What to use to treat black spots on roses?

I have about 15 rose bushes and getting hit hard with black spots. I need something to stop this before it wipes all my beautiful roses out, what you recommend?


Bayer Advanced All In One Rose and Flower Care Granules are a very good option for black spot for roses. You will use 1 capful per plant. You will apply the granules to the base of the plant, work the granules into the soil and water thoroughly. You will reapply every 6 weeks and do no more than 3 applications per year. Make sure the roses and harborages are kept clean.
