Water sparingly, allowing the soil to dry out completely between waterings. Overwatering is the most common cause of rot. Reduce watering significantly during winter dormancy to prevent root rot.

Ensure good drainage to avoid waterlogged conditions.

Pruning is generally not required for Parodia haselbergii. Remove any dead or damaged parts as needed to maintain the plant's health and aesthetic appearance.

Use clean, sharp tools to make precise cuts and prevent disease spread.

Propagate primarily by seed. Sow seeds in a well-draining cactus mix in spring or early summer. Keep the soil moist and warm. Offsets can also be carefully removed and allowed to callous before planting.

Repot every 2-3 years, or when the plant outgrows its pot, preferably in spring. Use a well-draining cactus or succulent potting mix. Choose a pot slightly larger than the previous one with drainage holes.
