Growth—

Plants may commence flowering when 3 years old[1]. Flowering and fruiting take place more or less all year-round[1]. The wood is brittle, the branches breaking off easily in strong winds[2]. Regular pruning seems to be tolerated[1]. Natural regeneration is generally profuse and seedlings can survive under shade for several years[1].

Propagation

Seed - should be sown fresh from the fruit, on the surface of loose soil and under shade[1]. It should not be buried, as this seriously reduces the germination percentage[1]. Germination is rapid, starting 1 - 3 weeks after sowing, and is complete after 5 - 12 weeks[1]. The seed loses its viability very rapidly and after 4 - 6 weeks it hardly germinates[1]. Wildlings can be collected from under adult trees, they should be hardened off in a nursery before being planted out[1]. Cuttings Air layering.
