How to grow Fishhook Barrel Cactus in Tucson & the low desert
Watering
No supplemental water needed once established; native rainfall is sufficient. Water young transplants deeply but infrequently in the warm season and keep dry in winter to prevent rot.
Fertilizer & nutrients
Not required; thrives in lean native soils. Avoid fertilizing.
Pruning & care
None; remove only dead or rotted tissue.
Notes
Named for its stout, flattened, hooked ('fishhook') central spines. Older plants often lean toward the south/southwest, contributing to the 'compass barrel' nickname. One of the most common native barrels around Tucson. Produces persistent yellow, pineapple-shaped fruit at the crown.
