Cultivation Details



The tree does not flower until it is mature. A flowering shoot is produced from each node on the stem, commencing with the node at the top of the plant and working down to the base. Vegetative growth ceases when the first flowering shoot is produced, and the stem dies once flowers have been produced from the basal node[

Edible Uses

The taller Arenga palms store large quantities of starch in their stem that are later converted into sugar to be translocated to the inflorescences. The sugar can be drawn off in the juice by tapping the peduncle and rachis of the male inflorescence. By far the most important sugar producer in the genus is Arenga pinnata, but other species are used similarly. The starch of the stem can also be harvested[

Propagation

Seed - a deep root is formed before the seedling emerges above soil level, and so the seed should be sown in individual, deep containers. Pre-soak the seed for 24 hours in warm water before sowing. It can take 3 - 6 months or more before signs of growth are seen above soil level[
