Maze-Leaf Begonia problems — and how to fix them
Maze-Leaf Begonia (Begonia daedalea) 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.
Rhizome rot
The creeping rhizome is highly susceptible to rot when soil stays wet; yellowing leaves that collapse at the base indicate rot — remove affected sections with a sterile blade and allow cut surfaces to callous before replanting in fresh dry mix.
Mealy bugs
Mealy bugs shelter in the crevices where the rhizome meets the soil; inspect regularly and treat with isopropyl alcohol on a cotton bud for isolated infestations, or a systemic insecticide for heavier infestations.
