Water regularly during the growing season, especially in dry periods, ensuring the soil remains consistently moist but not waterlogged. Reduce watering in late summer and autumn as the plant enters dormancy.

In winter, water sparingly only if the soil becomes completely dry.

Prune after flowering to remove spent flower stalks and any damaged or crossing stems. Avoid cutting back the foliage until it naturally yellows and dies back in late autumn, as it provides nourishment for the roots.

Minimal pruning is generally best for this species.

Propagation is best achieved through division of established clumps in early autumn or early spring. Carefully separate root sections, ensuring each division has at least one eye and a good portion of root.

Replant immediately into well-draining soil.

Paeonia broteri generally dislikes being disturbed and is best left in situ once established. If repotting becomes absolutely necessary, do so in early autumn or early spring.

Ensure the new location provides ample space and the plant is positioned at the correct depth.
