Hi; I am looking for advice on powdery mildew on lilacs and on peonies. Can anyone help?
Have a read through this: Powdery Mildew on Lilac | Horticulture and Home Pest News
And this is general advice: Powdery mildew - Outdoors
Are the plants getting good air circulation? Are they being watered by sprinklers?
