Cultivation
- Generative propagation is by seed, and vegetatively by cutting. Optimal germination is obtained by using ripe seeds, dried in the shade, and with the testa removed. Seeds are sown directly in moist and shaded nursery beds and germination follows within a week. Seedlings are ready to be pricked out into individual pots about 2 months later. They are kept in a shaded nursery for another 2-3 weeks and subsequently planted out in the field. Field planting should take place in the wet season to avoid moisture stress.
- Cuttings 10-15 cm long are taken from internodes of branches with a diameter of about 5-8 mm. They should be placed in a shaded container or in a bin, and the soil and air should be kept moist by spraying. The cuttings are inserted in the planting medium to a depth of about 2 cm.
