last year, I had a few roses w/blackspot. Mainly the roses in the front yard along my sidewalk were it's really shady in the afternoon. So, Charisma & Intrigue got hit by it, along with Dolly Parton.... uh, can't really think. I know that Oranges & Lemons had it a little, as did George Burns. I just use GreenSpot Rose Spray once or twice & it's gone. Guess I'm lucky that way.
