I'm having problems with rust and mildew on my Zinnia elegans. My USDA Zone is 7a SE. I'm using landscape fabric for my ground cover with driptape as irrigation to prevent splash-back on the foliage and I'm allowing plenty of spacing between the plants. They are getting about 6 hours of direct sunlight a day. Can you please suggest some other options to prevent this? I prefer organic solutions.
