How to Transplant Old Boxwood Hedges

Cut the roots of the hedge with your shovel. Flip the shovel so that the bottom of the blade faces the hedge. Press the shovel into the soil in a circle around the hedge following the widest circumference of the foliage. According to Clemson University Extension this is called "root pruning." You should cut through the roots and leave the plant for four to six months, repeating the root pruning each month following the same circle, Clemson advises. Repeat for every boxwood you plan to move.

Cut baling twine into pieces 4 inches long and tie it to the foliage on the north side of each plant. This will help you orient the plant properly when it is placed in its new location, according to Clemson. Wrap additional twine around the shrub starting at the bottom and working your way up in a corkscrew fashion. According to Southern Living magazine online, this will compress the foliage and branches to protect them while you work. Be careful not to break the branches when pulling them up.

Dig a trench around the hedgerow, from the root pruning line away from each plant 12 inches wide and 24 inches deep. Slide your shovel blade under each boxwood in your trench to lift it up and out of the ground. Lift the plants along with the soil covered root balls and place it onto a plastic tarp. You should be able to slide each boxwood over to its new location, according to Southern Living.

Dig new holes for your boxwoods. Make each hole 24 inches wider than the existing root ball and 3 inches more shallow than the height of the root ball. Lift the shrub off of the burlap and place it into the hole. Twist the boxwood so your small piece of twine faces north. Fill the hole with the soil that was removed during excavation. Cover the soil beneath the shrub with mulch leaving a 3-inch gap between the trunk of the boxwood and the mulch. Repeat for each shrub in your hedgerow.

Place the leftover soil from the new hole and place it onto the burlap. Fill in the original hole with the soil from the new hole. Cover the soil with mulch. Water your hedge liberally and cut the twine to release the foliage. Water the hedge daily for four weeks to help the plants survive the shock of the move.
