I think that you can go now if you want to. I will eventually have to start digging roots at the top of September because I want to be done by mid-October if possible. I have a bagged peony that has all but lost it's stems that I am thinking about planting now since it isn't going to benefit from sunlight at all.
Otherwise, early to mid-October. You want the peony roots to have some time to get established before the ground gets cold and they go dormant.
