€79,50
🌱 Description
A cactus that is initially solitary and develops a characteristic dichotomous branching with age, dividing repeatedly until it forms large clusters. The stems are globose to cylindrical, blue-green, up to 15–17 cm tall and 7–11 cm in diameter. The tubercles are pyramidal, with axils covered in wool and bristles. Each areole presents about 35 spines, with 2–4 central ones that are longer and more robust, white with a dark tip. The dichotomous division of the heads, which can produce very symmetrical pairs, explains the popular name “owl eyes”.

❄️ Temperature · USDA Zone 9b

☀️ Light
Full sun or maximum brightness. High radiation promotes compact growth, the formation of dense spination, and good stem coloration. A DLI PAR of 20–30 mol/m²/day is recommended.
💧 Growth cycle and Watering
During active growth, it is recommended to water deeply and allow the substrate to dry completely before the next watering. Gradually reduce in autumn and keep dry during the winter rest.

🍽️ Nutrition
During active growth, Desert CHOICE® Cactaceae NPK (Ca-Mg) 4-4-7 (4-4) is recommended once a month along with watering. Assimilable calcium promotes the formation of firm tissues and the maintenance of turgidity, while magnesium participates in chlorophyll synthesis. Before flowering, it can be supplemented with Desert CHOICE® Flowering.
