Water regularly to keep the soil consistently moist but not waterlogged. Allow the top few centimeters of soil to dry out slightly between waterings, especially during warmer months.

Reduce watering in cooler periods to prevent root rot. Ensure good drainage in pots.

Pruning is generally minimal for Caryota cumingii. Remove dead, damaged, or diseased fronds as needed by cutting them at the base. This helps maintain the plant's appearance and health.

Avoid excessive pruning, as it can stress the plant.

Propagation is typically done by seed. Sow seeds in a well-draining, sterile seed-starting mix. Keep the soil consistently moist and warm, ideally around 25-30°C.

Germination can be slow and irregular, sometimes taking several months.

Repot young plants annually or when root-bound, typically in spring. Mature plants can be repotted every 2-3 years. Use a well-draining potting mix.

Choose a pot that is only slightly larger than the current one to avoid overwatering issues.
