Peony bulb/ weed killer

[Stacey]

I am new to the gardening scene. I absolutely love peonies so I got two bulbs. The bed I am placing them in has Bermuda grass trying to take over. After I weed my bed and do my very best to get as much out as possible, could I put Amaze weed preventer in the soil and then plant my bulbs?

I use an herbicide that is specific to grass. Except for a very few non-grass plants such as Potentilla (cinquefoil), it kills only grass. Brands include Poast and Grass Getter.
