Our fatsia plant started to develop brown spots on its leaves last late summer. I removed the affected leaves, cleaned up underneath and applied fungicide. This spring it's much worse. We had a hard winter for NC with many days in the teens, which I mention in case it is a factor. It is in a partial shade/sunny place. Should I apply more fungicide move it or both? Or does it seem like something completely different?
