Yeah, agree with Liz. If one always amends their soil after digging and dividing I see no reason why one wouldn't be able to plant again in the same spot, except if the peony you just removed from that spot was diseased in anyway or had been there for 20+ years. Now, regarding the two no shows, it is still quite early in MN so they might not have popped as of yet. I still don't have all mine up. I had two in question so I dug down (very gently) to see if they had eyes that hadn't popped yet or if the peony was indeed toast. In one case the eyes just hadn't popped; in the other the peony was toast. Meh, live or die it's their choice, they can always be replaced.
Let us know what you do.
