Mammillaria solisioides
(Syn: Mammillaria pectinifera forma. solisioides)

CACTUSPEDIA       

 


One of the best and sought afters Mammillarias.

Description: Plants usually solitary, occasionally forming small clumps.
Stems: Spherical to depressed cylindrical, 2 - 4 (8) cm high and in diameter. Without latex. Axil: Naked
Radial spines: 25, flexible, chalky or dirty white, pectinately arranged and flattened against the stem surface, to 5 mm long.
Central spines: Not present.
Flowesr: Yellow to yellowish white, to 14 (25) mm long.
Fruits: Greenish, half-retained within the plant, barely protuding above the spines.

Propagation: Direct sow after last frost. (seldom produces offsets)

 

Cultivation: Slow growing, this plant is very rot prone and temperamental when cultivated on its own roots, but it is easy to grow if grafted. Mammillaria solisioides  has a fairly large tap root, and should be kept in a deep pot with a very draining 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. Fertilize every 2 weeks with diluted high potassium fertilizer when the plant is in bud. Light shade or full sun exposures.
