, or in highly organic soils. It can grow in full shade, albeit slowly, through to full sun, given enough water. It is easily grown from fresh seed, germinating in a few weeks. Cuttings can be struck, although they tend to perform less well than seed grown plants. Cultivated specimens survive temperatures of 45 °C down to −7 °C; though it is known that trees growing in the mountains can withstand lower temperatures at least to −15 °C and no source provenance selection has been made for cultivation from there. Trees cultivated in western Scotland are stout and hardy.

Threats

Myrtle wilt, a parasitic fungus, attacks Myrtle beech when the air-borne spores settle on open wounds. It is a natural disease of N. cunninghamii, but in recent years it has become a serious problem due to poor logging practices.

Myrtle Beech forests can not survive strong fire, and must re-establish from neighbouring areas. They can, however, survive light fires, by regenerating from seed, or sometimes vegetatively from basal
