Atlas Cedar (Cedrus atlantica): Care, characteristics, and complete guide

Introduction to Cedrus atlantica or Atlas Cedar

El Cedrus atlantic, also known as Atlas Cedar, is a spectacular evergreen conifer belonging to the family of Pinaceae. Native to the majestic Atlas Mountains in Morocco and Algeria, this tree has earned a privileged place in gardening and landscaping around the world thanks to its elegant bearing, its longevity and its resistance to both extreme cold and drought.

The Atlas Cedar stands out for its pyramidal crown when young, which evolves over time to acquire a more extended and majestic shape, with branches in well-defined layers. Its foliage, formed by intensely blue-green color —or blue-grey in the Glauca variety—, provides an unmistakable touch to gardens, parks and large open spaces.

Botanical characteristics of the Atlas Cedar

Cedrus atlantica is a tree of great size and longevity, capable of reaching heights exceeding 40 meters in optimal conditions. In its natural environment, it can even reach 50 meters. Its lifespan is truly remarkable, easily exceeding 500 years, and in some cases, specimens have been found to live up to a thousand years.

Throughout its evolution, the Atlas Cedar exhibits:

• Straight trunk with ashy bark in young specimens, becoming blackish brown, rough and with deep cracks in older specimens.
• Needles (needle-shaped leaves) up to 4 cm, persistent and grouped in a radial manner, reminiscent of a shaving brush, with tones ranging from light green to blue-gray.
• Cones or pine cones erect, large (5–10 cm long), cylindrical or dented in shape, maturing in about two years.
• Sexual differentiation in flowers: male flowers are greenish-yellow in color and female flowers are purplish-green or bluish in color, although they are not particularly ornamental.

The Atlas Cedar has several common names: blue cedar, silver cedar, Moroccan pine y Atlantic cedar, depending on the variety and region.

Ecology and natural habitat

The Atlas Cedar is endemic to the High Atlas Mountains, where it forms forests at altitudes between 1.000 and 2.800 meters. In these environments, it shares its habitat with other coniferous species and various fauna, such as the Barbary macaque, which finds refuge in its forests.

This tree shows a preference for:

• Deep, calcareous soils rich in organic matter, although its adaptability allows it to thrive in poorer substrates as long as they are not excessively humid or poorly drained.
• Climates with cold winters and dry summers, withstanding very low temperatures (up to -25 ºC) and even snowfall and strong winds.
• Dry environment: Its resistance to summer drought stands out compared to other conifers.

The distribution of Cedrus atlantica outside its natural habitat includes plantations in gardens, parks, and large estates around the world, as well as some wild enclaves in high mountain areas in different countries.

• Soils rich in organic matter promote more vigorous and rapid growth.

Irrigation

• Requires moderate wateringIt is very resistant to drought, although during the first years after planting Regular watering is recommended to encourage the development of the root system.
• Beware of excess water: the main enemy is the ponding.
• For mature trees, watering is only necessary during prolonged periods of drought or extreme heat.
• Watering should be deep and slow, ensuring that the water reaches the root zone.

Subscriber

• It does not require large amounts of fertilizer; just apply a nitrogen-rich mineral fertilizer at the beginning of spring.
• In very poor soils, a layer of compost or organic fertilizer can benefit young specimens.
• Mulch helps retain moisture and improve soil structure.

Pruning
