Water Mussaenda afzelii regularly, keeping the soil consistently moist but not waterlogged. Allow the top inch of soil to dry out slightly between waterings. Reduce watering during cooler months to prevent root rot.

Ensure good drainage to avoid standing water.

Prune Mussaenda afzelii in late winter or early spring to shape the plant and encourage bushier growth. Remove any dead, damaged, or crossing branches.

Pruning after flowering can also help maintain its form and promote further blooms.

Propagate Mussaenda afzelii from semi-hardwood cuttings taken in late spring or early summer. Dip cuttings in rooting hormone and plant them in a well-draining potting mix.

Maintain high humidity and warmth until roots develop.

Repot Mussaenda afzelii 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.

Repotting is best done in spring before new growth begins.
