True cedars (​Cedrus​ spp.) are native to the western Himalayas, the Middle East and the Mediterranean. When adding a new tree to your landscape, the best time to transplant cedar trees is in fall, late winter and early spring when most deciduous trees are still dormant. Hardy in U.S. Department of Agriculture plant hardiness zones 5 through 10 depending on the species, there are only four true cedars. Carefully consider where to plant a cedar because they grow into large trees and can overwhelm a small landscape.

True Cedars and More

The true cedar species are the Atlas cedar (​Cedrus atlantica​), Cyprus cedar (​Cedrus​ ​brevifolia​ or ​Cedrus libani var. brevifolia​) and Lebanon cedar (​Cedrus libani​), hardy in USDA zones 6 through 9, and the deodar cedar (​Cedrus deodara​), which is also known as the Himalayan cedar, hardy in USDA zones 7 through 8. Under ideal conditions, the true cedars grow to 100 feet or more.

In the average North American landscape, while still very tall trees, cedars tend to grow 40 to 50 feet tall. There are smaller cultivars available, including the weeping deodar cedar (​Cedrus deodara​ var​. Pendula​), which only grows about 10 feet tall when staked and trained upward, making it an attractive focal point in a small landscape.

There are a number of North American native trees also known as "cedars," which are actually members of the juniper and cypress families. Familiar names among the other cedars are the Eastern red cedar (​Juniperus virginiana​), which thrives in USDA zones 2 through 9, and the Western red cedar (​Thuja plicata​), hardy in USDA zones 5 through 7.

Identifying a True Cedar

A quick way to determine whether the potted cedar tree in the garden center is a true cedar or other cedar species is to look at the needles. The true cedars produce 3/4- to 2-inch-long stiff needles that grow in spiral clusters, or rosettes. The other cedars have shorter, prickly needles when young, which become softer, thicker and flattened and have a scalelike appearance as the trees mature. In addition, true cedars produce barrel-shaped cones that grow upward from the branches.

Best Time to Transplant Cedars

Cedar trees, like other tree species, are best transplanted in early fall, late winter or early spring. While potted trees can technically be planted at any time of the year, planting during the hottest part of summer requires careful monitoring of the soil using a soil moisture meter so the tree doesn't wilt and die. Young cedar trees prefer an evenly moist soil, though mature trees can tolerate some drought.

Select a sunny, well-drained location in the garden where the cedar tree will have room to grow. Avoid planting near power lines, hardscape or buildings; while the true cedars grow at a slow to moderate rate, they mature into very large trees. Cedars prefer acidic, loamy soils, though they tolerate sandy and clay soils. Dig a planting hole half as deep as the root ball and two to three times as wide. Chop into the sides and bottom of the hole with a shovel to loosen the surrounding soil.

Settle the tree into the center of the hole at the same level as it was previously planted and backfill with the excavated soil. Tamp gently and water thoroughly. Cover the bare soil around the tree with 2 to 4 inches of organic mulch, pulling it back 6 inches from the trunk. Water the newly planted tree weekly when the soil is dry to a depth of 2 to 4 inches. Wait until early spring to fertilize and then apply a 10-10-10 slow-release fertilizer with micronutrients.
