Origine géographique

Asie orientale - Japon

Autres usages

• Wood - strong, elastic .
• Used for construction, boxes, utensils, spindles etc [61].

Culture

• Prefers a good moist but not water-logged soil [1].
• Pousse bien dans les sols très argileux .
• Plants are very shade tolerant, especially when young, but growth is slower in dense shade [81].
• Intolerant of atmospheric pollution [1].
• Prefers slightly acid conditions down to a pH of about 5 [200].
• Prefers growing on a north-facing slope [200].
• Not a long-lived tree, but it is relatively fast growing [11, 81].
• Trees can put on new growth of 75cm two years after planting out and grow at up to 1 metre a year for the first 20 years or so of their life [185].
• Growth rapidly tails off at this age, however, and trees often die quite soon afterwards [185].
• Trees are very hardy, but in the milder winters of Britain they are often excited into premature growth and are then susceptible to damage by late frosts [1].
• Trees grow best in the Perthshire valleys of Scotland [11].
• Female flowers are produced relatively early in the life of the tree, usually by the time it is 6 metres tall [185].
• Trees should be planted into their permanent positions when they are quite small, between 30 and 90cm in height .
• Les arbres trop âgés se porteront mal et ne se développeront pas pendant plusieurs années .
• Cela affecte aussi dramatiquement le dévelopement des racines et la résistance au vent [200].
• The flowers are produced in axils of the previous year's shoots [275].
• Plants are strongly outbreeding, self-fertilized seed usually grows poorly [200].
• Ils s'hybrident librement avec les autres membres du genre [200].
• This tree is sometimes recognised as a separate species, A. sikokiana .
• Nakai [11].
• This species is sometimes grown as a 'Christmas tree' [200].

Propagation

• Seed - sow early February in a greenhouse or outdoors in March [78].
• Germination is often poor, usually taking about 6 - 8 weeks [78].
• Stratification is said to produce a more even germination so it is probably best to sow the seed in a cold frame as soon as it is ripe in the autumn [80, 113].
• The seed remains viable for up to 5 years if it is well stored [113].
• When large enough to handle, prick the seedlings out into individual pots and grow them on for at least their first winter in pots .
• Plantez les à leurs positions définitives à la fin du printemps ou au début de l'été, après les dernières gelées .
• Alternatively, if you have sufficient seed, it is possible to sow in an outdoor seedbed .
• One report says that it is best to grow the seedlings on in the shade at a density of about 550 plants per square metre[78] whilst another report says that they are best grown on in a sunny position [80].
