Sequoia

Sequoia is a genus of evergreen coniferous trees that includes the single species Sequoia sempervirens. The genus Sequoiadendron also consists of a single species - Sequoiadendron giganteum. In the conditions of natural growth, these crops acquire truly gigantic dimensions both in height (California redwood grows up to 100 m or more in height) and in trunk diameter (there are specimens of giant redwood dendron, in which it exceeds 24 m in girth). In Europe, these trees can grow up to 15-20 m in height. Flowers and fruits of both species have no decorative value. The slender trunk of the evergreen sequoia can reach a height of 110 m and a diameter of 6-10 m. The crown is narrowly cone-shaped, the needles are flat, shiny dark green, 1.5-2 cm long. The bark of old trees is fibrous, red-brown, up to 70 cm thick. Wide at the base and tapering to the top, the trunk of giant Sequoiadendron is covered with light red bark. The crown is thick, conical or rounded, and the huge hanging branches resemble the tusks of a mammoth (hence the mammoth tree). The needles are hard grayish-green, about 6 mm long, arranged in a spiral pattern. The decorative form is 'Bluish' with green-blue foliage, 'Golden' - with young foliage of golden-yellow color, and a drooping form with second-order branches bent down. These plants are extremely resistant to diseases and pest attacks, which is evident from their age and size. These trees are long-lived, live up to 3-4 thousand years.

Cultivation

These outdoor crops are only suitable for large parks and gardens. Young plants are planted in a permanent final place in autumn (mainly in temperate climates) or in spring. They prefer deep and moist, well-drained soils, ranging from slightly acidic to neutral. During periods of drought, the soil around young specimens should be mulched with rotten foliage or peat to better retain moisture at the base of the plant. Pruning is reduced to removing dry branches or is carried out in such a way that the bark at the base of the plant is visible.

Location

Prefers a place in the open sun. Redwood evergreen may also be suitable for partial shade.

Temperature

These plants are resistant to both high and low air temperatures.

Watering

During periods of prolonged drought, it is recommended to water, although this applies only to young plants.

Reproduction

Redwoods are propagated by seed and growth (the only coniferous species), in culture also by cuttings. Sequoia evergreen forms offspring (lush erect branches growing from the roots of the plant), from which in September apical cuttings 10 cm long are cut and planted for root formation in a substrate of sand and peat. After root formation, they are treated in the same way as seedlings obtained from seeds. Sequoiadendron is propagated by seed, in culture-by cuttings and grafting.

Acquisition

These plants are not easy to get. Try your luck in gardening centers and specialized nurseries offering a wide range of crops. It makes sense to purchase these plants if you have a suitable soil for growing and a sufficiently large space at your disposal.
