Begonia 'Silver Limbo' problems — and how to fix them
Begonia 'Silver Limbo' (Begonia 'Silver Limbo') 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.
Crispy leaf edges in dry air
This small Rex begonia is very humidity-sensitive. Grow it in a terrarium or use a humidifier or pebble tray and keep humidity around 50-70%.
Rhizome and root rot
Small pots stay wet easily, rotting the shallow rhizome. Use an airy mix, keep the rhizome at the surface, and let the top of the soil dry between waterings.
Powdery mildew
Stagnant, humid air in enclosures encourages mildew. Keep gentle airflow, water at the soil, avoid wetting leaves, and remove any affected foliage.
Faded silver / leggy growth
Too little light dulls the silver and stretches the compact habit. Move to brighter indirect light or supplement with a grow light.
