Troubleshooting
Begonia ferox problems — and how to fix them
Begonia ferox (Begonia ferox) 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.
Rhizome rot
Overwatering or heavy, soggy substrate rots the creeping rhizome. Use a free-draining mix, water at the base, and let the surface dry between waterings.
Low-humidity leaf browning
Edges crisp and texture flattens in dry air. Raise humidity with a terrarium or humidifier and keep it away from heat sources and draughts.
Powdery mildew
White powdery growth in still, humid air. Improve ventilation, avoid wetting the leaves, and remove affected foliage.
Leaf scorch
Bleached or browned patches from direct sun. Provide bright but filtered light and shield from harsh midday rays.
