Water
Water thoroughly when the soil is completely dry. Reduce watering significantly in winter to prevent rot. Ensure excellent drainage; never let the plant sit in water.
Overwatering is the most common cause of death for this species.

Pruning is typically not necessary for aesthetic reasons unless removing damaged or diseased parts. If offsets become too crowded, they can be gently detached. Clean tools are essential to prevent disease.
Propagate primarily through offsets (pups) that naturally form at the base. Gently detach offsets with a clean knife and allow them to callus for a few days before planting in well-draining cactus mix.
Repot every 2-3 years or when the plant outgrows its pot, preferably in spring. Use a gritty, fast-draining cactus or succulent mix. Choose a pot only slightly larger than the current root ball.
