Gave a start to a cork bark Chinese elm today that was just a root cutting last year. The older I get the more I enjoy working on young trees it just feels satisfying to start something that I know will only get better with time. It is also quick and easy.
Yes it was done last year after repotting a large cork bark Chinese elm that was growing in a 3 gal. container for many years.
I always look for interesting roots for cuttings when repotting Elms
