Troubleshooting
Begonia 'Braveheart' problems — and how to fix them
Begonia 'Braveheart' (Begonia rex-cultorum 'Braveheart') 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.
Powdery mildew
A white, dusty coating on leaves and stems in stagnant, humid air. Improve airflow, water at the soil rather than the foliage, avoid misting, and remove affected leaves promptly.
Crispy brown leaf edges
Usually low humidity or dry air from heating. Raise ambient humidity with a humidifier or pebble tray and keep the plant away from radiators and cold draughts.
Rhizome and stem rot
Mushy, blackened bases follow overwatering or a buried rhizome. Plant the rhizome at the surface, use an airy mix, and let the top of the soil dry between waterings.
Faded or stretched foliage
Weak markings and leggy petioles signal too little light. Move to a brighter spot with strong indirect light, but avoid harsh direct sun that scorches the patterned leaves.
