Water
Water moderately when the top 2-3 cm of soil feels dry. Avoid waterlogging, as Knautia integrifolia prefers well-draining conditions. Reduce watering in winter when the plant is dormant to prevent root rot.
Ensure good drainage in pots.

Watering, pruning, propagation, and repotting details from plant data
Water moderately when the top 2-3 cm of soil feels dry. Avoid waterlogging, as Knautia integrifolia prefers well-draining conditions. Reduce watering in winter when the plant is dormant to prevent root rot.
Ensure good drainage in pots.
Deadhead spent flowers to encourage continuous blooming and maintain a tidy appearance. Prune back plants in late autumn or early spring to remove dead or weak stems and to shape the plant.
This also promotes vigorous new growth for the next season.
Propagate by seed sown in autumn or early spring, or by division of established clumps in spring. Seeds may require stratification.
Cuttings can also be taken in late spring or early summer, but are generally less successful than seed or division.
Repot young plants annually in spring into slightly larger containers to accommodate root growth. Mature plants can be left in their pots for several years, as they prefer to be slightly pot-bound.
Ensure the new pot has adequate drainage holes.
