Ideally, dig or rototill an area one foot deep and approximately five times the diameter of the root ball. The prepared soil will encourage root growth beyond the root ball and results in a healthier tree.
In transplanting, be sure to keep soil around the roots. Always handle your tree by the ball, not by the trunk or branches. Don't let the root ball dry out. Help prevent root girdling by vertically cutting any roots that show tendencies to circle the root ball. After placing the tree, pack soil firmly but not tightly around the root ball. Water the soil and place a protective three-foot circle of mulch around the tree.
