I think with that much rain it would have been super hard to keep anything dry. Maybe next year you will have to buy them their own shelter from the rain! It's actually been a little dry here so far.

Mr. Reath is correct, it is botrytis. I saw the same symptoms when I was working at a retail nursery in 2003, four springs ago. It was my first spring here after relocating to upstate New York, and I remember how cool and rainy it was during April, May, and June of that year. It was sickening to watch large healthy plants melting away daily. The plants were unsaleable and had to be put in a holding area until end-of-season sales started. Spraying is the only option. The fungal spores are long-lived and always seem to be omnipresent in the environment. Your plants are well sited and have plenty of air circulation but the constant rains this summer have trumped your efforts. I liked your observation regarding the identification of fungus on plants – i.e. how the same fungus can vary its look on different plants. Yes, botrytis is usually fuzzy but not on peonies. As an FYI, powdery mildew classic symptoms are fuzzy white spots and patches on leaf surfaces, stems, and flowers, but not on hydrangea macrophylla types and hybrids. I used to work for a potted plant nursery that forced hydrangeas into early bloom for Valentine and Easter sales. Part of the growing regimen was a spray program to spray the undersides of the leaves to prevent the first outbreaks of pm. How disheartening, Kathy. Mr. Reath is correct, it is botrytis.
