Troubleshooting
Escargot Rex Begonia problems — and how to fix them
Escargot Rex Begonia (Begonia rex-cultorum 'Escargot') 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
White powdery patches from stagnant air and wet leaves. Water at the soil, improve airflow, avoid misting, and remove affected leaves promptly.
Crispy leaf edges
Low humidity or underwatering. Raise ambient humidity with a pebble tray or humidifier and keep the soil evenly (not constantly) moist.
Rhizome and root rot
From overwatering or planting too deep. Use a shallow pot and airy mix, keep the rhizome at the surface, and let the top of the soil dry slightly between waterings.
Winter leaf drop / dormancy
Rex begonias often shed leaves and rest in winter. Cut back watering, keep them warm and bright, and growth resumes in spring.
