Pterolobium hexapetalum prefers consistently moist soil, especially during its active growth period. Water thoroughly when the top 2-3 cm of soil feels dry.

Reduce watering in cooler months, allowing the soil to dry out slightly more between waterings. Avoid waterlogging, which can lead to root rot.

Prune Pterolobium hexapetalum in late winter or early spring before new growth begins. Remove any dead, damaged, or crossing branches to maintain plant health and shape.

Light trimming can be done throughout the growing season to encourage bushier growth and control size if necessary.

Pterolobium hexapetalum can be propagated from seeds sown in spring, often requiring scarification or stratification to improve germination rates. Cuttings can also be taken from semi-hardwood in summer and rooted in a well-draining medium, though seed propagation is more common and generally more successful.

Repot Pterolobium hexapetalum every 2-3 years, or when it becomes root-bound. Use a well-draining potting mix. The best time to repot is in spring, just as the plant begins its active growth phase.

Choose a pot that is only slightly larger than the current one to avoid overwatering issues.
