The Q&A Archives: peony bushes

Question: I have peony bushs that are next to a alley that has a lot of traffic.
This year with all the rain-I now have brown spots all over the leaves and stems. and they are getting worse. These have been very healthy bushs--I have had them in the same place for about 4 years.

Answer: Several fungi can cause leaf spots on peonies, especially after a wet spring. Soap Shield Fixed Copper (or any fixed copper fungicide) will help control the problem. Be sure to remove all foliage from the garden at the end of the growing season. Good luck with your peonies.
