Keep the soil consistently moist but not waterlogged. Water thoroughly when the top inch of soil feels dry. Reduce watering in winter when the plant is dormant.

Ensure good drainage to prevent root rot, especially in containers.

Deadhead spent flowers to encourage more blooms and maintain a tidy appearance. Cut back any dead or damaged foliage in late autumn or early spring. This helps promote healthy new growth and prevents disease.

Pulmonaria angustifolia is easily propagated by division of established clumps in early spring or autumn. Simply lift the plant, divide the root ball into smaller sections, and replant immediately.

You can also grow from seed sown in autumn.

Young plants may need repotting every 1-2 years into slightly larger containers. Established plants in the ground rarely need repotting.

If grown in a pot, repot when the plant becomes root-bound, typically every 2-3 years, preferably in spring.
