Mammillaria carmenae is a compact, globular cactus species native to the mountainous regions of Tamaulipas, Mexico. Its dense covering of fine, golden-yellow or white spines gives it a soft, woolly appearance, making it a delightful addition to any cactus collection. Over time, this species forms small clumps, adding to its ornamental appeal.
During the spring and early summer, Mammillaria carmenae produces a crown of small, bell-shaped flowers in shades of pink or white. Its manageable size and charming aesthetics make it a favorite among both beginner and experienced growers.
Care Tips:
- Light: Provide bright, indirect light. It can tolerate some direct sun but may need protection during peak sunlight hours to avoid scorching.
- Watering: Allow the soil to dry completely between waterings. Water sparingly in winter, as it enters dormancy.
- Soil: Use a well-draining cactus soil mix with added sand or perlite.
- Temperature: Thrives in temperatures between 20°C and 30°C (68°F to 86°F). Protect from frost and maintain above 10°C (50°F).
- Fertilizer: Feed with a diluted cactus fertilizer once a month during the growing season (spring and summer). Avoid fertilizing in winter.
- Repotting: Repot every 2-3 years, or when it outgrows its container. Use fresh, well-draining soil.
- Propagation: Easily propagated through offsets or seeds.
