Keep the soil consistently moist but not waterlogged, especially during the growing season. Water thoroughly when the top centimeter of soil begins to feel dry.

Reduce watering slightly during cooler months, allowing the soil to dry out a bit more between waterings to prevent root rot.

Pruning Amomum glabrum is primarily for aesthetic purposes and to manage size. Remove any dead, damaged, or yellowing leaves as they appear. Trim back overgrown stems to maintain a compact shape.

Pruning can be done anytime, but major pruning is best done in late spring after flowering.

Amomum glabrum can be propagated by division of rhizomes. In spring, carefully divide the mature rhizomes into smaller sections, ensuring each section has at least one growth bud.

Replant the divisions in well-draining soil, keeping them consistently moist until established.

Repot Amomum glabrum every 2-3 years or when it becomes root-bound. Choose a pot that is slightly larger than the current one. Use a well-draining potting mix, such as a blend of peat moss, perlite, and compost.

Repotting is best done in early spring before new growth begins.
