What to do about mildew (mold?) on indoor begonia

Question

My beautiful begonia has been sitting above the kitchen sink since late May. I just discovered there are white to grey spots on many of the leaves. How can I treat it and keep it in the house? Or should I just dispose of it? It is still warm enough at night here (Colorado) that I can leave it outside right now, but did hope to keep the plant in the house during the winter.

Answer 1

You can spray the plant with Neem Oil.
Use it weekly until the problem clears up. Neem Oil is safe for people and pets.
