black spot in Chicago

black spot in Chicago

Every year my roses get black spot. I've tried baking soda & water, commercial anti-fungals, removing all affected leaves, etc. Last year someone gave me a mini-rose that I planted in my back yard (the other roses are in the front) and it got black spot right away. Does anyone have any suggestions? I'd prefer not to use chemicals, especially ones that kill insects.
