Another powdery mildew victim

Powdery mildew — an ever present danger in Colorado gardens.

To battle it on a peony I am trying a top coat of a mouthwash solution.

Paeonia ‘Dr Alexander Fleming’

9/4/2016 powdery mildew. 30% solution mouthwash applied to leaves.  Trimmed lower leaves.

11/1/2016  Update

The mouthwash treatment kept mildew at bay for a couple weeks, but it was best to just cut the plant back to just above the ground.
