Water thoroughly when the soil is completely dry, typically every 2-4 weeks during the growing season (spring to autumn).

Reduce watering significantly in winter, allowing the soil to dry out almost completely between waterings to prevent root rot. Ensure good drainage to avoid waterlogged conditions.

Pruning is generally not required for Echinopsis ancistrophora unless removing damaged or diseased parts. If offsets become too crowded, they can be carefully detached.

Use a clean, sharp knife for any necessary cuts to prevent disease transmission.

Propagate by offsets (pups) that naturally form at the base of the parent plant.

Carefully detach a healthy offset with a sharp knife, allow the cut surface to callus over for a few days, and then plant in well-draining cactus soil. Water sparingly after planting.

Repot young plants annually or every two years, and mature plants every 3-4 years, or when they outgrow their container. Repot in spring before new growth begins.

Use a well-draining cactus mix and a pot with drainage holes, choosing a pot only slightly larger than the current root ball.
