This distinctive feature, which develops as the plant ages, distinguishes melocactus peruvianus from its cousins and heralds maturity, signaling readiness to flower. Adapted to arid conditions, melocactus peruvianus's robust form minimizes water loss while maximizing water storage, a testament to its resilience in harsh Peruvian landscapes.

Water: Melocactus peruvianus is drought-tolerant, needing infrequent watering. Water thoroughly when soil is dry, allowing drainage. Growing seasons are spring to fall with weekly watering; reduce in winter. Use rainwater or distilled water to avoid soil compaction from tap water, and prevent water on the stem to avoid rot.

Fertilize: During growing seasons (spring, summer, fall), fertilize melocactus peruvianus monthly with liquid fertilizer; none in winter. Use slow-release fertilizer when repotting. Apply low-concentration nitrogen during seedling stages and phosphate-potassium around blooming, stopping fertilization if yellowing occurs.

Pruning: Melocactus peruvianus requires pruning in early spring to enhance growth and airflow. Use clean, sharp tools for removing dead or damaged parts, avoiding excessive pruning to minimize stress. Clean and precise cuts help maintain its aesthetic appeal and overall vitality.

Propagation: Main propagation methods for melocactus peruvianus include division and grafting. For division, cut and plant stem sections to encourage shoot growth. Grafting involves placing melocactus peruvianus on a rootstock, securing it for 1-2 weeks until they fuse.
