Water Calliandra riparia regularly during the growing season, keeping the soil consistently moist but not waterlogged.

Reduce watering in winter, allowing the top layer of soil to dry out slightly between waterings to prevent root rot. Ensure good drainage to avoid saturation.

Prune Calliandra riparia in late winter or early spring before new growth begins. Remove any dead, damaged, or crossing branches to maintain an attractive shape and promote airflow.

Light pruning can be done after flowering to encourage reblooming and manage size.

Propagate Calliandra riparia from seeds sown in spring or from semi-hardwood cuttings taken in summer. Seeds require warmth and consistent moisture for germination.

Cuttings should be placed in a well-draining potting mix and kept in a humid environment.

Repot Calliandra riparia every 2-3 years or when it becomes root-bound. Use a well-draining potting mix, such as a blend of potting soil, perlite, and sand.

Repot in spring, preferably before the start of the active growing season, to minimize transplant shock.
