Cultivation Details

HabitEvergreen Tree
GrowthFast

A plant of the moist, lowland tropics, where it is found at elevations up to 800 metres[1]. It grows best in areas where the mean annual temperature ranges between 22 - 29°c, but can tolerate a range of 18 - 34°c[1]. It prefers a mean annual rainfall in the range 2,000 - 3,000mm, but tolerates 1,200 - 4,000mm, growing in areas with a distinct dry season and where there is no dry season[1]. Shade tolerant[1]. Prefers sandy soils in the wild[2, 3]. In the wild, it is found on rocky, shallow calcareous soils of mountain slopes and ridges, as well as on the deeper soils of the ravines and alluvial plains[1]. The plant develops a shallow root system, often suitable to mountain soils[1]. Prefers a pH in the range 6 - 8, tolerating 5.5 - 8.5[1]. A fast-growing tree[4].

Propagation

Seed - best sown as soon as it is ripe in a partially shaded position in a nursery seedbed or in individual containers. A moderate rate of germination can usually be expected, with the seed sprouting within 20 - 40 days[4]. When the seedbed-sown seedlings are 4 - 6cm tall, pot them up into individual containers and they should be ready to plant out 4 - 5 months later[4].
