My peonies come up into beds of ice. I used to worry about it but it doesn't seem to faze them. If I can drain them a little I do, but mostly I just let nature do it's thing. As I add mulch and compost around the garden the peonies seem to be getting deeper in little dished out earth. I don't bring any of that up to the plant but leave about 12" around the same height from the original planting level.
