Devil's-bit Scabious problems — and how to fix them
Devil's-bit Scabious (Succisa pratensis) 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.
Drought stress and leaf scorch
The plant rapidly wilts and foliage scorches if soil dries out in summer; a deep organic mulch and a cool, semi-shaded position help maintain adequate moisture.
Slugs and snails
Basal rosettes are vulnerable to slug damage in spring; use copper rings, biological nematodes, or hand-pick in damp evenings.
Powdery mildew
Can affect foliage in warm, dry spells despite this plant's preference for moisture; improve soil hydration and avoid overhead watering at night.
