Troubleshooting
Begonia manicata problems — and how to fix them
Begonia manicata (Begonia manicata) 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 and root rot
Overwatering rots the thick rhizome, causing soft tissue and collapsing leaves. Use a free-draining mix, let the surface dry well between waterings, and cut away any soft sections.
Powdery mildew
White powdery patches appear in still, humid air. Improve airflow, keep the hairy foliage dry, remove affected leaves, and treat persistent cases with a fungicide.
Leaf scorch
Bleached or browned patches result from direct sun. Move to bright-indirect light to protect the large, glossy leaves and their red-fringed edges.
Failure to flower
Too little light or a too-warm, uneven winter can suppress the late-winter flower sprays. Give bright-indirect light and a slightly cooler, steady rest period to encourage blooming.
