Water regularly during the growing season, allowing the soil to dry out slightly between waterings. Reduce watering in winter to prevent waterlogging.

Ensure good drainage to avoid root rot, as this plant is relatively drought-tolerant once established.

Pruning is typically minimal for Hairy Cat's Ear. Deadheading spent flower stalks can prevent unwanted self-seeding and maintain a tidier appearance.

Remove any yellowing or damaged leaves as they appear to promote healthy foliage growth and plant vigor.

Hypochaeris radicata is easily propagated by seed. Sow seeds in spring or autumn in well-draining soil. It can also spread readily via rhizomes, and established plants can be divided in spring or autumn for propagation.

Repotting is rarely necessary for Hypochaeris radicata as it is often grown as ground cover or in rock gardens. If grown in a container and it becomes root-bound, repot in spring to a slightly larger container with fresh, well-draining potting mix.
