This species is easy and well worth growing. It requires little care once they have reached a nice flowering size. Hamatocactus setispinus is suited for any rich, well-drained soil in full sun throughout the year (but does better with some light shade in the summer).
This plant needs plenty of water (indicatively to about once a week). Avoid wetting the bodies of these plants while they are in sunlight. A wet cactus in the sunlight can cause sun burning which can lead to scars or even fungal infections and death.
