Troubleshooting
Begonia pavonina problems — and how to fix them
Begonia pavonina (Begonia pavonina) 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.
Loss of blue iridescence
Caused by too much light. The structural colour only appears in dim conditions, so reduce light rather than increase it.
Crisping, browning leaves
Almost always low humidity or dry air. Grow in a sealed terrarium and keep humidity above 80%.
Sudden collapse or rot
From soggy substrate or stagnant air. Use a fast-draining mix and provide gentle ventilation.
Leaf-tip mineral burn
From hard tap water or fertiliser salts. Water with rain or distilled water and feed at low strength.
