powdery mildew on flowers??
I have a problem with one of my Saintpaulias and hope you might be able to help. I have a plant which is quite healthy vegetatively but when it blooms the flowers, which are perfectly formed and of good color, develop patches of what looks like powdery mildew on them. Can you cast any light on this? Thanks, Cat
P.S. This "mildew" (or whatever it is) just began to show up this year. Before it was not present at all on this plant.
