Cultivation Details

HabitSemi-deciduous Tree
Growth—

A plant of the tropics, where it is found at elevations from 700 - 1,000 metres. It grows best in areas where annual daytime temperatures are within the range 27 - 35°c, but can tolerate 12 - 45°c[1]. When dormant, the plant can survive temperatures down to about 8°c, but young growth can be severely damaged at 10°c[1]. It prefers a mean annual rainfall in the range 1,000 - 1,500mm, but tolerates 770 - 2,000mm[1]. Often found on sandy soils in the wild[2]. Succeeds in a wide range of well-drained, fertile soils[1]. Prefers a pH in the range 5.5 - 6, tolerating 4.9 - 7.2[1]. A plant of lowland areas in the moist tropics[3]. A widespread tree, unusual within its genus for its adaptation to withstand adverse climatic conditions and soil types[2].

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[4]. 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[4]. 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[4]. 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[4]. Seedlings can be planted out when 30 - 40cm tall - harden the seedlings off in full sunlight for one month prior to planting[4].
