IOW, rose black spot.

You are probably right -Can't imagine what else it could be though. since it is common to all 3 of my roses. Thanks very much. After looking at the Missouri link, it is most DEFINITELY BS.

Well Moses - those are what I got so I got to go with them. I put Neem oil on at the first evidence of growth in the spring. Didn't do it again so next year I will be more vigilant. Neem is a fungicide. Should help some if you stay on schedule which I didn't. Thanks.

Neem can be tricky to apply. Foliage damage can occur if: applied too heavily, too strong a solution, too hot, or too sunny.

Moses

Thanks Moses. I have worked hard to avoid all of those scenarios. So far no leaf damage. Just BS.
