Water regularly, especially during dry spells, but allow the soil to dry out slightly between waterings. Avoid overwatering, as this can lead to root rot.

Established plants are relatively drought-tolerant and prefer well-drained soil.

Deadhead spent flowers regularly to encourage more blooms and prevent self-seeding if unwanted. Cut back the plant after flowering or in early spring to tidy its appearance and promote new growth.

Remove any dead or damaged stems as needed.

Rose campion is easily propagated by seed sown in spring or autumn, either directly outdoors or in a cold frame. It can also be propagated by division of established clumps in early spring or after flowering.

Cuttings can be taken in early summer.

Established plants are generally best left undisturbed in the garden. If container-grown plants become root-bound, repot in spring into a slightly larger pot using well-draining potting mix.

Ensure good drainage to prevent waterlogging.
