Having no idea as to your soil I can only relate my experiences. The weeds I pull from among the peony shoots trying to get their roots if possible. You should be able to locate the width of the peony root by probing with your fingers. Beyond that point I would scratch into your soil about 3 inches of finished compost. I have never found commercial fertilizer to be needed. You may need to support your bloom stems. To be safe you could do that now. Al

Thanks Al. I pulled as much of the grass roots as I could...they're pretty thick. This property is a wetland with lots of clay but the peonies are in a couple of small raised beds(well, one clump is in just a mound of soil) that were probably filled with bagged potting soil. I'll just have to wait and see if they do in fact bloom as I have no idea how(deep)they were planted, or how long they've been there. Good that I don't need to worry about ferts. If they don't bloom, I'll dig them up and replant in the fall. I should be able to find supports of some type around here...we're cleaning up a lot of yard junk. I'll try to post a photo later. Thanks again.
