Ensure that the new location will satisfy the needs of the plant. There should be a good amount of direct sunlight each day, and also good drainage of water.
Once the location has been selected, a hole must be dug for the plant. The hole should be large enough to house the entire root system freely, and not in a large clump.
Spread out the roots and add soil a little bit at a time and press firmly to remove any air pockets and reinforce the support for the plant.
The crown of the arborvitae, where the roots come together, should be just an inch or so beneath the surface of the soil, as the roots need air to grow.
Now, the plant must be watered gently, to ensure the roots are in contact with the soil.
Transplanting arborvitae is often done for a variety of reasons. One reason is that the plant may not be thriving in its current location. This may be for several reasons, including not enough sun or soil drainage.
Another reason for transplanting arborvitae is to create a better screen for wind or unattractive sights.
