Tree Paeonies require sunny conditions and a well drained soil and may be left undisturbed. They prefer an alkaline soil, so please, add Dolomite or garden lime to your soil should it be too acidic. These plants also love old, well decayed, manures. During dormancy in winter the stem should not be pruned but left alone! Only on old Tree Paeonies where the shape of the plant has gone astray may careful pruning be considered. (See free growing notes.) Please order these before June!
