Common spruce

Landscape Uses:Firewood, Screen, Specimen. Likes abundant moisture at the roots, if grown in drier areas it must be given a deep moist soil. Succeeds in most soils including those that are wet cold and shallow, but it is not very wind-firm in shallow soils. Intolerant of chalky or poor acid soils. Tolerates poor peaty soils. Prefers a pH between 4 to 6. Dislikes shade according to one report whilst another says that it is moderately shade tolerant. Intolerant of atmospheric pollution. Resists wind exposure to some degree and is tolerant of saline winds. A very cold-hardy tree when fully dormant, though the young shoots are subject to injury by late frosts, though less so than P. sitchensis. A fast growing tree, it is widely planted in cool temperate zones for its wood. Young trees often grow 1 metre or more a year and can sustain an average of 60cm for at least the first 60 years though growth tails off as they grow older. Probably not that long-lived in Britain, about 200 years seems the absolute maximum. In some upland areas, especially over granitic or other base-poor soils, growth rate and health have been seriously affected by aluminium poisoning induced by 'acid rain' pollution. There are many named varieties, almost all of them dwarf forms. A food plant for many caterpillars. A very aggressive tree, it is hostile to other trees. Susceptible to attacks by bark beetles so it should be kept away from more valuable trees. A biological control is being introduced (1983). This species is susceptible to honey fungus. Trees should be planted into their permanent positions when they are quite small, between 30 and 90cm. Larger trees will check badly and hardly put on any growth for several years. This also badly affects root development and wind resistance. Plants are strongly outbreeding, self-fertilized seed usually grows poorly. They hybridize freely with other members of this genus. The seed is shed in spring, the cones release their seed whilst they are still on the tree. The bruised leaves emit a delicious musky smell. Special Features: Not North American native, Inconspicuous flowers or blooms.

Edible Parts: Flowers Inner bark Seed Shoots Edible Uses: Tea Young male catkins - raw or cooked. Used as a flavouring. Immature female cones - cooked. The central portion, when roasted, is sweet and syrupy. Inner bark - dried, ground into a powder and used as a thickener in soups etc or added to cereals when making bread. An emergency food, used when all else fails. Seed - raw. Rich in oil and with a pleasant slightly resinous flavour, but too small and fiddly to be worthwhile unless you are desperate. A refreshing tea, rich in vitamin C, can be made from the young shoot tips. These tips are also used in making spruce beer. References More on Edible Uses

Seed - stratification will probably improve germination so sow fresh seed in the autumn in a cold frame if possible. Sow stored seed as early in the year as possible in a cold frame. A position in light shade is probably best. Seed should not be allowed to dry out and should be stored in a cool place. Prick out the seedlings into individual pots when they are large enough to handle and grow them on in the greenhouse or cold frame for their first winter. They can be planted out into their permanent positions in early summer of the following year, or be placed in an outdoor nursery bed for a year or so to increase in size. They might need protection from spring frosts. Cuttings of semi-ripe terminal shoots, 5 - 8cm long, August in a frame. Protect from frost. Forms roots in the spring. Cuttings of mature terminal shoots, 5 - 10cm long, September/October in a cold frame. Takes 12 months. Cuttings of soft to semi-ripe wood, early summer in a frame. Slow but sure.
