Troubleshooting
Begonia solananthera problems — and how to fix them
Begonia solananthera (Begonia solananthera) 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.
Thin, sparse trailing stems
Stretched, bare vines indicate too little light. Move to brighter indirect light and pinch tips to encourage branching and a fuller, more cascading habit.
Uneven basket drying
Hanging baskets can dry out fast, stressing the plant and dropping buds. Check moisture often and water before the mix fully dries; soak thoroughly when watering.
Powdery mildew
White powdery film in still, humid air. Improve airflow around the basket, keep foliage dry, remove affected leaves, and treat persistent cases with a fungicide.
Root rot
Yellowing and collapse from cold, soggy soil. Use an airy mix, ensure the basket drains, and let the surface dry between waterings, especially in winter.
