Water moderately during the growing season, allowing the soil to dry slightly between waterings. Reduce watering significantly in autumn and winter, providing just enough to prevent the soil from becoming bone dry.

Ensure good drainage to avoid waterlogging, which can lead to root rot.

Deadhead spent flowers to encourage further blooming and prevent self-seeding if desired. After flowering, you can trim back the plant to maintain a tidy appearance and promote bushier growth in the following year.

Remove any dead or damaged foliage as needed throughout the season.

Silene nutans can be propagated by seed, sown in autumn or early spring, either directly outdoors or in a cold frame. It can also be propagated by division of established clumps in spring or autumn.

Softwood cuttings can be taken in late spring or early summer.

Repot container-grown plants every 2-3 years in spring, or when they become root-bound. Use a well-draining potting mix, such as a blend of compost and grit or sand.

Ensure the new pot is only slightly larger than the current one to avoid excessive moisture retention.
