Atlas Cedar Cedrus atlantica
ABOUT
The plant commonly known as the Atlas Cedar has a majestic appearance, characterized by its dense, pyramidal shape that can become more openly conical with age. The needles on this conifer are a stunning bluish-green to silvery-blue, adding a striking color to the landscape. These needles can be quite stiff and are typically arrayed in clusters on short side stems, giving the branches a somewhat tufted look. As a feature that makes this plant distinct, the bark is grayish with a rough texture, becoming deeply fissured with age. The cones, which develop on mature trees, are barrel-shaped, up to 6 inches long, and sit upright on the branches. They start off as green but mature to a brown color, standing out against the foliage. Overall, the Atlas Cedar presents a grandiose and elegant silhouette with its layered branches and eye-catching needle coloration, making it a favorite in many landscapes for its ornamental appeal.

WaterThe Atlas Cedar should be watered thoroughly but infrequently, allowing the topsoil to dry out between waterings. Generally, young trees require watering once a week, providing about ten gallons per watering to ensure moisture reaches deep roots. Mature trees are more drought-resistant and may need additional water only during prolonged dry spells, roughly once a month with twenty gallons. Adjust watering frequency with seasonal changes, reducing in the cooler, wet months, and increasing in hot, dry periods.
LightAtlas Cedar thrives in full sun, meaning it requires at least six hours of direct sunlight daily. It's best positioned in a spot in the garden or landscape where it can receive unfiltered sunlight throughout the day. Avoid planting it in shaded areas, as insufficient light can hinder its growth and health.
TemperatureAtlas Cedar is adapted to a wide range of temperatures, but it prefers a temperate climate. It can tolerate minimum temperatures down to about -20°F and can survive maximum temperatures typical of many temperate zones. The ideal temperature range for optimal growth is between 40°F and 70°F.
PruningPruning the Atlas Cedar is essential for maintaining its shape and health; it should be pruned in late winter or early spring before new growth starts. Prune sparingly, only to remove dead or damaged branches, and to correct any structural issues. Pruning every two to three years is usually sufficient unless the tree is damaged or growing too densely.
CleaningAs needed
SoilThe Atlas Cedar requires well-draining soil with a mixture of loam, sand, and compost to mimic its natural habitat. The best soil pH for this plant is slightly acidic to neutral, ranging between 6.0 and 7.5.
RepottingAtlas Cedar should be repotted infrequently, due to its growth rate; young trees may need repotting every 2 to 3 years, while mature trees can go longer without repotting.
Humidity & MistingAtlas Cedar prefers low to average humidity conditions, as it is adapted to the Mediterranean climate which is not overly humid.
Suitable locationsIndoor
Provide bright light, well-drained soil, and avoid high humidity.
Outdoor
Full sun, well-drained soil, protect from strong winds.

Life cycleCedrus atlantica, commonly known as the Atlas cedar, begins its life cycle as a seed, which after stratification germinates in spring, emerging as a seedling. The seedling grows into a juvenile plant and, over several years, develops into a young tree, characterized by rapid growth and the establishment of its root system. As it matures, the Atlas cedar experiences a slower growth rate and begins to produce cones after 20 to 40 years, with male and female cones borne on the same tree but in different clusters. Pollination occurs typically through wind dissemination, allowing the female cones to produce seeds. Once the seeds are mature, they are dispersed by the wind, birds, or other animals, falling to the ground where they can germinate to begin the cycle anew. The Atlas cedar has a long lifespan, often living for several hundred to over one thousand years, during which it may go through multiple reproductive cycles.
PropogationPropogation time
Spring to Summer
Propogation: Cedrus atlantica, commonly known as the Atlas Cedar, is typically propagated using seeds. The best time to sow the seeds is in autumn. Seeds should be collected from cones in late summer and then sown in a cold frame as soon as they are ripe to mimic their natural germination process, which follows after the cold period of winter. The seeds require exposure to cool temperatures, around 32 to 39 degrees Fahrenheit (0 to 4 degrees Celsius), for a stratification period which improves germination rates. Once sown, it may take one to two months or longer for the seeds to germinate. After the seedlings have emerged and grown strong enough, they can be transplanted to individual pots and eventually to their permanent location outdoors. This method preserves the genetic diversity of the species, although it is slow as it often takes several years for the tree to reach maturity.
