Mammillaria gracilis, is a small cactus with somewhat slender, cylindrical, bright green body clustering and branching freely, but the offsets easily detached. The offsets are easily knocked off so the plant must be handled with care; however, these offsets quickly root if placed on the ground. The tubercles are roundish, each being tipped by stiff white spines, radiating like a star, making the plant look lace-covered. There are one or more longer dark-brown central spines. Creamy white, bell-shaped flowers appear in spring or in late summer-autumn. Eventually, this cactus forms a large, rounded clumps.
Mammillaria species like most cacti they're drought tolerant and need very little care and attention to grow well . Plenty of sunshine will keep this cacti more than happy. Provide bright, even light to encourage tight growth and flowering. Some shade during a hot summers day can be helpful to prevent sunburn.
Allow the soil mix to become nearly dry between watering, but then water thoroughly. Suspend watering in the winter, but mist occasionally. Not enough sunlight and over-watering are common mistakes.
Use pot with good drainage and a very porous potting media.
Feed every 4 weeks with a high potassium fertiliser during summer
