Begonia 'Glowing Embers' problems — and how to fix them
Begonia 'Glowing Embers' (Begonia × hiemalis 'Glowing Embers') 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.
Crown and root rot
Collapsing, mushy stems from overwatering or soggy soil, the most common killer of Rieger begonias; keep soil only lightly moist and ensure sharp drainage.
Powdery mildew
White patches on leaves in humid, still air; improve airflow, avoid wetting foliage and remove affected leaves promptly.
Botrytis (grey mould)
Fuzzy grey rot on spent flowers and damp foliage; deadhead regularly, ventilate and keep leaves dry.
Decline after flowering
Plants often fade once the long bloom flush ends; they can be cut back to rest, but many gardeners treat them as short-lived flowering pot plants.
