Caring for Lungwort

Lungwort is a low-maintenance perennial once established, but consistent moisture is key to success. Water regularly during dry spells, especially in spring and summer, to keep the soil evenly moist but not waterlogged. Plants in full shade or heavy clay soil need less frequent watering than those in brighter spots or free-draining loam. Reduce watering in autumn and winter when the plant is dormant and rainfall is typically adequate. Feed lungwort in March or April as new growth emerges. A light application of general-purpose granular fertiliser (such as blood, fish and bone) or a mulch of well-rotted compost or leaf mould provides sufficient nutrients for the season. Avoid high-nitrogen feeds, which promote soft, lush foliage more susceptible to mildew. Top up mulch annually in spring to suppress weeds, conserve moisture, and add organic matter as it breaks down. Powdery mildew is the most common problem, particularly in dry conditions or where air circulation is poor. It appears as white powdery patches on leaves from mid-summer onwards. Improve moisture levels and thin congested clumps every few years to increase airflow. Slugs and snails may nibble young leaves in spring; use organic pellets, barriers, or hand-picking if damage is severe. Lungwort is fully hardy and needs no winter protection. Clumps can be divided every three to four years in early spring or autumn if they become congested or to propagate new plants. Simply lift, tease apart, and replant divisions immediately, watering well.
