Cultivation Details:
Prefers a light sandy loam and a very sunny position sheltered from strong winds[1, 49, 89]. Succeeds in any good garden soil that is not excessively limey[11], it also succeeds in dry soils. Most species in this genus become chlorotic on limey soils[200].
This species is one of the hardiest members of the genus, it succeeds outdoors in the milder areas of the country, but even in Cornwall it can be killed back to the ground in excessively harsh winters[11]. It will, however, usually resprout from the base. Plants require hot, sunny summers if they are to ripen their wood fully and flower freely. In Britain they tend to do best when grown in coastal gardens in a sunny, sheltered position that is protected from the wind[11].
A very ornamental tree[1], it is closely related to A. dealbata[11].
The cultivar 'Mollis' is notably resistant to honey fungus[200].
This species has a symbiotic relationship with certain soil bacteria, these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby[200].

Propagation Notes:
Seed - best sown as soon as it is ripe in a sunny position in a warm greenhouse[1]. Stored seed should be scarified, pre-soaked for 12 hours in warm water and then sown in a warm greenhouse in March. Germinates in 3 - 4 weeks at 25°c[133].
Cuttings of half-ripe wood with a heel, July/August in individual pots in a frame[78]. Overwinter in a greenhouse for the first winter and plant out in their permanent positions in late spring or early summer. Fair percentage[78].
