Japanese Painted Fern with rusty brown leaves
Georgia, United States
I have Japanese Painted fern which is turning a rusty brown on some of the leaves. What is it and how do I treat it? It is planted in an area that gets some morning sun up until about noon. I thought maybe it was getting too much sun and had considered transplanting to a shadier area. I don't think it is spores. It is not powdery. The leaves that are affected are no longer green but look dry like they might be burned. Any other suggestions?
