Water: Anchor plant thrives in arid environments, demonstrating high drought tolerance with minimal watering needed once established, ideally every two weeks. It prefers well-draining soil and is commonly found in rock gardens, showcasing its resilience and low-maintenance nature regarding hydration.

Fertilize: Anchor plant benefits from semi-annual fertilization using balanced fertilizers to enhance growth and flowering. Apply in spring and fall, being cautious with dosage to prevent growth issues. Ensure soil is moist beforehand for optimal nutrient absorption and protect roots from fertilizer burn.

Pruning: Anchor plant features thorny branches and needs selective pruning for health and form. Prune in early spring, removing dead or overcrowded branches to enhance air circulation and minimize disease. Regular pruning maintains shape and prevents overgrowth, preserving its landscape appeal.

Propagation: Anchor plant features sharp, spine-like foliage and is propagated mainly through cuttings. To ensure success, use rooting hormone, plant in well-draining soil, and maintain moisture without waterlogging. A warm, sheltered location promotes faster root growth, facilitating easier incorporation into collections.
