Soil Type

Water: Artichoke cactus thrives in arid conditions with minimal moisture and high drought tolerance. Water every three weeks, allowing soil to dry out completely. Ideally grown indoors, artichoke cactus requires well-draining soil to prevent root rot and support its succulent characteristics.

Fertilize: For optimal growth, fertilize artichoke cactus with specialized Succulents and Cacti Food in spring and summer, applying quarterly per package instructions. Adjust feeding in fall and pause in winter to prevent root burn. This promotes vitality and enhances blooming while avoiding over-fertilization during dormancy.

Pruning: Artichoke cactus requires minimal pruning. It is advisable to remove withered flowers and branches, allowing the plant to allocate nutrients towards healthy growth.

Propagation: Artichoke cactus is an attractive cactus known for its ribbed, artichoke-like appearance. To propagate artichoke cactus, carefully remove offsets with a clean knife and allow the cut to callous before replanting in a well-draining cactus mix for optimal success.

Repotting: Repot artichoke cactus every 2-3 years in spring to support its slow growth. Use a slightly larger pot with excellent drainage. After repotting, water sparingly, allowing soil to dry between waterings, as proper root establishment is essential for this cactus.
