Water moderately during the growing season, allowing the soil to dry slightly between waterings. Reduce watering significantly in winter. Avoid overwatering, as this can lead to root rot.

Ensure good drainage to prevent waterlogged conditions, which are detrimental to Silene cretica.

Prune lightly after flowering to deadhead spent blooms and encourage reblooming. Remove any dead or leggy stems to maintain a tidy appearance and promote bushier growth.

Major pruning is generally not required, but can be done in early spring to shape the plant.

Silene cretica can be propagated from seeds sown in spring or autumn, either indoors or directly outdoors. Cuttings can also be taken in late spring or early summer from non-flowering shoots.

Ensure cuttings are planted in well-draining soil and kept moist.

Repot young plants annually in spring as needed to provide fresh soil and more space for root growth. Mature plants can be repotted every 2-3 years or when they become root-bound.

Use a well-draining potting mix and a pot that allows for adequate drainage.
