Agonandra excelsa prefers consistently moist soil, but avoid waterlogging. Water thoroughly when the top 2-3 cm of soil feels dry. Reduce watering frequency during cooler, dormant periods in winter.

Ensure good drainage to prevent root rot, especially in container cultivation.

Prune Agonandra excelsa to maintain desired shape and size, or to remove dead, damaged, or crossing branches.

Light pruning can be done anytime, but major pruning is best done in late winter or early spring before new growth begins. Use clean, sharp tools.

Propagation is typically achieved through seeds, which may require stratification. Cuttings can also be attempted, though they may be more challenging to root.

Use a well-draining propagation mix and maintain consistent moisture and warmth for optimal results.

Repot Agonandra excelsa every 2-3 years, or when it becomes root-bound. Choose a pot that is one size larger than the current one. Use a well-draining potting mix.

Repotting is best done in early spring before the start of the active growing season.
