Troubleshooting
Irene Nuss Cane Begonia problems — and how to fix them
Irene Nuss Cane Begonia (Begonia 'Irene Nuss') 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.
Leggy, floppy stems
Caused by insufficient light; move closer to a bright window. Prune woody older stems (2-3 years old) back to 4-5 nodes in early spring to encourage bushier regrowth.
Botrytis (grey mould)
Develops on dead flower petals and spent leaves in humid, poorly ventilated conditions; remove faded flowers promptly and ensure good air circulation.
Root rot
Overwatering in a pot without drainage is the primary cause; always use a draining container and tip out standing water from the saucer after 15 minutes.
