Water thoroughly when the soil is completely dry, typically every 1-2 weeks during the growing season.

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

Pruning is generally not necessary for Mammillaria voburnensis, as it maintains a compact, clumping habit. If removing damaged or dried-out parts, use a clean, sharp knife or scissors.

Avoid excessive pruning, which can stress the plant.

Propagate by offsets or pups that naturally form at the base of the mother plant. Gently detach offsets with a sharp knife when they are a reasonable size, allow the cut surface to callous over for a few days, then pot in well-draining cactus mix.

Repot every 2-3 years or when the plant becomes pot-bound, ideally in spring. Use a gritty, fast-draining cactus potting mix. Choose a pot that is only slightly larger than the current one, ensuring good drainage holes.
