Acanthocereus Tetragonus, commonly known as the Fairy Castle Cactus, is a beautiful succulent that captures the imagination with its unique architectural form. This enchanting cactus resembles a miniature castle. Let’s delve into the world of Acanthocereus Tetragonus and explore the fascinating features that make it a favorite among succulent enthusiasts.

Unique Structure

The Fairy Castle Cactus boasts an extraordinary growth habit that resembles a whimsical castle. It features multiple upright, columnar stems that branch out in a way that resembles turrets and towers. This intricate branching pattern creates a stunning focal point in any succulent display.

Spiky Appeal

Acanthocereus Tetragonus is adorned with sharp spines lining its ridged stems. These spines serve as a protective mechanism and enhance the cactus’s captivating aesthetic. They add a sense of drama and texture to its overall appearance.

Growth and Size

While the Fairy Castle Cactus starts as a small plant, it can grow to impressive heights. It can reach several feet tall with proper care and time, making it a commanding presence in any succulent arrangement.

Cultivation and Care

Taking care of Acanthocereus Tetragonus requires attention to its specific needs. Here are some essential care tips:

  • Light: Provide your Fairy Castle Cactus with bright, indirect sunlight. It can tolerate direct sunlight, but be cautious of scorching its delicate stems.
  • Temperature: This cactus thrives in warm temperatures, ideally 18°C – 29°C (approximately 64.4°F – 84.2°F). Don’t let this plant alone under freezing temperatures.
  • Watering: Make sure the soil is dry and water sparingly. As I said in many posts on Succulent City, we should avoid root rot at all costs.
  • Soil: Use a well-draining cactus or succulent potting mix. Good drainage is essential to prevent soggy roots.
  • Fertilization: Feed your Fairy Castle Cactus with a balanced, diluted cactus fertilizer during the growing season. Follow the instructions on the fertilizer package.
  • Propagation: Acanthocereus Tetragonus can be propagated from stem cuttings. Before planting them, allow the cuttings to callus for a few days.
  • Maintenance: Inspect your Fairy Castle Cactus for pests and remove dead or damaged stems. Handle the cactus with care due to its spines.
