Water regularly during the growing season, ensuring the soil remains consistently moist but not waterlogged. Reduce watering in fall and winter, allowing the soil to dry out slightly between waterings.

Avoid overhead watering to prevent fungal diseases. Proper drainage is crucial to prevent root rot.

Prune in late winter or early spring before new growth emerges. Remove any dead, damaged, or crossing branches. Light pruning can also be done after flowering to maintain shape and encourage bushier growth.

Avoid heavy pruning, as it can stress the plant.

Propagation is typically done through seeds sown in autumn or early spring. Alternatively, cuttings can be taken in late spring or early summer and rooted in moist potting mix.

Ensure cuttings are from healthy, disease-free parent plants for best results.

Iva hayesiana is not typically a plant that requires frequent repotting. If grown in a container, repot only when root-bound, usually every 2-3 years, in the spring before active growth begins.

Use a well-draining potting mix and a slightly larger container.
