Growing Blue Atlas Cedar
Blue Atlas cedars need plenty of room to spread out. In the garden, the Blue Atlas cedar grows quickly in height to about 20 feed and then begins to spread out to upwards of 35 feed across, so siting the perfect location for this tree is critical.
Blue Atlas Cedar are very drought tolerant, however they grow very slow without adequate water during the initial establishment period. Staking young trees is recommended to minimize the stress on the stem from winds blowing the tree. When tying trees to stakes remember the tree will continue to grow. Loosely tie the tree with several twist ties to allow for growth. Check trees every three months and loosen as needed. If this is not done, the twist tie will grow into the tree causing injury. A Pro tip that I can offer is to use a short length of old garden hose and run the tie wire through the hose. this will protect the trunk of the tree from being damaged by the tie wire.
The one question that comes up often when talking to customers is “when is the best time to plant.”? For the most part, container trees can be planted year around, provided the ground isn’t frozen. Below Virginia many nurseries and Christmas tree growers field plant year around, weather permitting. When planting a potted tree, remember the only water source the tree has, is its small root ball, and all the water the tree uses must come from them until new roots can grow into the surrounding soil. New trees should be watered twice weekly (Minimum), under hot drier conditions possibly more. Care should be taken not to over water. More trees die from over watering than under.
Soil Types for Blue Atlas Cedar
Blue Atlas Cedar grows well in a wide range of soils, ranging from all sand to pure red clay . When planting in very sandy soils adding organic matter is always recommended to improve the soils ability to hold water and nutrients. When planting in hard clay soils, its best to dig the hole several feet wider than the root system and fill with soft loam soil to give the young Blue Atlas Cedar a faster, more aggressive root system.
Blue Atlas Cedar prefer well drained soils but will tolerate wet soils for short periods of time. Blue Atlas Cedar should never be planted in soils that are excessively wet for long periods of time. Since Blue Atlas Cedar have a shallow root system, weeds and grass growing around the tree will cause the tree to grow much slower until established. Mulching will improve your growth three fold. Mulch not only stops weeds and grass, it will hold soil moisture and maintain a lower more even soil temperature, stimulating more aggressive root growth.

Insect problems with Blue Atlas Cedar Trees
Blue Atlas Cedar only have a few insects that cause any real cause to worry. Bag-worms are probably the worst pest, on small trees Bag-worms can be picked by hand but larger trees need to be sprayed. Scale is another insect that attacks Cedars, they look like little crusty flakes covering the needles and branches. Scale feed on sap causing a chlorosis (yellow) look to the needles. The most difficult insect to control on Blue Atlas Cedar is Spider Mites. These are very small insects that can be seen with a magnifying glass. Feeding on the sap causes needles to turn yellow and later brown. Spidermites have become resistant to most of the old chemicals. We recommend using only true miticides for control.
History of Blue Atlas Cedar Trees
The Atlas Cedar (Cedrus atlantica) takes its name from the Atlas Mountains of Northern Africa from which it is native. In 1827 on a visit to Tangier, Morocco, English botanist P.B. Web discovered the Blue Atlas cedar. By 1840, Britain and Europe began to cultivate the tree which was later introduced to the United States.
Oil extracted from the Blue Atlas Cedar was used by ancient Egyptians for embalming, cosmetics, perfumery, incense and medicinal purposes. The natural aroma serves as an insect repellent, making the wood a popular choice for modern furniture builders.

Follow these guidelines for the best results
STEP 1: PLANTING
In general, the hole should be big enough to accommodate the size of the root ball. Some recommend a sloped-side hole about a foot deep and five times as wide as the root ball. The root collar should be above the level of the land. Place the tree in the hole. Aim for the center of the hole. Once inside the hole, the root ball should be above 1-1.5 inches (2.54-3.81 cm) above the ground on all sides, so there is a slight crown to allow for drainage and proper mulching. If the tree collar is lower than ground level when you place it in the hole, add some soil under the root bulb and re-situate the tree. Point the roots downward as best possible, and fill the remaining hole with the pile of dug up soil. Compact the soil very tightly around the roots, and remove any air pockets. Use good planting soil and fresh compost to guarantee the roots have plenty of nutrients
STEP 2: FERTILIZE
We recommend when planting your plants to use Bio-tone starter fertilizer by Espoma. We have trialed many so called “starter fertilizers” over the years and have come to rely on Bio-tone exclusively for our own use. Simply mix the recommended amount of Bio-tone into the back fill soil and water in generously when back filled. Bio-tone® Starter Plus is an all-natural plant food that is combined with a stronger concentration of beneficial bacteria along with both endo and ecto mycorrhizae. Basically the “good” fungus in Bio-tone colonizes on the growing roots of your newly planted plant and does not allow disease causing fungus to attack the new roots. It has also shown promise in stimulating the growth of the new roots which means quicker establishment for you plant. After establishment and during the following years we recommend Holly-tone used at the recommended rates. It is also organic and slow release which will feed your trees the proper amount of nutrients over a period of time rather than all at once which can burn the root tips and actually have the opposite effect of slowing down plant growth. It also will help to maintain the acid level in the soil that Blue Atlas Cedar Trees need to thrive.
STEP 3: WATER
Blue Atlas Cedar Trees have a shallow root system so they need to be watered often in the first year after being planted. If the soil is sandy or drains really quickly or if it’s been excessively hot out, you should check the soil around your tree to see if it’s getting enough water. The soil should be wet about 1 inch below the surface. To fix this issue, simply water your Blue Atlas Cedar more often and/or for longer periods of time. Once established, Blue Atlas Cedar Trees can tolerate periods of drought.
STEP 4: MULCH
Lay a 2- to 3-inch layer of organic mulch, such as pine needles, over the soil surrounding the cedar tree without pressing it against the trunk; mulch assists in deterring weeds, conserving moisture and lowering pH.
