Creeping comfrey prefers consistently moist soil, especially when young and during dry periods. Water deeply when the top 2-3 cm of soil feels dry. Avoid waterlogging, as this can lead to root rot.

In very hot weather, more frequent watering may be necessary to maintain soil moisture.

Deadhead spent flowers to encourage further blooming and prevent self-seeding. Cut back the plant after flowering or in late autumn to maintain a tidy appearance.

Remove any dead or damaged foliage at any time of year to keep the plant healthy and visually appealing.

Creeping comfrey is easily propagated by division in early spring or autumn. Simply dig up established clumps and separate them into smaller sections, ensuring each section has roots and at least one bud.

Replant divisions immediately into well-prepared soil.

Symphytum grandiflorum is typically grown in borders and is not a plant that requires frequent repotting.

If grown in containers, repot every 2-3 years in spring into a slightly larger pot with fresh, well-draining potting mix. Ensure the new pot offers adequate space for root growth.
