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].
- This species is closely related to A. delavayi [11].
- A slow growing tree, but it succeeds in all parts of Britain [185].
- It grows best in the Perthshire valleys of Scotland [11].
- Very cold tolerant, but it can be excited into premature growth in the mild winters of Britain and this young growth is susceptible to damage by late frosts [1].
- 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].
- Plants are strongly outbreeding, self-fertilized seed usually grows poorly [200].
- Ils s'hybrident librement avec les autres membres du genre [200].
- This species is said to be found at the highest altitude of any tree in the world [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].
