Water sparingly, allowing the soil to dry out completely between waterings. Overwatering is the most common cause of root rot.

Reduce watering significantly during the cooler, dormant winter months to prevent fungal issues and ensure the plant's health.

Pruning is generally not required for Parodia subterranea as it is a slow-growing, clumping cactus. If any dead or damaged stems appear, they can be carefully removed with a clean, sharp knife or shears close to the base to maintain the plant's aesthetic and prevent disease.

Propagate by offsets (pups) that form around the base of the parent plant. Gently separate these offsets when they are a reasonable size and have developed some roots.

Allow the cut surface to callus over for a few days before planting in a well-draining cactus mix.

Repot only when the plant becomes pot-bound, typically every 2-3 years. Use a specialized cactus and succulent potting mix that offers excellent drainage. Repot in the spring before active growth begins.

Handle with care to avoid damaging the spines and roots.
