What is the best treatment for black spot on roses?

I am just starting to see signs of black spot on several of my roses. I’ve never had this problem before, and I’m not sure why it’s cropping up all the sudden. What is the best treatment for this disease?

    First you must clean any debris from under the plants and put down new, clean mulch, then spray them with `qt h2o with 1tb baking soda disolved in it.

    First you need to minimize the cause. Black spot disease is caused by moisture. Thin the bush by removing some of the branches in the center at the ground or as close as you can get to the ground so more breeze can flow across the leaves. Then get some Funginex and use according to the directions once a week. When you water them don’t get the leaves wet and don’t water them in the evening.

    Normy is correct. Be sure you also pick off the spotted leaves and pick up any that have dropped to the ground.
