Allow the soil to dry out between waterings, particularly in winter. Overwatering can lead to root rot. Water thoroughly when the top 2-3 cm of soil feels dry to the touch.

Reduce watering significantly during cooler months to mimic its natural dormancy.

Prune lightly after flowering to maintain a compact shape and encourage bushier growth. Remove any dead or weak stems at any time of the year.

Avoid heavy pruning, especially in late autumn, as this can make the plant susceptible to frost damage.

Sideritis scardica is best propagated from seeds sown in spring or from stem cuttings taken in late spring or early summer. Cuttings should be treated with rooting hormone and planted in a well-draining medium.

Seeds require stratification for best germination.

Repot young plants annually or every two years in spring. Mature plants can be repotted less frequently, only when root-bound.

Use a well-draining potting mix, such as a cactus or succulent blend, to ensure good aeration and prevent waterlogging.
