I removed infected leaves and stems. I can re-pot the ones that cleared up last year, but what else can I do to keep them clear and what can I do for the other bush? It is February, rainy, and the bush is starting to grow again, but already has black leaf this year. Thank you for the information, I try to keep on top of my roses. I sometimes over water if I forget. Anyway this was a big help, I went right out and cut the bad leaves and sprayed. Again, thank you.
I have heard that it is Dawn and baking soda and water, like 2 squirts of dawn, 2T baking soda, and then fill with water. Spray bottom and top of leaf. Repeat every week and after rain.
I would like a recipe for black spot on roses that is not a chemical, I think it has soda and something else that would be found in the kitchen. Also will skim milk really do the job?

Rake and remove all debris from around your plants before leaf bud each spring. As soon as you see plant leaf spots, treatment begins. For houseplants, isolate the pot immediately to prevent the fungus from spreading.
Remove any leaf that has been affected. Stop misting. For organic treatment, there are several safe and convenient treatments available. Most contain sulfur or copper octanate. For those gardeners who have no objection, many all-purpose fungicides are available. Please read the label carefully before applying.
