Water
Water thoroughly when the soil is completely dry. Reduce watering significantly in winter dormancy. Overwatering leads to root rot, which is fatal for Mammillaria decipiens. Ensure good drainage to prevent waterlogging.

Watering, pruning, propagation, and repotting details from plant data
Water thoroughly when the soil is completely dry. Reduce watering significantly in winter dormancy. Overwatering leads to root rot, which is fatal for Mammillaria decipiens. Ensure good drainage to prevent waterlogging.
Pruning is generally not required for Mammillaria decipiens. Remove any dead or damaged parts with a clean, sharp knife or shears. This helps maintain the plant's aesthetic and prevents disease.
Propagate primarily through offsets (pups) that naturally form around the base of the parent plant. Allow offsets to dry for a few days before planting in well-draining cactus mix.
Repot every 2-3 years, or when the plant outgrows its container. Choose a pot slightly larger than the previous one. Use a gritty, well-draining cactus soil mix. Repot in spring.
