Cedar of Lebanon trees (Cedrus libani) thrive in USDA plant hardiness zones 5 to 7. These slow-growing evergreens reach 40 to 60 feet tall and spread 30 to 50 feet wide, according to North Carolina State University. The dark green needles are flattened and the barrel-shaped cones are 3 to 5 inches long. Cedar of Lebanon trees grow in a natural pyramid shape while young. As these trees age, the top flattens and the shape spreads out wider. These conifers are commonly planted as permanent, long-lived showcase plants.
Remove weeds, grass and other debris from a 5-foot circular area. Choose a site with full sun exposure and plenty of room for the mature size of the cedar of Lebanon tree. Do not plant this tree under any overhead wires.
Dig a hole with a shovel that is twice as deep as the rootball and twice as wide. Break the soil up into pebble-sized pieces. Remove any rocks and sticks hiding in the soil.
Rough up the sides of the hole with the edge of the shovel. This helps to prevent soil compaction, which will trap the roots inside the hole.
Remove the cedar of Lebanon tree from its container. Turn the tree on its side and roll the container back and forth on the ground to loosen the rootball. Carefully tug the tree out of the container.
Loosen the roots with your fingers and spread them out. Place the cedar of Lebanon tree in the hole at the same depth that it was growing in the container. Adjust the depth by adding or removing soil from the hole.
Check to see if the tree is straight then fill the hole halfway with soil. Pour a couple of buckets full of water into the hole to help reduce the transplant stress. Fill the hole the rest of the way with soil. Do not firm the soil down since this can compact the soil.
