Water Helianthemum X thoroughly when the top 2-3 cm of soil feels dry. Avoid overwatering, as this can lead to root rot.

During winter dormancy, reduce watering frequency significantly, allowing the soil to dry out more between waterings to prevent waterlogged conditions.

Prune Helianthemum X after flowering to maintain a tidy shape and encourage bushier growth. Remove spent flower stalks and any leggy or dead stems.

Light pruning can be done in early spring to remove winter damage and shape the plant.

Propagation is typically done by semi-hardwood cuttings taken in late summer or early autumn. Insert cuttings into a well-draining potting mix and keep them moist in a protected environment until they root.

Seeds can also be sown in spring, but may not come true to type.

Helianthemum X prefers to be slightly pot-bound and does not require frequent repotting. Repot only when the plant has clearly outgrown its container, typically every 2-3 years.

Use a well-draining potting mix and choose a pot only slightly larger than the current one.
