I move trees bare root every fall until the ground freezes and most species take it fine. Mulberries often suffer some die back, though. When I started doing this my nursery was in a Z5 and we had lots of very cold winters, even a test one where it got well below -20.

I may have lost two tiny "sleeping eye" grafted peaches this winter, though. I stuck them in my vegetable garden and forgot to mulch them (they were an unexpected gift). The freeze- thaw pitched them out of the cracked soil. One of them was still mostly in the ground, so I'm hopeful.

I planted an angel red and a Russian pomegranite if the fall. They did not make it through the winter in Northern Virginia. I planted an apache blackberry bush and it also looks dead. Alternatively, I overwintered a natchez blackberry in a pot in an unheated shed and just transplanted it to its permenent location and it appears okay.
