Build a ring of soil around the planted tree to act as a water-catching moat. Proper tree transplanting is critical. Trees should be root-pruned the fall season before transplanting to encourage the growth of new feeder roots within the root ball. When you move the plant, dig a trench at least the width of the shovel around the tree and undercut the root ball, severing any large roots. Usually a large protective root ball of soil is lifted with the roots.
Professionals wrap the ball in degradable burlap and twine.
Trees can be transplanted with bare roots, but you must be careful not to let the roots dry out. Also, trim any damaged roots. The tree must be replanted at its original depth. Match your soil level by laying a stake across the hole. I apply a transplant fertilizer with nutrients formulated to encourage root growth.
