Water Hieronyma alchorneoides regularly, especially during establishment and dry periods. Ensure good drainage to prevent waterlogging, as the plant prefers consistently moist soil but not saturated conditions.

Reduce watering slightly during cooler, dormant periods.

Pruning is typically minimal for Hieronyma alchorneoides, primarily focused on removing dead, damaged, or crossing branches to maintain structure and health. Light shaping can be done after flowering if desired, but avoid heavy pruning to encourage natural form.

Propagation is usually done by seeds or stem cuttings. Seeds can be sown after collection.

Cuttings should be taken from healthy, semi-hardwood stems and treated with rooting hormone before planting in a well-draining medium. Maintain consistent moisture and warmth for successful rooting.

Repotting Hieronyma alchorneoides is infrequent, as it is a slow-growing tree. Young plants may require repotting every 2-3 years to ensure adequate space for root development.

Mature trees in landscape settings rarely need repotting. Use a well-draining potting mix.
