Stained Glass Begonia problems — and how to fix them
Stained Glass Begonia (Begonia 'Stained Glass') 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.
Leaf spotting from water contact
Even clean water left on the thin, shiny leaf surface can cause permanent brown or pale spots; always water at the base and avoid placing where condensation or rain can splash the foliage.
Botrytis (grey mould) in cool, damp conditions
Cool temperatures combined with high humidity and poor air movement create ideal conditions for Botrytis cinerea; maintain temperatures above 18 °C, provide gentle air circulation, and promptly remove any dying leaves.
