Water Adonis amurensis regularly, especially during dry periods, ensuring the soil remains consistently moist but not waterlogged. Allow the top inch of soil to dry out slightly between waterings to prevent root rot.

Reduce watering in autumn as the plant goes dormant.

Pruning is generally not required for Adonis amurensis beyond removing any dead or damaged foliage at the end of the growing season. If overcrowding occurs, thinning can be done after flowering.

Avoid cutting back green foliage, as it is necessary for photosynthesis and storing energy.

Propagate Adonis amurensis by seed, which requires a period of cold stratification. Sow seeds in autumn in a well-drained, moist medium and leave outdoors to experience winter conditions.

Division of established clumps can also be done in early spring, but care must be taken not to disturb the roots.

Repotting Adonis amurensis is infrequent, typically every 3-5 years, or when the plant becomes root-bound. Perform this in early spring before active growth begins or in late autumn after flowering.

Use a well-draining, humus-rich soil mix and handle the root system gently.
