Dragon-Shield Begonia problems — and how to fix them
Dragon-Shield Begonia (Begonia dracopelta) 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 crown rot
Water sitting on or near the creeping rhizome quickly leads to soft, brown, mushy rot; always water at the pot edge, ensure pots have drainage holes, and never leave standing water in saucers.
Leaf spot (Xanthomonas / fungal)
Water on the ornamental foliage combined with warm temperatures causes dark, water-soaked spots; water from below where possible and remove any affected leaves at the base.
