Tsuga canadensis is a genus that includes some evergreen conifers originating in North America and Asia. They are fairly long-lived trees, which reach 10-20 meters, depending on the species; the stem is erect, and the crown is conical, generally dense and well developed. The bark of the Canadian fir is gray-green and with time tends to break into flakes, remaining deeply marked; the leaves are flattened needles, gathered in groups of two, dark green in color; they remain on the tree two years before falling and spiral along the twigs. The fruit of Tsuga canadensis is a small round or slightly oval pine cone, containing numerous seeds; it matures in about six months and then falls, or remains on the tree for a few years. This plant is often used for hedges or borders, especially in dwarf species; poorly tolerates salt and pollution.
As for the correct location of this type of plant, it is advisable to place the Tsuga canadensis in a sunny place; in areas with particularly hot climates it is best to shelter the plant in partial shade or in full shade.
Generally, the Canadian fir does not fear the cold, preferring temperate climates to very hot ones. The plants of this variety are planted indifferently in spring or autumn. Speaking of pruning, we recommend pruning in the spring. This type of tree can withstand even massive and vigorous pruning without problems without presenting particular problems.
