Thanks fellow gardeners for trying to help me out. Today I've attached two photos which I hope will be helpful in figuring out my dilemma. One photo shows the area where the hedge roses are planted. The bed is pie-shaped and wider in the back than the photo depicts. The second photo is a close up of these little orange spots that are interspersed with brown spots on the leaves. They feel somewhat raised from the surface of the leaf when I touch them.
I sincerely appreciate any help that is offered. Thanks for taking the time to help me out.
