Huh.. Only thing my roses are showing is being fried from the intense heat. I *really* want to deadhead & trim everyone up now that the extreme heat's past, but I can't because that'll encourage everyone to put out new growth and with my weather cooling off so fast, I'd be afraid of killing them w/a cold snap if they're putting their energy into growing rather than settling down for the winter.
What does powdery mildew look like? I have a rose that has had a whitish sheen to it all year.. Charles de Mills.
