Water: Adapted to desert conditions, emory's barrel cactus is drought-tolerant, needing water only every 2-3 weeks. Thriving in full sun, it benefits from consistent, infrequent watering during peak growing season to promote flowering while avoiding root rot.

Fertilize: Fertilize emory's barrel cactus monthly with liquid fertilizer during growing seasons (spring, summer, fall), avoiding winter. Incorporate slow-release fertilizer when repotting. Use low-concentration nitrogen fertilizer for seedlings and phosphate-potassium before/after blooming; excessive fertilizer can cause yellowing and slow growth, requiring cessation of fertilization.

Pruning: Emory's barrel cactus requires minimal pruning, best done in early to late winter to remove dead or damaged parts. Light pruning enhances air circulation and reduces disease risk. Always use sterilized tools to prevent infections, ensuring vibrant and robust growth for optimal plant health.

Propagation: Emory's barrel cactus thrives in arid regions with its stout, ribbed stem and spines. Propagation via cuttings requires clean tools, allowing the cut to callous before potting in well-draining soil. Warm temperatures and indirect light boost rooting, while misting aids development, avoiding overwatering to prevent rot.
