Watering

The Bishop’s Cap Cactus requires minimal watering. It’s crucial to let the soil dry out completely between watering sessions to prevent root rot. During the growing season (spring and summer), water the cactus every two to three weeks. In the dormant season (fall and winter), reduce watering to once a month or less.

Light

This cactus thrives in bright light. Ideally, it should receive direct sunlight for at least six hours a day. If grown indoors, placing it near a south-facing window will provide ample light. Insufficient light can lead to weak growth and loss of the cactus’s characteristic shape.

Temperature

Astrophytum Myriostigma prefers warm temperatures. It grows best in temperatures ranging from 70°F to 85°F (21°C to 29°C). In winter, it can tolerate cooler temperatures down to 50°F (10°C) but should be protected from frost and freezing conditions.

Soil Mix

A well-draining soil mix is essential for the Bishop’s Cap Cactus. A combination of cactus potting mix and perlite or coarse sand works well to ensure proper drainage. Avoid using regular garden soil, which retains too much moisture and can lead to root rot.

Humidity

This cactus is well-adapted to dry conditions and does not require high humidity. It thrives in typical indoor humidity levels and does not need any special adjustments. High humidity can increase the risk of fungal infections and should be avoided.

Fertilizer

Fertilize the Bishop’s Cap Cactus sparingly. During the growing season, apply a diluted cactus fertilizer once a month. Over-fertilizing can harm the plant, so it’s better to err on the side of caution and use less than more.

Toxicity

Astrophytum Myriostigma is non-toxic to humans and pets, making it a safe addition to homes with children and animals. However, it's always best to prevent ingestion as a precaution.

The Astrophytum Myriostigma, with its unique star-shaped form and easy care requirements, is an excellent choice for both novice and experienced plant enthusiasts. By providing the right conditions in terms of watering, light, temperature, soil mix, and humidity, you can ensure this captivating cactus thrives in your care.
