Troubleshooting
Begonia imperialis problems — and how to fix them
Begonia imperialis (Begonia imperialis) 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 and leaf spotting
Velvety leaves are prone to white powdery mildew and fungal spots in still, damp air. Improve air circulation, keep water off the foliage, and remove affected leaves.
Curling, browning edges
Low humidity is the usual cause for this terrarium-loving species. Increase ambient humidity with an enclosed case, humidifier, or pebble tray.
Rhizome rot
A buried rhizome or constantly wet soil leads to soft, blackened bases. Set the rhizome on the surface, use an open mix, and let the top of the soil dry slightly between waterings.
Leaf scorch
Bleached or crisped patches come from direct sun on the soft hairy leaves. Move to bright or moderate indirect light away from windowpane sun.
