Cultivation Details
A plant of the subtropics to the tropics. It is found in areas where the mean annual rainfall can vary from 800 - 3,000mm, with a distinctive dry season of several months. The mean temperature varies from 15 - 20°c in the cool season to 20 - 25°c in the hot season. Frosts are infrequent and light[1]. This species can tolerate occasional, short-lived temperatures down to around -8°c[2]. Plants are shade tolerant, at least when young, requiring more sun as they grow older[3, 4]. Prefers moist soil, growing best on alluvial and colluvial soils and poorly on eroded slopes and dry ridges[1]. The plant usually has a good rate of growth, averaging height increases of around 1 metre per year when young, gradually decreasing as the tree gets older. Bole diameter increase remains fairly constant at around 1cm a year. In a favourable site in Hawaii 36 year old trees were around 30 metres tall with a bole of 61cm diameter[1]. Root growth is shallow and vigorous; it can be destructive to pavements[4, 1]. Young trees generally coppice well[1].
