What's the use of arhat bamboo? Why did you die after flowering?

"Broke my heart" makes sense. Arhat bamboo is an ornamental bamboo, which can be made into many different handicrafts. The average life span of bamboo is about 40 years. After flowering, most of the nutrients stored in bamboo vegetative organs are consumed and will gradually die. The only way to save lives is to cut all the bamboos immediately when you see them blooming, so that new bamboos can grow from them next year.
