Selective harvesting of about 1/5 of the culms per year, only the ones that are more than 3-4 years old. This is tropical bamboo (Asper), in Southeast Asia, but I'd rather not be specific, to avoid embarrassing anyone. You might get away with this if you were harvesting Bambusa vulgaris (indestructible), but not Dendrocalamus asper.
It's supposed to be only mature culms, right? Is this in Europe?
