Great ideas from everyone, best of luck with your experimenting with potted trees. I am reluctant to try because of the extremely cold winters here and I have no garage. I will be potting peonies temporarily because my ground is frozen and roots arriving from Adelmans tomorrow. They will then be buried in the compost pile. From what I've seen of TP roots, they like to spread outward. It should be interesting to see how they perform. I have seen that in China it is a common practice as they will force them to bloom at different times of the year and have been successful for years.
