Jerry, I seem to recall that you posted in another thread about roots pushing up and rising above soil . I am seeing this happening to some of my peonies that were planted in poorly prepared holes. I am piling soil on top of them to cover the roots as a temporary solution. Guess I will have to dig them up and move or prepare deeper planting holes for them.
Mary like you, I tried to plant them 3ft apart. In some cases, I put them closer because I ran out of space. As a result, I have to move 3 peonies this month because they are starting to crowd out their spaces and their neighbors. I am planning to dig up Buckeye Belle, Myrtle Gentry, and mislabel itoh from MB this week and plant them somewhere else. These did not bloom well for me last year. Is Garden Treasure very wide? Can I ask how short is your GT?
