Bamboo is a grass which grows fast and can get 20 to 30m in 3 to 6 month depending on the species.
For 3 to 5 years the bamboo will grow wall thickness and is mature to be harvested for construction.
Out of one clump of bamboo, an average of 20-30 bamboo culms can be cut yearly.
Everytime a pole is cut about 50-60cm from the ground, another shoot will grow directly out the clump.
Maintaining by cutting bamboo will allow the poles more space for the other culms to grow, straight and strong and will give a boost of energy to the plant.
