Water Xerosicyos perrieri sparingly, allowing the soil to dry out completely between waterings. Overwatering is detrimental and can lead to root rot.

Reduce watering significantly during the dormant winter months to mimic its natural arid habitat.

Pruning Xerosicyos perrieri is generally minimal. Remove any dead, damaged, or leggy stems to maintain a tidy appearance and encourage bushier growth.

Pruning can be done at any time, but is best done after flowering or before the active growing season.

Propagate Xerosicyos perrieri from stem cuttings. Take cuttings during the active growing season and allow them to callus for a few days before planting in a well-draining medium. Rooting hormone can be beneficial.

Patience is key as it can be slow to root.

Repot Xerosicyos perrieri every 2-3 years, or when it becomes root-bound. Use a well-draining succulent or cactus potting mix. Choose a pot that is only slightly larger than the current one.

Repotting is best done in spring.
