Rough-Leaf Begonia problems — and how to fix them
Rough-Leaf Begonia (Begonia muricata) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Fungal leaf spots
Water pooling in the rough leaf surface promotes Botrytis and bacterial spot; always water at the base and ensure good air circulation around the plant.
Root rot
Overwatering combined with a poorly draining mix causes roots to brown and collapse; lift and inspect roots if the plant wilts unexpectedly, trim rot, repot in fresh open compost.
