Allow the soil to dry out completely between waterings. Ibervillea fusiformis is drought-tolerant and prone to root rot if overwatered.

Reduce watering significantly during its dormant period, typically in cooler months, to prevent fungal diseases.

Prune to manage size and shape, or to remove dead or damaged stems. Pruning can be done after flowering or in late winter before new growth begins. Sterilize pruning tools to prevent disease transmission.

Propagate from seeds sown in well-draining soil mix during spring. Seeds may require stratification. Cuttings are generally difficult to root. Patience is key as germination can be slow.

Repot only when necessary, typically every 2-3 years, in spring. Use a gritty, well-draining potting mix. Choose a pot that is only slightly larger than the current one. Handle the caudex with care to avoid damage.
