knock out roses
Several of my roses fell victim to the disease carried by mites. I ripped out the worst ones and then in February cut the others way back. They are now filled with leaves, but I have been told once they get it they will not come back. The owner of East Ridge Nursery said he had a product that will eliminate the disease, is there such a product or is there anything that can be done?
