Cultivation details
Industrial Crop: Fiber;  Management: Standard;  Regional Crop.

A plant of the tropical, humid lowlands[ 320 ]. It grows best in areas where annual daytime temperatures are within the range 28 - 42?c, though it can tolerate 5 - 49c[ 418 ]. It can resist occasional light frosts, with new growth being killed at -1?c, but dormant growth being tolerant down to -3c[ 418 , 598 ]. It prefers a mean annual rainfall of 750 - 4,000mm, tolerating 500 - 5,000mm and preferring a distinct dry season[ 418 ]. Grows best in a sunny position[ 307 ]. Prefers a deep, rich, well-drained soil, but tolerating a wide range of conditions[ 307 , 404 ]. Established plants are drought tolerant[ 307 ], and can also withstand occasional inundation of the soil[ 404 ]. Prefers a pH in the range 5.5 - 6.5, tolerating 4.9 - 7.2[ 418 ]. A fast-growing plant, especially when young[ 404 ]. The plant can commence flowering when around 8 - 10 years old from seed[ 404 ]. The plant produces suckers, especially when young, though they often die after 2 - 3 years, especially as the tree grows older[ 404 ]. Young trees can be coppiced, but older trees will often fail to grow back after being cut down[ 404 ]. The tree has a thick bark which acts as an insulation and allows it to recover from fires[ 404 , 598 ].
Propagation
Seed - sown fresh, without pre-treatment, they have a high germination rate[ 404 ]. Some reports suggest germination rates can be improved by pre-soaking the seeds for 12 hours prior to sowing[ 404 ], this is likely to refer to seeds that have dried somewhat[ K ]. Seeds can be sown in a sunny position, either in situ or in nursery beds. Sprouting takes place in 10 - 25 days[ 404 ]. Transplant 5cm tall seedlings to individual containers and plant out 12 months later[ 404 ]. Cuttings of half-ripe wood.
