Water Millettia brandisiana regularly, especially during its active growing season. Allow the soil to dry slightly between waterings, but avoid prolonged drought.

Reduce watering in cooler months to prevent waterlogged roots, which can lead to rot. Ensure good drainage to promote healthy root development.

Prune Millettia brandisiana to maintain shape and encourage bushier growth. Remove any dead, damaged, or crossing branches. Light pruning can be done after flowering to remove spent blooms and shape the plant.

Heavy pruning is best done in late winter or early spring before new growth begins.

Propagate Millettia brandisiana from semi-hardwood cuttings taken in summer. Select healthy shoots, make a clean cut below a node, and dip the cut end in rooting hormone.

Plant the cuttings in a well-draining potting mix and maintain high humidity until roots form. It can also be grown from seed.

Repot Millettia brandisiana every 2-3 years, or when it becomes root-bound. Choose a pot one size larger than the current one, using a well-draining potting mix.

Repotting is best done in early spring before the start of the active growing season. Ensure the new pot has adequate drainage holes.
