Water deeply when the top 5-7 cm of soil feels dry. Avoid waterlogging, as Sideritis dasygnaphala prefers well-draining conditions. Reduce watering significantly during winter dormancy to prevent root rot.

Ensure good drainage in pots or garden beds.

Prune lightly after flowering to maintain a tidy shape and encourage bushier growth. Remove any dead, damaged, or crossing stems. Avoid heavy pruning, especially into old wood, as it may not regrow.

Minimal pruning is generally sufficient.

Propagate from semi-hardwood cuttings taken in late summer or early autumn. Dip cuttings in rooting hormone and plant in a well-draining, sterile potting mix. Keep moist and provide bottom heat for best results.

Alternatively, sow seeds in spring.

Repot Sideritis dasygnaphala every 2-3 years, or when it becomes root-bound. Use a well-draining potting mix, such as a cactus or succulent blend, possibly with added grit. Repot in spring before active growth begins.
