2 days ago I noticed that my Fern Peony was brown and in tough shape. Is it a fungus or possible reaction to chemical lawn sprays. below is a picture of what it produced this summer and a picture of what it looks like now.
2 years ago I noticed that I had a fungus on my regular peony bush and below is a picture of what it looks like again this year.
Would appreciate information on what I can do to save them.
