Growth—

A plant of low areas in the moist to wet tropics, where it is found at elevations between 150 - 1,000 metres[1]. It grows best in areas where the mean annual temperature falls between the range 22 - 28°c, though it can tolerate 10 - 32°c[1]. It can be killed by temperatures of 4°c or lower[1]. It prefers a mean annual rainfall of 2,800 - 3,500mm, but tolerates 2,000 - 4,000mm[1]. Older plants require a sunny position though they can tolerate shade in their early stages[1]. Prefers a fertile, acid, medium to heavy soil[1]. Prefers a pH in the range 4.5 - 5, tolerating 4 - 5.5[1]. The trees do not withstand fire[1]. It can be found in flat land as well as undulating and hilly ground.

Propagation

We have no specific information for this species - the information below is a general guide for the genus. Seed - best sown as soon as possible. It does not require pre-treatment, but it is recommended to soak the seed for 12 hours prior to sowing[2]. The seeds are sown in seedbeds, where they are covered with a mixture of sand and soil (1:1) or with a thin layer of sawdust[2]. Germination of fresh seeds is usually good and rapid. About two weeks after germination, when the seedlings are 5 - 6cm tall, they are potted up into individual containers about 15 x 23cm with good drainage holes at their base[2]. It is normally recommended to use a mixture of forest soil and sand (at a ratio of 3:1) as the potting medium in order to introduce the appropriate mycorrhiza to the roots. The seedlings are placed in 50 - 60% sunlight and watered twice daily[2]. Seedlings can be planted out when 30 - 40cm tall - harden the seedlings off in full sunlight for one month prior to planting[2].
