Transplanting trees

This is a small cherry tree that will be moving from a front yard in Edina to our backyard.  It's a frustrating process to try to free the "tree ball" from the tangle of roots that seems to be intertwined with roots from other trees in the yard.  We hope to free the tree this evening and make the move.  There are 4 more trees from the same yard to transplant after that, including another cherry and some limelight hydrangeas.
