Troubleshooting
Diana Clare Pulmonaria problems — and how to fix them
Diana Clare Pulmonaria (Pulmonaria 'Diana Clare') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Powdery mildew
Less prone than older lungworts but still possible in dry shade. Keep soil moist, shear tired foliage, and improve airflow to limit it.
Scorched or dulled silver leaves
Too much sun or dry roots burns and fades the foliage. Relocate to deeper shade and keep the root zone moist and mulched.
Wilting in drought
Long leaves flag quickly when dry. Water deeply and mulch; avoid planting where tree roots strip soil moisture.
Slug and snail damage
Soft spring growth is grazed in damp shade. Protect emerging crowns with barriers or wildlife-safe slug controls.
