Water: Paeonia rockii prefers consistent watering, thriving in a balanced moisture regime. It requires weekly watering for health, especially when cultivated outdoors. Adjustments based on seasonal rainfall are crucial to meet its needs during wetter or drier periods for optimal growth.

Fertilize: Paeonia rockii requires three annual fertilizer applications to enhance flower quality: early spring, post-flower wilting, and fall/winter with organic fertilizer. Fertilize in a shallow ring, avoiding high concentrations, fecal water, and summer application to prevent damage and diseases.

Pruning: Paeonia rockii features attractive flowers and resilient growth. Prune in early spring by removing dead branches to improve air circulation and stimulate blooming. Thin interior branches for shape, but avoid over-pruning to support optimal growth. Consult horticultural guidelines for effective practices.

Propagation: Paeonia rockii is propagated via division, cutting, or sowing, with division being most common. The best time for division is fall. Use a sharp knife to split, apply sulfur powder on cuts, and let the plant dry for 1-2 days before transplanting. Allow 30-50 days in cold weather to break dormancy.
