Extraction of bamboo culms

Either all the old culms, i.e. those more than three years old (six years in the case of clumps regenerated from seedling) or a certain number of mature culms are removed annually. Older culms in the interior of the clumps should be removed in a horseshoe pattern. The height of cuttings is usually at 30-50 cm above ground. It is necessary that cuttings should leave at least one node above the ground to prevent rainwater soaking into the rhizome.
