Water regularly during the growing season, allowing the soil to dry slightly between waterings. Reduce watering in autumn and winter, as the plant becomes dormant.

Ensure good drainage to prevent root rot, especially in containers.

Deadheading spent flower stalks encourages secondary blooms and prevents self-seeding. Cut back dead foliage in late winter or early spring before new growth emerges. Remove any diseased or damaged parts promptly.

Fuller's Teasel is easily propagated by seed. Sow seeds directly outdoors in early spring or autumn. They can also be started indoors a few weeks before the last frost.

Division of established clumps is also possible in spring.

Repot young plants as needed, typically every one to two years, into slightly larger containers. Mature plants are often best left undisturbed or divided rather than repotted.

Ensure the new pot has adequate drainage holes.
