What's eating my trevi fountain pulmonaria?

Trevi Fountain Pulmonaria is a tough, largely trouble-free cultivar. Powdery mildew remains the most common issue, especially in dry, warm summers. Slugs may nibble the vivid blue-flowered stems in spring. Aphids are occasionally a problem. Consistent moisture and cutting plants back after bloom prevent most pest and disease issues.

Dusty white coating on leaves in midsummer; leaves may brown at margins and die back early Cut foliage back hard after blooming to force fresh, clean growth; avoid overhead watering; apply neem oil or potassium bicarbonate spray

Holes and ragged notches in leaves, particularly in spring; slime trails visible at night or after rain Iron phosphate pellets (pet-safe); beer traps; hand-pick at dusk; mulch pulled back from crown reduces hiding spots

Distorted, sticky growing tips; soft insects clustered on new flower stems and leaf undersides Dislodge with a strong jet of water; insecticidal soap spray; beneficial insects such as ladybirds will naturally reduce numbers
