Water regularly, especially during dry periods, to keep the soil consistently moist but not waterlogged. Allow the top few centimeters of soil to dry out between waterings once established.

Reduce watering in winter as growth slows.

Deadhead spent flowers to encourage further blooming and prevent self-seeding if desired. Cut back the plant in late autumn or early spring to remove dead or damaged foliage and maintain a tidy appearance.

This also helps promote new growth.

Propagate from seed sown in autumn or early spring, either directly outdoors or in a cold frame. Division of established clumps in spring or autumn is also an effective method.

Ensure divisions have healthy roots and at least one growing point.

Pimpinella major is best left undisturbed once established. If repotting is necessary, for example, for container-grown plants, do so in early spring before new growth begins.

Use a good quality, well-draining potting mix.
