The myrtillocactus , a native North American cactus genus, requires low-maintenance care. Basic needs include full sun, infrequent watering after initial rooting, and well-draining soil. It prefers temperatures over 50°F (10°C). Challenges include common pests like mealybugs and scale, as well as root rot from overwatering. Seasonally, minimal watering is needed in winter, while plentiful sunlight and warmth boost its summer growth. Cold, wet conditions are potentially detrimental, making indoor care a consideration during harsh winters.
