Annette, I did put Alice Harding TP from Adelman in a grow bag and then into a plastic pot. I have it on a plant dolly and is currently sitting outside on my driveway against the wall for warmth and shelter. It has not been consistently cold enough for me to wheel it inside my garage. But I am dealing with only one tree whereas you have many to handle and care for. The digging and planting them in pots and bags must be a lot of work. I don't know how you do it. Can I ask you how did you go about digging up your tree peonies? Did you rent a tractor or tool to dig them up?
