how to get rid of brown spots on roses
My roses had brown spots on the leaves. Next day - no leaves. Now no roses. What can I do to bring them back? Thanks!

It sounds like you are having major fungus attack issues. I recommend going to a site called http://www.rosemania.com and purchase a product called mancozeb. Spray the roses with this product every 7 to 10 days for a month, they should leaf out and come back. The spray does leave a yellowish powdery residue on the canes and any new foliage, but that is part of how it works. Once the foliage comes back, spray the roses with a fungicide such as Green Cure fungicide every two weeks or less often if not real humid in your area. https://www.gardeningknowhow.com/ornamental/flowers/roses/
