Mammillaria moelleriana

M. moelleriana is a small cactus that appears above the ground as a squat, spherical stem, completely covered by very strong hooked spines, and usually solitary. In cultivation the plant's stem may be cylindrical. It is also one of the more difficult to grow, as it is subject to losing its roots.
Flowers: White or light pink flowers with darker midveins, up to 1.8 cm in diameter.

Cultivation: One of the more difficult species to grow, this plant is very rot prone and temperamental when cultivated on its own roots, but it is easy to grow if grafted. It should be kept in a deep pot with a very loose and open potting mineral substrate. Watering during the active growing season (spring and summer), this will encourage steady growth. But be careful with watering, which all thick rooted species require (rot sensitive). Keep dry during the winter rest. Strong filtered light will encourage the formation of heavy spination.
Light shade or full sun exposures.
