Troubleshooting
Begonia 'Cleopatra' problems — and how to fix them
Begonia 'Cleopatra' (Begonia 'Cleopatra') 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
White dusty coating in humid, stagnant conditions. Improve airflow, keep water off the leaves, and remove affected foliage to stop it spreading.
Rhizome rot from overwatering
Soft, blackening rhizomes when soil stays soggy. Let the surface dry between waterings and grow in a gritty, free-draining mix and shallow pot.
Faded leaf colour
The bronze-gold marbling reverts toward plain green in low light. Move to a brighter indirect position to restore the contrast.
Leaf drop after flowering
Some leaf loss is natural as winter blooms finish. Ease off water and feed, tidy spent stalks, and growth resumes as light increases.
