My peonies and phlox are both suddenly looking bad. The peonies are wilting and the leaves on phlox are curling. For the first time in 30 years of gardening, I had my lawn fertilized and treated with weed killer last week. None of these plants are anywhere near the edge of the lawn, so I am wondering if this is a coincidence or not. Any ideas? And I will never get my lawn treated again!
