Anyone tried using Preen near/on Peonies?
I would like to use Preen near my peonies to keep weeds out of my garden. It's not listed on the label as an approved plant to use Preen on.
My peonies are along a hilltop in a row, with daylilies & phlox further down the hill. I figure if I put Preen 1.5 feet away from the peonies' centers it would be OK? Or has anyone tried putting preen directly around peonies? The label says you can try it on plants not on their list & see what happens, but I don't want to risk it!
