Trim the Japanese boxwood’s foliage down to the main trunk section. Use clippers or hand pruners to remove thin branches. Prune away the entire canopy for easier digging and removal of the plant’s root system.
Prune off trunk sections and thicker branches of the Japanese boxwood. Cut through the larger branches and trunk using loppers. Trim the plant down as close to the ground as possible.
Insert a spade shovel into the ground 12 to 24 inches from the Japanese boxwood’s center. Dig down 12 to 18 inches to loosen and cut through the root ball. Step on the shovel with your foot and push down, to help cut through the roots.
Dig around the entire plant to cut through the root ball. Insert the shovel under the boxwood’s root ball and lift it from the planting site. Cut through any attached roots with loppers to release the plant from the soil, if required. Fill the empty hole with soil or replant with a healthy plant.
Clean the work area of clippings and plant debris. Rake up the Japanese boxwood cuttings. Place the cuttings inside a trash can, trash bag or onto a tarp and discard.
