Mode of Propagation
How to plant/cultivate
Pandanus utilis can be propagated by seeds, but these are recalcitrant. Pre-soaking of the seeds for 24 hours before sowing is recommended for Pandanus in general. The germination rate is usually over 50%. Seedlings emerge about 4 months after sowing. After 12–16 months they are 20–40 cm tall and ready to be planted out. Propagation by stem cuttings and suckers is also possible. In Réunion, planting in April or May at spacings of 1.5–3 m is recommended. [3]
