Water: Ferocactus robustus is drought-tolerant, requiring thorough watering only when soil is dry. In spring to fall, water 1-2 times weekly; reduce in winter to once weekly. Use rainwater or distilled water to avoid mineral build-up. Avoid wetting the stem to prevent rot.

Fertilize: During growing seasons (spring, summer, fall), fertilize ferocactus robustus monthly with liquid fertilizer; winter requires none. Use low-concentrate nitrogen fertilizer for seedlings and phosphate-potassium before and after blooming. Over-fertilization can cause yellowing and slow growth; cease fertilization if this occurs.

Pruning: Ferocactus robustus, known for its spherical shape and robust spines, requires early spring pruning to remove damaged parts and promote healthy growth. Use sterilized shears to avoid infections, focusing on overgrown segments while maintaining its natural form, enhancing resilience and aesthetic appeal.

Propagation: Propagation methods for ferocactus robustus include division and grafting. For division, cut stems and plant them to encourage new shoots. Grafting involves attaching ferocactus robustus to a suitable rootstock, allowing them to join over 1-2 weeks before removing support.
