Soil Type

Water: San diego barrelcactus is a drought-tolerant plant from arid regions, needing water just once every three weeks. It thrives with occasional rainfall, stores water in its barrel-shaped body, and is well-suited for outdoor growth in containers.

Fertilize: For optimal growth, san diego barrelcactus requires low-nitrogen 'Succulents and Cacti Food' applied quarterly during the growing season. Use one tablespoon per foot of height, avoiding the stem. Over-fertilizing risks root burn; reduce to biannual feeding in colder months and ensure well-draining soil for nutrient absorption.

Pruning: San diego barrelcactus requires minimal pruning; only remove withered flowers and branches. This practice allows the plant to allocate nutrients towards healthy growth.

Propagation: San diego barrelcactus is a slow-growing cactus suited for arid conditions. Propagation is mainly through seeds in well-draining soil, requiring moisture until germination. Established seedlings need careful transplanting, while propagation via division or cuttings is also possible but less common.
