Bamboos have an interesting method of growth. Each plant produces a number of new stems annually - these stems grow to their maximum height in their first year of growth, subsequent growth in the stem being limited to the production of new side branches and leaves. In the case of some mature tropical species the new stem could be as much as 30 metres tall, with daily increases in height of 30cm or more during their peak growth time. This makes them some of the fastest-growing species in the world[

Bamboos in general are usually monocarpic, living for many years before flowering, then flowering and seeding profusely for a period of 1 - 3 years before usually dying. The life cycle of this species is estimated at 60 years. It normally flowers gregariously for about 2 - 3 years, after which the clump dies[

Harvesting of culms may start when clumps are more than 5 years old. Culms to be harvested should be older than 1.5 years; for construction purposes, 3 - 4-year-old culms are preferred. For a sustainable yield, at least 8 - 10 old culms should be left in the clump[

The natural durability of Bambusa polymorpha is poor. Untreated, exposed culms are destroyed within 19 months by termites, fungi and borers. Traditionally, harvested culms are submerged for 10 - 20 days in running water and air dried before being used. Green culms lose about 40% of their weight when air dried[
