Cultivation
Mammillaria hahniana is one of several Mammillaria species to be cultivated. In temperate regions it must be grown under glass with heat. However, some growers report that it is quite hardy down to −5 °C (23 °F) or even −10 °C (14 °F). Like all cacti it must be kept dry in winter, and fed and watered during the active growth cycle in summer. Increasing quite readily and flowering at a relatively early age, it is a suitable subject for domestic cultivation.[3] It has gained the Royal Horticultural Society's Award of Garden Merit.[4][5]
