Common name: Snowball. Scientific synonyms: Escobariopsis carmenae. This species is native to Northeastern Mexico. They are small cacti with an ovoid or globular body that produce suckers and reach 8 cm (3.14") in height. The axils of the tubercles are woolly and bristled and the circular areolas have abundant radial spines (100 or more) yellowish or reddish. The flowers appear around the trunk of the cactus and are white. They bloom from mid-winter to early spring. They are used in pots for patios, decks, balconies, windows and well-ventilated interiors. The Mammillaria carmenae prefers a semi-shade exposure avoiding direct sun in the central hours of the day. The temperature in winter should not be less than 5 ºC (41 ºF). The soil can be a mixture of 25% coarse sand and 75% leaf mulch or heather soil. Always water moderately, waiting until the substrate has completely dried. In late fall do not water until spring. Fertilize once with mineral cactus fertilizer in spring. They do not need pruning. The biggest enemy of these plants is excess humidity. They propagate from suckers or seeds sown in spring; it's a pretty quick process. |
