Myrtillocactus geometrizans 'Crestata'

Myrtillocactus geometrizans 'Crestata' is a unique and visually striking cultivar of the Myrtillocactus geometrizans species, commonly known as the Bilberry Cactus or Whortleberry Cactus. What sets the 'Crestata' variety apart is its growth pattern, characterized by undulating, wavy, or crested stems instead of the typical cylindrical or columnar form seen in the species.

This cultivar's crested growth is a result of genetic mutations or environmental factors during its development. The crested form can create fascinating and intricate shapes, adding an extra dimension of interest to your succulent collection or garden.

Caring for Myrtillocactus geometrizans 'Crestata' is similar to caring for the species as a whole:

1. Light: Provide bright sunlight for at least 6 hours a day. However, protect it from intense midday sun, especially in hot climates, as this can cause sunburn on the crested growth.

2. Watering: Water sparingly, allowing the soil to dry out between waterings. Overwatering can lead to root rot, especially in the crested form, as water may collect in the folds of the crest.

3. Soil: Plant your Myrtillocactus geometrizans 'Crestata' in well-draining soil. A cactus mix amended with perlite or sand works well to ensure good drainage.

4. Temperature: This cactus is cold-hardy to some extent and can tolerate temperatures down to around 20°F (-6°C). However, it's best to protect it from frost and extreme cold, especially if it's in a container.

5. Fertilization: Feed sparingly with a balanced fertilizer diluted to half strength during the growing season (spring and summer). Avoid fertilizing in fall and winter when the plant is dormant.

6. Pests and Diseases: Keep an eye out for common cactus pests such as scale insects and mealybugs. Treat any infestations promptly with insecticidal soap or neem oil.

7. Pruning: Minimal pruning is needed for Myrtillocactus geometrizans 'Crestata.' However, you may trim any dead or damaged growth to maintain its appearance.

With proper care, Myrtillocactus geometrizans 'Crestata' can thrive and become a captivating centerpiece in your succulent collection or garden, showcasing its unique and fascinating crested growth pattern.
