Troubleshooting
Begonia × erythrophylla problems — and how to fix them
Begonia × erythrophylla (Begonia × erythrophylla) 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.
Rhizome rot
Overwatering or a buried rhizome causes soft, mushy decay; keep the rhizome on the surface and let soil dry between waterings.
Powdery mildew
White powdery film on leaves in humid, poorly ventilated spots; improve airflow and keep foliage dry.
Leggy, sparse growth
Too little light stretches the stems and spaces the leaves; move to brighter indirect light.
Leaf scorch
Brown crisped patches from direct sun; relocate out of harsh light into filtered brightness.
