Troubleshooting
Begonia 'Benitochiba' problems — and how to fix them
Begonia 'Benitochiba' (Begonia rex-cultorum 'Benitochiba') 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.
Brown, curling leaf edges
Low humidity is the classic rex complaint. Raise ambient humidity and keep watering steady to stop the margins crisping.
Powdery mildew
Rex begonias mildew easily in humid, stagnant air. Keep good airflow, avoid wetting foliage, and remove affected leaves at once.
Rhizome and root rot
Overwatering or a soggy mix rots the shallow rhizome. Let the surface dry between waterings and use an open, free-draining medium.
Faded leaf colour
Insufficient light dulls the silver and red. Move to bright indirect light without exposing leaves to direct sun.
