Care tips

This cactus requires full, direct sun for optimal growth and healthy flowering. Watering should be sparse, allowing the substrate to dry out completely between waterings, especially in winter to prevent rot. Use a very well-draining substrate, specifically for cacti, with plenty of mineral material. A common mistake is overwatering, which can be fatal for this drought-tolerant species.
