Deadhead spent flower stalks to encourage continuous blooming and maintain a tidy appearance. In autumn, cut back the plant to the ground after flowering has finished.
This helps prevent disease and promotes vigorous new growth in spring.
Propagate by division of clumps in spring or autumn. Sow seeds in spring in a cold frame or unheated greenhouse. Cuttings can also be taken in early summer and rooted in moist, well-drained compost.
Repot young plants annually in spring to provide fresh soil and more space for root growth. Mature plants can be repotted every 2-3 years or when they become root-bound. Use a well-draining potting mix.
