Transplanting Trees and Shrubs Within the Landscape

This article was published originally on 3/25/1992
Occasionally the need arises to move existing trees or shrubs within the home landscape. Small plants may be moved by homeowners. Older, larger trees and shrubs should be left to professional nurserymen with the proper equipment.

The best time to transplant deciduous trees and shrubs is while they are dormant -- early spring before growth begins or in the fall after leaf drop. Evergreens are most successfully transplanted in April and late summer (late August to mid- September).

To reduce interference while digging, the branches of the trees and shrubs should be tied up with twine or small rope. Attach the twine to a low branch, then gently lift the branches upward and inward as the twine is wrapped around the plant. With the branches out of the way, it will be much easier to dig and move the plant without breaking limbs. It will also be safer for the individual, especially if the plant has thorns.

Most trees and shrubs are best moved with a ball of soil adhering to the roots. With many of the fine roots intact, transplanting shock should be minimized with faster reestablishment. The soil should be moist when the plant is dug. If the soil is dry, thoroughly water the area 2 or 3 days before digging the plant. The radius of the root ball should be approximately 8 to 12 inches for each inch of the trunk diameter at chest height. For shrubs, the radius of the root ball should be approximately 1/2 the distance from the dripline to the center of the shrub. Dig a trench with a spade around the plant to a depth of 1 1/2 to 2 feet. When digging the trench, work with the back of the spade toward the plant to prevent break up of the soil ball. Cut beneath the roots, rounding the bottom of the soil mass into a ball. Tip the soil ball to one side, slide a piece of burlap under the ball and secure the burlap tightly with twine or rope. Lift and carry the plant by the root ball rather than grasping the trunk. Do not allow the soil ball to break during the digging, moving, and transplanting process.

When transplanting trees and shrubs, it is not necessary to remove a large number of branches. Simply remove branches broken or severely damaged during transplanting.

Home gardeners should limit themselves to moving and transplanting small trees and shrubs. Trees with a trunk diameter greater than 2 or 3 inches should be left to the professionals.
