About Arizona barrel cactus
Ferocactus wislizeni, also known as the Fishhook Barrel Cactus, is an impressive columnar cactus native to the southwestern United States and Mexico. It is characterized by its globular to cylindrical shape, prominent ribs, and strong, hooked spines that give it its name. This cactus makes a magnificent specimen for desert gardens, rockeries, or as a focal plant in large containers, adding an architectural and rustic touch.

Care tips
It requires full, direct sun for optimal growth and abundant flowering; lack of light can lead to etiolated growth. Watering should be infrequent, allowing the substrate to dry out completely between waterings, especially in winter to prevent rot. Use a very well-draining substrate, specifically formulated for cacti and succulents. A common mistake is overwatering, which is the primary cause of death for this species.
