Answer: The very best time to dig and transplant a rose bush is while it's dormant (late winter). Digging it while it's dormant will lessen transplant shock and will not interrupt the growing and blooming cycles. Or, you can wait until very early spring, just as the buds begin to swell on the canes to prune and then dig your rose bush. Transplant it into a container large enough to accommodate the roots without cramping. It can live in a container for several months providing you water and feed it regularly. Transplant it into its new home in late winter and by the following spring it should be ready to put out new growth.
Best wishes with your move!
