hello there!

when is the best time to top bamboo??

i have a phylostachys nigra nenonis which has just shot up some massive culms in the space of 2weeks!! absolutely stunning, 1 inch thick and around 2 meters high! the only problem is i cant have them taller than this.. should i clip the tips now to stop upward growth, or leave it to grow fully and mature before topping??

will i damage the canes if i top now?

thank you for your time folks!
