A mature wisteria vine produces springtime blooms of pink, white or light purple. Transplanting wisteria can be challenging, especially when the plant is well established, with a trunk several inches in diameter. Expect a transplanted wisteria to take several years to re-establish itself and bloom. Transplant in late fall to early spring while the wisteria is dormant and when the soil is not frozen.
Cut the vine back to about 3 feet above ground.
Dig a circle about 18 inches around the wisteria’s main trunk. The root system will be extensive, expanding downward and horizontally. If your shovel is hitting roots, move further away from the trunk.
Continue digging around the rootball and then pry it upward. Try to get as much of the root system as you can. The more roots that are included, the better the wisteria's chance for survival at its new location.
Work the rootball onto the tarp and tie it closed. Transport the rootball to a sunny, well-drained location.
Dig the new hole twice as wide and deep as the rootball to allow the roots to easily expand. Up to 50 percent organic material, like compost or leaf mold, can be mixed in with the removed soil. Backfill the hole so the rootball will sit at the same level it had been in the ground. Set the rootball gently in the hole; the crown, where the root meets the trunk, should be at ground level.
Continue to backfill the hole halfway and then water well to compress the soil and remove air pockets. Finish backfilling the hole.
