Are you growing all of them in containers? It's no wonder, of course, because they would benefit from being moved into the shade on those very hot days.
I see you have Tom Brown, one of my all-time favorites. I also see you have William Morris, a rose I've always wanted. It has never been offered by any of my local nurseries, so I once ordered it from an on-line nursery and received Royal William instead. Royal William is a nice red hybrid tea, but it's a far cry from William Morris.
