Begonia 'Fedor' problems — and how to fix them
Begonia 'Fedor' (Begonia rex-cultorum 'Fedor') 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 powder on leaves in stagnant, humid air. Increase airflow, keep foliage dry and remove affected leaves quickly.
Leaf scorch
Bleached or browned patches from direct sun. Move to bright but filtered light.
Brown leaf edges
Low humidity or inconsistent watering. Raise humidity and keep the mix evenly moist.
Root and rhizome rot
Overwatering or heavy soil rots the base. Switch to a free-draining mix and let the surface dry between waterings.
