Water: Coryphantha poselgeriana is drought-tolerant, requiring infrequent watering. Water thoroughly when the soil is dry, and use rainwater or distilled water. In growing seasons, water weekly; in winter, reduce to once weekly, avoiding water on the stem to prevent rot.

Fertilize: During growing seasons (spring, summer, fall), fertilize coryphantha poselgeriana monthly with liquid fertilizer; avoid in winter. Use nitrogen during seedling stages and phosphate-potassium around blooming. Apply low-concentration fertilizers multiple times instead of high concentration. If yellowing occurs, cease fertilization immediately.

Pruning: Coryphantha poselgeriana is a unique succulent characterized by dense spines and vibrant yellow flowers. Prune in early spring to promote growth and flowering, trimming dead parts carefully. Light, regular pruning enhances shape and aesthetics, while sterilized tools reduce infection risk and improve vigor and resilience.

Propagation: Propagation of coryphantha poselgeriana can be achieved through division or grafting. For division, cut the stem and plant it to encourage new shoots. In grafting, place coryphantha poselgeriana onto a rootstock, securing with a rope for 1-2 weeks until they fuse together.
