Troubleshooting
Begonia pustulata problems — and how to fix them
Begonia pustulata (Begonia pustulata) 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
The textured leaves are prone to white mildew and fungal spots in still, damp air. Improve circulation, keep water off the foliage, and remove affected leaves.
Curling, browning leaves
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 rots the shallow base. 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 from direct sun on the soft leaves. Move to moderate or bright indirect light away from windowpane sun.
