Mammillaria, a popular cacti genus, is characterized by low-maintenance care. It requires bright light, adequate ventilation, and well-draining soil, with occasional watering and a warm temperature range above 10°C (50°F). Common challenges include rot (from wet, stagnant conditions), and pests like mealybugs and mites. Seasonally, mammillaria requires less watering in winter, with a dry dormancy period. In summer, protect from intense midday sun. Spring sees prolific flowering with regular watering. Overall, this genus balances ease of care with special attentiveness to watering and protection from extreme conditions.
