Water regularly, keeping the soil consistently moist but not waterlogged, especially during active growth and flowering. Reduce watering in winter when the plant is dormant.

Ensure good drainage to prevent root rot, as Spotted Bellflower dislikes sitting in soggy conditions.

Deadhead spent flowers regularly to encourage continuous blooming and prevent self-seeding. In late autumn or early spring, cut back the old foliage to the ground to promote fresh new growth.

Remove any dead or diseased stems as needed throughout the year.

Propagate by division of clumps in spring or autumn. Carefully separate the root ball into smaller sections, ensuring each piece has roots and shoots.

Alternatively, sow fresh seeds in autumn or spring in a cold frame or unheated greenhouse. Stem cuttings can also be taken in late spring.

Repot container-grown plants every 1-2 years in spring before new growth begins. Choose a pot one size larger than the current one, using a well-draining potting mix.

This helps to refresh the soil and provide more space for root development, preventing the plant from becoming root-bound.
