Water regularly to keep the soil consistently moist, especially during dry periods. Avoid waterlogging, as this can lead to root rot. Allow the top inch of soil to dry slightly between waterings once established.

Cut back flowering stems after blooming to encourage a tidier appearance and potentially a second flush of flowers. In late autumn or early spring, remove dead or damaged foliage to maintain plant health and prevent disease overwintering.

Easily propagated by division of established clumps in early spring or autumn. Stem cuttings can also be taken in late spring or early summer and rooted in moist soil or water.

Comfrey is a vigorous grower and rarely needs repotting. If container-grown, repot every 2-3 years in early spring into a larger container with fresh, good-quality potting compost.
