Ripe fruits of keledang
 

               Keledang is more important as timber plant than as a fruit tree. The wood is heavy(density at 15% moisture content between 510-855 kg/m3) and is used for heavy construction, furniture, boat building, home appliances, coffins, and others. This plant also produces dyes.

Cultivation:

Keledang trees grow wild on soils ranging from sandy to clay.  These, however, seem to prefer a deep, well-drained soil.  Young plants need some shade, but need increasing light levels as they mature.

           New plants are raised from seed.  The seed should be sown immediately after extaction as they lose their viability within a week. There is no period of dormancy in seed and the germination is quite quick.
