy. Ensure good drainage to prevent root rot.

Pruning is generally not required for Curcuma zanthorrhiza. Remove any dead or yellowing leaves as they appear to maintain plant health and appearance. The plant naturally dies back in its dormant period.

Propagation is typically done by dividing the rhizomes during repotting in spring. Ensure each division has at least one viable bud. Plant the rhizomes shallowly in well-draining soil.

Repot the rhizomes every 2-3 years in spring, or when they outgrow their container. Use a well-draining potting mix. This is also an opportunity to divide overgrown clumps.
