My 4year old....old hami is doing great it is about 25ft tall 2.5 dia. My question is the shots from last year are starting to branch out, i like the bottom 6ft of the bamboo plant to be branch free is it bad to break off the new branch growth from the shot?? I do it as soon as i see it starting to grow, so it is still very tender and comes right off with a pinch leaving a clean 6ft bottom to the bamboo..Basically it shows off the size of the bamboo and it still has branches on the top 20ft of the plant
