Hi everyone-- new member here. I bought my house last year and inherited with it some wonderful perennials, including a peony that bloomed prolifically this year. I added two new peony plants to the planting bed this spring, and all three were thriving. I returned home after a week of vacation and found one of the spring planted peonies looking like this-- see attached photo.
Any help? I have both agri fos and bonide infuse fungicides which I'd rather not use, but purchased to treat my Yoshino cherry trees earlier in the spring.
Thanks for any help!
