Water generously when the top 5-7 cm of soil feels dry. Intsia bijuga prefers consistently moist conditions, especially during its establishment phase.

Reduce watering slightly during cooler, dormant periods but avoid allowing the soil to dry out completely. Ensure good drainage to prevent waterlogging.

Prune to shape the tree and remove any dead, damaged, or crossing branches. Heavy pruning is generally not necessary unless aiming for specific horticultural forms.

The best time for pruning is after flowering or in late winter before the onset of new growth. Use clean, sharp tools.

Propagation is primarily done through seeds, which often require scarification or soaking to improve germination rates. Cuttings can also be taken from mature wood, but success rates can be variable.

Grafting is another method used by enthusiasts for faster establishment and desirable traits.

Young trees may require repotting every 2-3 years, while mature specimens are best left undisturbed. Choose a pot with ample drainage holes and use a well-draining potting mix.

Repotting is best done in early spring before the active growing season begins to minimize transplant shock.
