Troubleshooting
Silver Light Bergenia problems — and how to fix them
Silver Light Bergenia (Bergenia 'Silberlicht') 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.
Vine weevil
Adults notch leaf margins; larvae destroy rhizomes from late summer onward. Apply biological nematode controls in late summer. Particularly problematic in containers — use loam-based compost with added grit and inspect roots annually.
Slugs and snails
Young spring growth and flower stems are targeted. Use iron phosphate pellets, copper barriers, or nematode drench, especially in shaded, moist positions. Established plants sustain some cosmetic damage without serious harm.
Leaf spot
Fungal spots appear as brown or tan blotches on older leaves, particularly in wet or humid seasons. Remove affected foliage promptly. Divide congested clumps to improve airflow and avoid overhead irrigation.
