It grows easily from seed which is sown in beds when ripe, where it must be nursed before sowing in beds. Its growth is slow at first, but once the roots have taken well in a soil rich in humus it attains a great size. It multiplies naturally from its seeds and should form a third as a stock tree in the afforestation of the subtropical regions.
