Golden Chervil thrives in consistently moist soil, particularly during its active growth phase and dry spells. Ensure good drainage to prevent waterlogging, which can lead to root rot. Watering deeply a few times a week is generally more beneficial than frequent shallow watering, promoting deeper root development. Reduce watering significantly during its winter dormancy period.

Pruning is minimal for Golden Chervil. Deadhead spent flower stalks to prevent excessive self-seeding if not desired, or to encourage a tidier appearance. Cut back any yellowing or damaged foliage as needed throughout the growing season. In late autumn or early spring, the entire plant can be cut back to ground level to encourage fresh new growth.

Golden Chervil can be propagated by seed or by division. Seeds can be sown directly outdoors in autumn or early spring, requiring a period of cold stratification for optimal germination. For division, carefully lift mature clumps in early spring or autumn and separate them into smaller sections, ensuring each section has roots and shoots. Replant immediately.

As an outdoor perennial typically grown in the ground, repotting is not usually applicable. If grown in a container, which is less common, repot every 2-3 years into a slightly larger pot with fresh, rich potting mix. This is best done in early spring before new growth begins. Ensure the new pot has adequate drainage holes.
