Troubleshooting
Begonia 'Tiny Gem' problems — and how to fix them
Begonia 'Tiny Gem' (Begonia × 'Tiny Gem') 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.
Crown and rhizome rot
From water settling in the dense rosette or soggy soil. Water at the base and use a free-draining mix in a small pot.
Powdery mildew
White coating in still, humid conditions. Increase airflow and keep the foliage dry.
Leggy, loose rosette
Too little light. Move to brighter indirect light to keep growth compact.
Leaf-tip browning
From dry air or fertiliser salts. Raise humidity and feed at reduced strength.
