Tree paeonies should be planted at the depth they were in the pot in which they were bought. The only thing to avoid is letting them dry out at any time. Feeding is probably the way to get more flowers. They do like a good rich soil. Try Tomorite now and then a general purpose feed in early Autumn.

I bought 3 as bare root plants 2 years ago and put them in pots. Due to my ill health i was unable to give proper care. This year i am taking stock of the garden again. So will now start giving them the care they deserve. Thank you Owdboggy.

I have had a tree peony for a long time, mostly in a pot, stopped flowering, so transferred to the garden. I have the label filed. The back of the label says to plant the graft, if there is one, 2 inches below the soil. I would add that watering close to the peony stem may uncover the graft, so check that this has not occurred. The word mulch is mentioned on the label, so it is the opposite to a peony. You can mulch it, if you do that to a peony they sulk. Label also says sunny, open, well drained position. My tree peony has bloomed well after this transplant to the garden.

Thank you Doriac. Your advise is much appreciated.
