Watering, pruning, propagation, and repotting details from plant data
Water thoroughly when the soil is completely dry, typically in spring and summer. Reduce watering significantly in fall and winter to prevent root rot. Ensure good drainage to avoid waterlogged conditions.
Pruning is generally not required for *Mammillaria sphaerica*. Remove any dead or damaged parts carefully with sterile tools to maintain the plant's shape and health. Over-pruning can stress the plant.
Propagate *Mammillaria sphaerica* through offsets (pups) that grow around the base of the mother plant. Allow pups to dry for a few days before planting in well-draining cactus mix.
Repot every 2-3 years or when the plant outgrows its pot. Use a well-draining cactus or succulent potting mix. Choose a pot slightly larger than the current one, ensuring it has drainage holes.
