What Is Happening To My Peonies?

Question

My peonies didn’t bloom this year. They started to bud but then didn’t open. I didn’t notice ants on them like I have in the past but now some leaves are looking dusty and some look dead. They get watered daily so I know they aren’t dry.

Answer 1

It looks like they are being overwatered and they also have powdery mildew, a fungal disease. They could also have leaf blotch. This late in the year, I would cut back the foliage and reduce watering.
