How to Grow and Care

Easy to grow and commonly cultivated, most mammillaria cacti tend to be small and spherical with dense hairs or spines, which has given them the nickname “puff-ball cactus.”

All cacti need well-drained soil, but it’s especially crucial for mammillaria species—cactus fans will often call them “mamms” for short—as they tend to be prone to root rot due to their shape and size.
For beginners, a commercial cactus mix is often your best bet. 

Certainly, if you’re buying pre-mixed potting soil, make sure you’re choosing a cactus-friendly mix. Cacti do not require lots of extra nutrients, so look for a mix without built-in fertilizer...– See more at:HOW TO GROW AND CARE FOR MAMMILLARIA
