Moving Paeonies

Hi Nigel, if you're not in a hurry I would leave the Peonies until September or October. You could divide them then as well giving you some more clumps of a great plant. There is a myth that they, particularly, hate being moved. But my wife moved our Peonies around so much I remarked that they needed suitcases because of the times they were moved But no plant likes being moved whatever the time of year and will "sulk" until it recovers and Peonies are no different. It probably won't flower well for the first year but after that it will increase the flowering. One point, which I'm sure you're aware of, is to water the plant well during the first fortnight to ensure it doesn't get a set back due to lack of common sense care. Oh, and take a note of the present level of soil where they are planted and plant them again to the same level.
