Water thoroughly when the soil is completely dry. Allow the soil to dry out between waterings to prevent root rot.

Reduce watering significantly during the cooler winter months, providing only enough to keep the plant from shriveling. Overwatering is the most common cause of death for this cactus.

Pruning is generally not required for aesthetic reasons unless removing damaged or dead segments. If you need to control size or shape, use a clean, sharp knife or shears.

Allow cuts to callus over for a few days before replanting or disturbing the soil. Pruning can also be done for propagation.

Propagate by stem cuttings. Allow cuttings to dry and callus over for several days to a week before planting in well-draining cactus soil. Roots typically form within a few weeks.

Keep the soil slightly moist but not wet until roots are established. This species can also be grown from seed.

Repot when the plant becomes root-bound, typically every 2-3 years. Use a well-draining cactus or succulent mix. Choose a pot only slightly larger than the current one, with drainage holes.

Repot in the spring or early summer, after the risk of frost has passed. Handle with care due to spines.
