Troubleshooting
Begonia foliosa problems — and how to fix them
Begonia foliosa (Begonia foliosa) 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.
Leaf-edge browning
Dry air or inconsistent watering scorches the fine leaf margins. Raise humidity and keep the mix evenly moist.
Leggy, sparse growth
Too little light stretches the stems and thins the foliage. Move to brighter indirect light and pinch tips to encourage branching.
Root rot
Cold, soggy compost rots the fibrous roots. Let the surface dry slightly between waterings and ensure free drainage.
Powdery mildew
Grey-white film in stagnant, humid air. Increase airflow, avoid wetting foliage, and remove affected leaves.
