Troubleshooting
Glossy Abelia problems — and how to fix them
Glossy Abelia (Abelia × grandiflora) 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 dieback in zone 6
In the colder end of its range, stems may die back to the ground in harsh winters; mulch roots deeply in autumn and site in a sheltered, south-facing position — the plant typically re-sprouts vigorously from the root crown in spring.
Powdery mildew
White, powdery coating on leaves can appear in warm, humid conditions with poor air circulation; prune to open up the shrub and treat with a sulphur or potassium bicarbonate spray if persistent.
Anthracnose leaf spot
Irregular brown leaf spots caused by Colletotrichum spp. appear during wet summers; improve drainage and air circulation and remove affected foliage promptly to reduce spore load.
