Begonia 'Withlacoochee' problems — and how to fix them
Begonia 'Withlacoochee' (Begonia × 'Withlacoochee') 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.
Powdery mildew
Like most begonias it can develop white powdery patches in still, humid air. Improve airflow, keep leaves dry, and remove affected foliage.
Rhizome rot
Overwatering or a rhizome buried in wet soil causes soft rot. Keep the rhizome at the surface and let the mix dry slightly between waterings.
Brown leaf edges
Dry air or inconsistent watering crisps the leaf margins. Even out the watering rhythm and raise humidity modestly.
Stretched, sparse growth
Too little light makes leaf stalks elongate and the clump look thin. Move to brighter indirect light to keep growth compact.
