We will be rolling out several small fixes mid-day today (Jan 29.) We do not anticipate any disruptions or problems, but f you spot any unexpected issues after 12 noon (PST), please report them in the designated thread in the DG Site Updates forum.
Pandanus utilis can be propagated by seeds, but these are not easy. 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 about 10" tall and ready to be planted out.
The common screwpine (Pandanus utilis) is, despite its name, a tropical tree and not a pine. It is native to Madagascar, Mauritius, and the Seychelles.
In nature, the screw pine grows on the seashore and around tidal lagoons. However, it will tolerate drought, and is very salt tolerant. It will grow faster if it receives plenty of water. Although young plants will tolerate shade, full sun is required for fruiting. Small trees, six to eight feet tall, can be grown in large pots.
