Yeah, the recommendation that I've seen for any sort of fungus problem is to remove all of the surrounding leafy materials and to dispose of it (i.e. do not compost). One of my juvenile peonies got some funk from grass that was tossed on it during mowing. When I examined the gas, it had the same symptoms as my peony - and I am not sure how to handle that. Kinda makes me want to get a torch in late winter and to burn the dead grass just before spring.
