Begonia 'Midnight Magic' problems — and how to fix them
Begonia 'Midnight Magic' (Begonia rex-cultorum 'Midnight Magic') 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.
Crispy leaf edges
Low humidity or salt build-up. Raise humidity toward 50-60% and feed sparingly, flushing the soil occasionally.
Rhizome and crown rot
Soggy soil or a buried rhizome causes rot. Use airy mix, keep the rhizome at the surface, and let the soil dry between waterings.
Powdery mildew
A frequent rex begonia issue in humid, still air. Improve airflow and keep water off the leaves.
Winter leaf drop
Many rex begonias semi-rest in winter and shed leaves. Reduce water, keep warm, and growth resumes in spring.
