I planted all of bare roots separately in the center of lawn around 3 ft apart, some of peonies in other beds are showing yellowing - probably iron deficiency, but I do not worry about them. Those rings, though...May be someone had them or dealt with the similar situation before.

Southern Peony blog mentions viruses and basically owner keeps the plants regardless...
