what can I do ii use copper spray according to directions
Erie County Ohio
Thank you for your question. It is difficult to diagnose your plants' problem(s) without having a photo of them, and to know what types of perennials they are. Copper spray is a dormant spray, but is useful for a limited range of problems. I suggest you take some pictures, and some leaves from the affected plants, and visit your county Extension office at 2900 Columbus Ave.,Sandusky (phone: 419-627-7631) to consult with a staff person there who can help you directly. Good luck!
