    I was talking with a new customer last week and he was showing me his peonies along the back of his property. He told me they come up healthy and bloom nice and then do this. It has been happening for several years. He had about a dozen of them and now may have half of that left.

    I'm assuming it's powdery mildew and trying to determine the best way to cure them

    They are generally cut back this time of year...and make sure to discard it.

    They have only dappled light in the pix and are up against a wall...

    Peonies suffer a number of issues w/out proper ventilation and light... I've never seen this type of thing kill plants,,, I'm guessing the location is doing that... or the planting depth,,, or the soil texture...

    I gotta say though,,, I've never seen it that bad before either... :)

    I hope you are pulling them out/cutting them off and throwing them away...

    Honeydew and sap falling from overhead trees feed the mold. Relocate them to more sun and out from under a tree canopy, and they'd probably fare better.
