Would Milk Spray Treatment Help Peony Bushes With Black Spots
Question From: Westland, Michigan, United States
Q: Just read your column in Homestyle, 7/24/15 regarding milk as a spray for diseases. Can this be used on flowering plants? I have some black spots on a peony bush. Also would powdered milk be as effective? Thank you.
The milk remedy is targeted for powdery mildew. I would take a sample of your infected peony leaves to your local independent garden center for an accurate Id and recommendation for a control. Best Nancy
