Product Description

Astrophytum myriostigma cv Koh-Yo RED-GREEN form CRESTED (grafted)


  • Appearance: Astrophytum myriostigma cv Koh-Yo in crested form is a unique variation of the Astrophytum myriostigma cactus, characterized by its crested or cristate growth pattern. Instead of the typical spherical or columnar shape, the crested form exhibits irregular, undulating, or fan-shaped growth.

  • Coloration: The coloration of the crested form is similar to the regular form, featuring a green to bluish-green body covered in white or yellowish flecks. The crested growth adds an additional aesthetic appeal to the plant.

  • Spines: Similar to the regular form of Astrophytum myriostigma, the crested form may have short, hair-like spines or be spineless.

  • Flowers: During the flowering season, which typically occurs in spring or early summer, Astrophytum myriostigma cv Koh-Yo in crested form may produce small yellow flowers with orange centers, adding further visual interest to the plant.

Cultivation Tips:

  1. Light: Provide bright, indirect sunlight for Astrophytum myriostigma cv Koh-Yo in crested form. Place it near a south or east-facing window where it can receive ample sunlight without being exposed to intense midday sun. Ensure some protection from scorching afternoon sunlight.

  2. Temperature: Maintain warm temperatures between 70°F to 90°F (21°C to 32°C) during the growing season. In winter, it can tolerate cooler temperatures around 50°F to 60°F (10°C to 15°C), but avoid exposing it to frost.

  3. Soil: Use a well-draining cactus mix or create a mix by combining potting soil with perlite or coarse sand. Good drainage is crucial to prevent waterlogging, which can lead to root rot, especially in the crested form.

  4. Watering: Water sparingly and allow the soil to dry out between waterings. During the active growing season (spring and summer), water when the top inch (2.5 cm) of soil is dry. Reduce watering frequency in winter to prevent overwatering, as the plant's growth slows down during this period.

  5. Humidity: Astrophytum myriostigma cv Koh-Yo in crested form doesn't require high humidity levels. It is well adapted to arid conditions and can tolerate dry indoor environments.

  6. Fertilization: Feed with a diluted, balanced cactus fertilizer during the growing season (spring and summer) following the manufacturer's instructions. Avoid fertilizing during the dormant winter months.

  7. Potting: Repot the crested form of Astrophytum myriostigma as needed, typically every 2-3 years or when the plant outgrows its current container. Use a slightly larger pot with adequate drainage holes.

  8. Pests and Diseases: Keep an eye out for common cactus pests such as mealybugs, scale insects, and spider mites. Treat any infestations promptly with insecticidal soap or neem oil. Ensure good air circulation to prevent fungal diseases.

  9. Propagation: Crested forms can be propagated by carefully removing offsets or pups that develop from the base of the plant. Allow the cuttings to callus for a few days before planting them in well-draining soil.

  10. Overwintering: During the winter months, reduce watering and provide slightly cooler temperatures to mimic the plant's natural dormancy period. Protect the crested form from frost and cold drafts.

By following these cultivation tips, you can successfully grow and care for Astrophytum myriostigma cv Koh-Yo in crested form, enjoying its unique and striking appearance in your cactus collection.
