Bamboo in trough
I've got a bamboo (Robusta, I think) in a wooden trough. After copiously feeding and watering it for last two years, it has reached over 10 feet in height. Glad its not in the ground. I want to gain some control over it. Would it respond well if I lop off its height? Somebody once told me that bamboo is just like any other grass so I can trim it back without too much harm. Is that true?
