Choose a location for your cedar where it will receive full sun. Avoid a location that is prone to flooding. Make sure the location is at least five feet away from other trees and brushes.
Water the area around the cedar tree thoroughly a few days before the transplant. Watering helps the tree weather the transplant and moist soil is easier to work with.
Using a shovel, dig a 20-inch deep trench around the base of the cedar. The diameter of the trench should be 2 feet wider than the diameter of the bottom tree branches.
Dig into the roots of the tree at a 45-degree angle, and cut off any taproot attached to the root ball. Rock the tree back and forth to loosen the roots from the surrounding soil. Once the roots are loosened, carefully drag the tree onto a tarp for transport.
Dig a hole to transplant the cedar into. Make sure the hold is at least two times the width and depth of the roots of the cedar. Don't leave the cedar out of the ground for more than an hour.
Transport the tree and tarp to the tree's new location. Position the tree into the hole, and fill the surrounding area with equal parts dirt, compost and peat moss.
Position the soil to create a 6-inch high moat around the base of the tree. This will ensure the roots receive adequate water. Water the cedar once a week with 2 to 3 gallons of water.
