Myrtillocactus geometrizans, commonly known as Bilberry cactus, is a species of cactus native to central Mexico. Here are some general care instructions to keep your Myrtillocactus geometrizans healthy:
-
Light: Provide plenty of bright, indirect sunlight. This cactus thrives in full sun but can tolerate some shade. A southern or western-facing window is ideal if grown indoors. If grown outdoors, ensure it receives sunlight for at least 6 hours a day.
-
Temperature: Myrtillocactus geometrizans prefers warm temperatures between 21-32°C during the growing season. It can tolerate cooler temperatures down to 10°C in the winter, but prolonged exposure to frost should be avoided.
-
Watering: Allow the soil to dry out between waterings. During the growing season (spring and summer), water thoroughly when the top inch of soil feels dry. Reduce watering in the fall and winter, allowing the soil to dry out more between waterings to prevent rot.
-
Soil: Plant your Myrtillocactus geometrizans in well-draining cactus or succulent soil mix. You can also make your own mix by combining potting soil with sand or perlite to improve drainage.
-
Propagation: Myrtillocactus geometrizans can be propagated from stem cuttings. Allow the cuttings to callus for a few days before planting them in well-draining soil. Keep the soil lightly moist until new roots form.
-
Support: If your Myrtillocactus geometrizans grows tall and starts to lean, provide support with a stake to prevent it from toppling over.
