Crateva magna prefers consistently moist soil, especially during its active growth period. Water deeply 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, but avoid complete desiccation.

Prune Crateva magna in late winter or early spring before new growth begins. Remove dead, damaged, or crossing branches to maintain structure and encourage vigorous flowering.

Light pruning can be done after flowering to shape the plant and remove spent flower clusters.

Propagation is typically done from seed, which requires stratification or a period of cold treatment before sowing. Cuttings can also be taken from semi-hardwood in summer.

Ensure cuttings are treated with rooting hormone and kept in a humid environment to encourage root development.

Young Crateva magna plants benefit from repotting every 1-2 years in early spring. Mature plants can be repotted less frequently, every 3-4 years, or when root-bound.

Use a well-draining potting mix and a slightly larger pot to accommodate growth.
