Troubleshooting
Majeste Pulmonaria problems — and how to fix them
Majeste Pulmonaria (Pulmonaria 'Majeste') 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
The chief issue, especially in dry shade after flowering. Maintain soil moisture, shear tired leaves to regrow clean foliage, and improve airflow.
Faded or scorched silver leaves
Too much sun or dry soil dulls and burns the silver. Move to deeper shade and keep the root zone moist and mulched.
Wilting in heat or drought
Broad leaves flag quickly when dry. Water deeply and mulch; site away from competitive tree roots that strip moisture.
Slug and snail grazing
Emerging spring growth is vulnerable in damp shade. Protect young crowns with barriers or wildlife-friendly controls.
