Water regularly, especially during dry periods, but allow the soil to dry out slightly between waterings. Avoid waterlogged conditions, which can lead to root rot. Good drainage is essential.

Reduce watering in winter when the plant is dormant.

Prune after flowering to encourage a more compact growth habit and to prevent excessive self-seeding. Deadheading spent flower spikes will prolong the blooming period and maintain a tidy appearance.

Minimal pruning is needed for established plants.

Cutleaf Selfheal is easily propagated by division of established clumps in spring or early autumn. It also readily self-seeds, and new plants can be transplanted from areas where they have naturalized.

Sow seeds indoors in early spring or directly outdoors after the last frost.

Repotting is typically only necessary for container-grown plants that have become root-bound. This is best done in spring before new growth begins. Choose a pot with good drainage and use a well-draining potting mix.

Generally, it is a low-maintenance plant that thrives when left undisturbed.
