I have planted peoney bushes about 4 years ago. They were in my front yard and did not do very well. I felt that maybe they did not have enough sun. I planted flowering shrubs and transplanted my peoney bushes on the side of my house in full sun. I did this last fall. This spring the peony came up and have grown good all summer. They did not bloom this spring but I thought they would not because of the stress from transplanting them. They are nice and healthy now. Is there anything I can do now to help them bloom next spring?
