Q.Powdery mildew on peonies

Zone Windsor Ontario N8S2T6 | yvwilf2 added on July 18, 2017 | Answered

Is mid July to late to spray. Most of the leaves are half covered already. I tried earlier in early June with no results.
Also, what should I do this fall when I cut them back.

You can treat the plants every 10 to 14 days through the summer months.
