Begonia 'Cowardly Lion' problems — and how to fix them
Begonia 'Cowardly Lion' (Begonia × 'Cowardly Lion') 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.
Faded colour
Too little light dulls the chartreuse and bronze tones. Move to brighter indirect light to restore the warm colouring.
Rhizome rot
Overwatering or a buried rhizome causes soft, mushy rot. Keep the rhizome on the surface and let the mix dry between waterings.
Brown, scorched leaf edges
Dry air, direct sun, or erratic watering crisps the ruffled margins. Raise humidity, filter strong light, and water evenly.
Powdery mildew
Whitish film on the textured leaves in humid, still air. Improve airflow, avoid overhead watering, and remove affected foliage.
