Water thoroughly when the soil is dry to the touch, typically during the growing season. Allow the soil to dry out between waterings. Reduce watering significantly in winter to prevent root rot.

Ensure good drainage to avoid waterlogged conditions, especially for potted specimens.

Pruning is generally not required for Carlina acanthifolia. Remove any dead or damaged foliage at the base of the plant to maintain a tidy appearance.

Deadheading spent flower stalks can prevent self-seeding if desired, but is not essential for plant health.

Propagation is typically done by seed sown in spring, ideally under cool conditions, or by root cuttings taken in late winter. Seeds may require a period of cold stratification. Germination can be slow and erratic.

Division of established clumps is also possible.

Repot young plants annually or bi-annually in spring, using a well-draining, gritty compost. Mature plants are best left undisturbed as they dislike root disturbance. Ensure the new pot has adequate drainage holes.

Only repot if the plant has clearly outgrown its current container.
