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.

Preen is supposed to be a preemergence herbicide and only works by preventing seeds from germinating. Many iris growers use it religiously so it should not harm peonies. I really need to get some for my iris and peonies.

I was being cautious since I didn't know what problems Preen could cause since it had been spread on top of the bed prior to any bare roots being planted in the soil. Also, I noticed on the website and container of Preen that it is not listed to be used with peony so that was my concern. I figured perhaps I could just scape the soil surface off with the Preen to avoid any negative effects.
