Propagation: Propagate with freshly collected
seed from ripe fruit. Remove seed from fruit and plant immediately in clean seedling mix of 2/3 washed river sand and 1/3 peat moss or organic matter. Prick out seedlings into tubes at
cotyledon stage if possible. Seed will store if kept cool and dry and protected from insect and vermin attack, but germination drops off over time. Plants can be grown from tip and semi-hardwood
cuttings.

Regeneration use: Climax species, usually used in assisted rehabilitation projects, i.e. ecosystem has remnant value and is not fully degraded. Can be used as pioneer species. Care must be taken as plant can form monocultures and distribution should be checked (plant occurs only occasionally at limits of its range).
