That's my take on it too Joe!. . .I think I just have a sickly bush!
The roses aren't that close together, and their is plenty of air
circulation around them, because they are out in the open, not even up
against a fence.
This January, I'm yanking that one out, giving it a proper burial, and
I'm going to replace it. . .No looking back;-)
