Usages médicinaux

• Balsamic .

Autres usages

• An oleo-resin is obtained from the tree (probably from the trunk) [46, 61].
• It is balsamic and is used in medicines and in paints [46, 181].
• Wood - light, soft, not very durable .
• Used for pulp, construction, furniture etc [46, 181].

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].
• Requires a sheltered position, trees are susceptible to wind damage [11].
• Trees are tender in most parts of Britain[1, 11], they tolerate temperatures down to about -5 to -10°c [200].
• There are trees in Kent and Hampshire that are 12 metres tall [11].
• Grows best in the Perthshire valleys of Scotland and other areas with cool wet summers [11].
• Growth from young trees has proved to be very vigorous in Britain, 60cm in its first year has been recorded and 70 cm in its third year from seed [185].
• New growth takes place mainly between July and October [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].
• Plants are strongly outbreeding, self-fertilized seed usually grows poorly [200].
• Ils s'hybrident librement avec les autres membres du genre [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].
