Torreya nucifera Cultivation | Propagation | General Uses Cultivation Notes: Succeeds in ordinary garden soil, tolerating some lime[1]. Prefers an acid soil[200]. Dislikes wind exposure[200]. Requires a sheltered position and either high humidity or a moist riverside soil[200]. Tolerates woodland shade very well[200]. Requires hot, very humid summers for best growth[200]. Trees are probably not hardy in all parts of Britain, but should succeed quite far north. A tree at Wakehurst Place was 11 metres tall in 1970[185]. A shrub growing in the shade of coniferous trees at Kew was about 2.5 metres tall and 4 metres wide in September 1993[K], it was carrying a very heavy crop of fruit[K]. No fruit was formed in 1994[K]. A specimen at Cambridge Botanic Gardens was 6 metres tall and 6 metres wide, it was carrying an enormous crop of seed in the late summer of 1996[K]. This plant has an excellent potential as a nut crop in Britain[K]. Sometimes cultivated for its edible seed in Japan, the variety 'Shibunashigaya' is considered to be the best for seed production[46]. The seed takes two summers to mature[229]. Plants are dioecious so both male and female plants are required if seed is to be produced. Occasional trees are monoecious with dioecious branches. Solitary trees have been seen on a number of occasions with heavy crops of fertile seed, so it would appear that the tree is not dioecious[K]. For further Torreya nucifera gardening information |
