Smooth Cane Begonia problems — and how to fix them
Smooth Cane Begonia (Begonia glabra) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Stem rot at the base
The succulent stems are vulnerable to rot if the compost remains wet for extended periods; ensure pots have ample drainage holes and allow compost to dry slightly between waterings.
Spider mites
Low humidity encourages spider mites, which colonise stem joints and leaf undersides; raise humidity and treat with neem oil or insecticidal soap at the first sign of fine webbing.
