Anyone used Preen to Suppress Weeds Around Peonies?
In the literature I got from Adelman Peony Gardens, they said it was OK to use "Preem" around peonies. I assume that's a typo, and I've never used Preen around them because peonies are not listed on the approved plant list on the package. Has anyone used Preen around peonies without harming them? Sue
