Troubleshooting
Winter Glow Bergenia problems — and how to fix them
Winter Glow Bergenia (Bergenia 'Winterglut') 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.
Winter leaf damage in wet climates
In mild, wet winters without hard frost, the red colouration may be less vivid and old leaves can become slimy. Remove damaged foliage in late winter/early spring before new growth emerges to maintain a tidy clump.
Vine weevil
Larvae feed on rhizomes from late summer, causing wilting. Adults produce characteristic leaf notching. Apply biological nematode controls in late summer. In containers, use loam-based compost and inspect rhizomes annually.
Slugs and snails
Despite the tough mature leaves, young spring foliage and flower stems are palatable to slugs. Apply iron phosphate pellets or use nematode drench in spring and autumn. Established plants sustain minor cosmetic damage without lasting harm.
