Troubleshooting
Begonia 'Guy Savard' problems — and how to fix them
Begonia 'Guy Savard' (Begonia × 'Guy Savard') 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
Rex types mildew readily in still, humid air. Provide gentle airflow, keep foliage dry, and remove infected leaves.
Leaf-edge browning
Low humidity crisps the delicate margins. Grow in a humid spot or enclosure rather than misting.
Rhizome rot
Overwatering or a buried rhizome causes soft, blackened rot. Keep the rhizome on the surface and let the topsoil dry slightly.
Faded colour
Insufficient light mutes the silver-and-purple pattern. Move to brighter indirect light.
