Anbau & Pflege

Landscape Uses:Firewood, Hedge, Aggressive surface roots possible, Massing, Screen, Specimen, Woodland garden. An easily grown plant, it thrives best when growing in a deep well-drained soil in the western parts of Britain where it appreciates the higher rainfall. However, it succeeds in most soils and positions, being especially good on acidic sandy soils but also tolerating some lime so long as there is plenty of humus in the soil. Plants are very shade tolerant when young, but need more sunlight as they grow older. Plants are thin and poor when grown in dry or exposed places. A slow-growing but long-lived species in the wild, with specimens nearly 1000 years old recorded. It is occasionally planted as a timber tree in Germany. It is very slow growing in cultivation for the first few years, it then grows more rapidly with annual shoots up to 60cm long. This rate of growth soon slows as the tree loses apical dominance and it becomes slow growing again. Seed production commences around the age of 20 - 40 years, with good crops produced every 3 - 4 years. The crushed foliage has a sweet lemony scent. Another report says that it emits the unpleasant smell of hemlock. Many named forms have been selected for their ornamental value. Almost all of them are dwarf forms. Plants in this genus are notably resistant to honey fungus. Special Features:Attracts birds, North American native, Inconspicuous flowers or blooms.
Vermehrung: Seed - it germinates better if given a short cold stratification and so is best sown in a cold frame in autumn to late winter. It can also be sown in early spring, though it might not germinate until after the next winter. If there is sufficient seed, an outdoor sowing can be made in spring. Pot-grown seedlings are best potted up into individual pots once they are large enough to handle - grow them on in a cold frame and plant them out in early summer of the following year. Trees transplant well when they are up to 80cm tall, but they are best put in their final positions when they are about 30 - 45 cm or less tall, this is usually when they are about 5 - 8 years old. Larger trees will check badly and hardly put on any growth for several years. This also badly affects root development and wind resistance.

Edible Parts: Inner bark Shoots Edible Uses: Condiment Tea Inner bark - raw or cooked. Usually harvested in the spring, it can be dried, ground into a powder and then used as a thickening in soups etc or mixed with cereals when making bread. An emergency food, it is only used when all else fails. The leaves and twigs yield 'spruce oil', used commercially to flavour chewing gum, soft drinks, ice cream etc. A herbal tea is made from the young shoot tips. These tips are also an ingredient of 'spruce beer'.

Basketry Dye Hedge Hedge Resin Rust Tannin Wood Yields a resin similar to Abies balsamea, it is gathered by incisions in the trunk or by boiling the wood. A pitch (called hemlock pitch), is obtained by distillation of the young branches. 'Oil of Hemlock' is distilled from the young branches according to another report. The bark contains 8 - 14% tannin. The inner bark is used according to one report. The inner bark has been used in making baskets. A red to brown dye is obtained from the bark. A red dye is obtained from the inner bark according to another report. A little rock dust has been added to act as a mordant when boiling the bark. The boiled bark has been used to make a wash to clean rust off iron and steel, and to prevent further rusting. Tolerant of light trimming, plants can be grown as a hedge. This species does not make a good hedge in Britain. Some cultivars can be grown as a ground cover when planted about 1 metre apart each way. 'Pendula' is slow-growing but makes a very good cover. Wood - coarse-grained, light, soft, not strong, brittle, not durable outdoors. Difficult to work because it splits easily. The wood weighs 26lb per cubic foot. The trees do not self-prune and so the wood contains numerous remarkably hard knots that can quickly dull the blade of an axe. A coarse lumber, it is used occasionally for the outside of buildings. It should be used with caution as a fuel for outdoor fires because it can project embers and burning wood several metres from the fire.
