Main features: The cedar of Lebanon is an evergreen tree stately, up to 40 m high. Its branches towering pushing to the horizontal to give, after several tens of years, a port table very spread out. Become rare, it is often replaced by the cedar of the Atlas, which is very close.
The leaves (needles) are dark green, about 3.5 cm long are inserted spirally on the branches long and in small clusters (rosettes) on a short shoot.
The male inflorescences are born at the end of June as a small bud, rounded soft green in the middle of a rosette of needles. They mature in September and will release their pollen grains before they dry up and fall off.
The female inflorescence appears in late August and grows quickly until mid-September. First opened, its scales will close after pollination, in the fall. It then becomes a “conelet” well green that will grow steadily to reach 8 to 10 cm long, prior to désarticuler at the end of two or three years. Each shell would then release two seeds triangular, winged very developed.
Hardiness: Good resistance to cold up in the paris region.
difficulty Level: Easy.
Ground level: Siliceous tends acid, thin and stony, with a predilection for mountainous regions between 1000 and 2000 mr. heavy soils and clay does not suit him.
Exposure: Sun and light with a little humidity in the air. The cedars are mountain people able to withstand heat, crushing the summer and the snow in the winter.
Sowing/planting: The seeds should be planted at the opening of the cones, because they do not store in the open air. The cedars don’t respond well to transplants.
Conduct of culture: Its root system is very spread out and branched, the cedar of Lebanon needs a lot of space and light. It grows slowly, first in height and then spreads out as they age. It protects the soil from erosion.
Diseases and common parasites:
• Little attacked by the processionary moth.
• Some aphids, Cedeobium laportei and Cinara cedri attack the young branches and needles.
• A fungus, Phellinus chrysoloma can cause rot of the wood.
