Dalbergia antsirananae prefers consistently moist soil but not waterlogged conditions. Water thoroughly when the top 2-3 cm of soil feels dry.

Reduce watering frequency during the dormant winter months, allowing the soil to dry out slightly more between waterings to prevent root rot.

Pruning is generally minimal for Dalbergia antsirananae, primarily focused on removing dead, damaged, or crossing branches to maintain plant health and shape. Light pruning can be done in late winter or early spring before new growth begins to encourage bushier growth.

Propagation of Dalbergia antsirananae is typically achieved through stem cuttings taken in spring or summer. Use a rooting hormone to improve success rates and plant the cuttings in a well-draining potting mix.

Maintain high humidity and warmth for optimal rooting.

Repot Dalbergia antsirananae every 2-3 years, or when it becomes root-bound. Use a well-draining potting mix, such as a combination of peat moss, perlite, and sand.

Repotting is best done in the spring before the active growing season commences.
