What's eating my sissinghurst white pulmonaria?

Sissinghurst White Pulmonaria is generally robust but susceptible to powdery mildew in dry summers, particularly once flowering ends. Slugs can damage the hairy white-flowered stems in early spring. Aphids occasionally cluster on new growth. Cutting back foliage after bloom and maintaining shade and moisture prevents most recurring problems.

Grey-white powdery film spreading over leaf surfaces in summer; affected leaves yellow and decline early Cut all foliage to the ground post-bloom to regenerate clean leaves; water at the root zone; spray with neem oil or potassium bicarbonate

Chewed holes in leaves and flowers in spring; silvery slime trails on and around the plant Hand-pick at dusk; beer traps; iron phosphate pellets around the crown; gravel mulch as a physical deterrent

Sticky, curled new growth; colonies of small soft-bodied insects visible on shoot tips and flower stems Jet of water to dislodge colonies; insecticidal soap or neem oil spray; natural predators (hoverflies, ladybirds) usually keep numbers low
