Begonia convolvulacea problems — and how to fix them
Begonia convolvulacea (Begonia convolvulacea) 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.
Sparse, stretched vines
Long internodes and few leaves come from low light. Move to brighter indirect light and pinch tips to encourage denser, branching growth.
Crispy leaf edges
Browning margins from low humidity, this rainforest climber's most common complaint. Raise humidity well above 60% with a humidifier or enclosure.
Powdery mildew
White coating in humid, stagnant air. Keep humidity high but ensure steady airflow, remove affected leaves, and avoid wetting the foliage.
Root rot
Despite liking moisture it rots if waterlogged. Use a free-draining airy mix and a draining pot, and let the very top of the soil dry between waterings.
