Select the new location from your plant. A new location should have full to partial sun for the holly to grow and thrive. Dig a new hole for the holly, twice the size of the root ball, but not any deeper.
Tie the bottom branches with twine to avoid any damage while digging and transplanting. Pruning the lower branches can also be done to gain easier access to the truck of the shrub.
Dig a trench along the outer edges of the shrub. With the shovel placed under the root ball, lift the shrub up and out of the hole with dirt intact around the roots.
Move the newly dug Japanese holly to the new location, centering the root ball in the hole. Back-fill with extra dirt, tapping gently around the plant to pack dirt, creating a watering well or trench around the holly.
Add new mulch to the inside of the watering well. Water the transplanted Japanese holly well.
