Troubleshooting
Begonia carolineifolia problems — and how to fix them
Begonia carolineifolia (Begonia carolineifolia) 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
A buried rhizome or constantly wet soil leads to soft, blackened sections. Rest the rhizome on the surface, use a chunky mix, and let the top of the soil dry between waterings.
Powdery mildew
White powdery film on leaves in humid, stagnant air. Improve airflow, keep the foliage dry, and remove affected leaves promptly.
Brown leaf edges
Low humidity or fertiliser salt build-up on the large leaves. Raise ambient humidity, dilute feed, and flush the soil occasionally.
Leaf scorch
Bleached patches from direct sun on the big leaves. Move to bright indirect light away from harsh midday sun.
