Water: Melocactus macracanthos is drought-tolerant and needs infrequent watering. Water thoroughly when the soil is dry, ensuring proper drainage. During growing seasons (spring to fall), water once or twice weekly; in winter, reduce to about once weekly. Use rainwater or distilled water to prevent soil compaction.

Fertilize: During growing seasons (spring, summer, fall), fertilize melocactus macracanthos monthly with liquid fertilizer; avoid winter fertilization. Incorporate slow-release fertilizer when repotting. Use nitrogen fertilizer for seedlings and low-concentration phosphate-potassium before/after blooming; excessive yellowing indicates over-fertilization. Stop fertilization immediately if this occurs.

Pruning: Melocactus macracanthos is a distinct cactus featuring a notable cephalium and bright flowers. Prune in early spring to eliminate dead growth, allowing better air circulation. Minimal pruning is needed, but removing spent flowers improves aesthetics. Regular pruning promotes health and reduces pest risks.

Propagation: Melocactus macracanthos can be propagated through division and grafting. For division, cut branches and replant them to encourage new growth. Grafting involves placing melocactus macracanthos onto a suitable rootstock, securing with a rope until successful union occurs in 1-2 weeks.
