I started a thread on the iris forum regarding my concerns regarding a new bed I prepared for planting bulbs, siberian iris and peony in. When I finished the bed, I spread Preen on the bed until I was ready to plant my new arrivals. The siberian Iris and some of the bulbs will be fine but need some advice on the peonies.
Is there any issue with having Preen on the garden bed and planting new peonies in that bed?
Thanks for any help you can provide.
