Keep the soil consistently moist but not waterlogged. Water thoroughly when the top inch of soil feels dry. Reduce watering slightly during cooler months to prevent root rot.

Ensure good drainage to avoid standing water, which can be detrimental to the plant's health.

Prune to maintain desired shape and size, and to encourage bushier growth. Remove any dead, damaged, or crossing branches. Pinching back young shoots can promote branching. Pruning is best done in spring or early summer.

Kratom can be propagated from stem cuttings. Take 4-6 inch cuttings from healthy stems, remove lower leaves, and dip the cut end in rooting hormone.

Plant in a well-draining medium and keep moist and warm, ideally with bottom heat and high humidity.

Repot young plants annually in spring into a slightly larger container. Mature plants can be repotted every 2-3 years or when root-bound.

Use a well-draining potting mix, such as a blend of peat moss, perlite, and compost.
