Tree Management

Propagated by seed, natural seedlings, and stem cuttings. Seeds may be collected in large quantities (1 kg contains 61,500-90,000 dry seeds) and stored for up to 6 month. Germination starts 1-3 weeks after sowing. 70% of the seeds germinate in 5-6 weeks. Direct sowing in the field is not recommended due to heavy water requirements of young plants. For pure stands, space at 2 x 3 m or in alternating rows for mixed stands at 1 m x 3 m or 2.5 m x 5 m. Self prunes once the canopy closes after ~5 years. May develop forks as a result of attacks by top and twig-boring insects.
