It requires direct or very bright sunlight to maintain its intense blue coloration and compact growth. Watering should be infrequent, allowing the substrate to dry out completely between waterings to prevent root rot; it is very drought-tolerant. Use a well-draining substrate specifically formulated for cacti and succulents. A common mistake to avoid is overwatering, which can be fatal for this species.
