Sorry to hear that, Greg, but that's the best you can do. A good thing to do is a baking soda spray as soon as the leaves get up a couple of inches. 3 tablespoons per gallon of water, along with a little oil for a sticker. It doesn't hurt anything, and I think it helps quite a bit. Then if you do see you're getting leaf spot, go the purchased fungicide route, but it shouldn't be as bad.
Enjoy the flowers, and look past the leaves. And hopefully it won't be as bad as you expect.
