Keep the soil consistently moist during the growing season, but avoid waterlogging. Reduce watering significantly during the dormant period in cooler months, allowing the soil to dry out slightly between waterings.

Ensure good drainage to prevent root rot.

Pruning is generally not required for Pterygota alata. If necessary, remove any dead, damaged, or crossing branches to maintain the tree's natural shape.

Pruning can be done in late winter or early spring before new growth begins.

Propagate Pterygota alata from seeds, which require warm conditions and consistent moisture to germinate. Cuttings can also be taken from semi-hardwood in summer, but rooting can be slow and challenging.

Seed propagation is the more common method.

Young plants benefit from repotting every 2-3 years in spring to provide fresh soil and more space for root growth. Mature trees are generally best left in place unless rootbound. Use a well-draining potting mix.
