What's eating my majeste pulmonaria?

Majeste Pulmonaria is an almost pest-free shade perennial but can develop powdery mildew in hot, dry summers, particularly if air circulation is poor. Slugs occasionally target the large silver-marked leaves in spring. Aphids are a minor nuisance. Cutting back after bloom and improving spacing prevent most issues.

Chalky white or grey powder on leaf surfaces from midsummer; leaves may yellow and shrivel in severe cases Cut foliage hard back in midsummer; water at soil level not overhead; treat with neem oil or a dilute bicarbonate of soda spray

Holes and scalloped edges on leaves, especially on new growth in spring; tell-tale slime trails Apply iron phosphate pellets; hand-pick after dark; use gritty mulch around crowns as a deterrent
