My roses have black edges on the petal of the flowers. I have used Bayer treatment - what else can I do? They are well established healthy plants with beautiful deep red blossoms

The black margins indicate a fungal disease. You may want to try using Rose Defense, a neem oil based fungicide/insecticide. It should help keep your roses insect and disease free.
