Paeonia peregrina prefers consistently moist soil but dislikes waterlogged conditions. Water deeply when the top 2-3 cm of soil feels dry, especially during dry spells and when the plant is establishing.

Reduce watering in late summer as the plant enters dormancy to prevent root rot.

Prune only to remove dead, damaged, or diseased stems. Cut back any weak or overcrowded growth in late autumn or early spring before new growth begins.

Avoid cutting back healthy stems as this can reduce future flowering. Remove spent flowers to encourage energy redirection.

Paeonia peregrina is best propagated by division in late summer or early autumn. Carefully lift the plant and divide the fleshy roots, ensuring each division has at least one bud.

Replant divisions promptly into well-prepared soil, ensuring the buds are just below the soil surface.

Established Paeonia peregrina plants are generally not conducive to frequent repotting due to their deep root systems and dislike of disturbance. If absolutely necessary, repot in autumn, handling the roots with extreme care to minimize stress and ensure prompt replanting to avoid drying out.
