Here's a question: You know that bamboo that is sold in stores as lucky bamboo usually placed in a shallow/narrow bowl of gravel? Well, is that a good way to keep bamboo? Personally I think it isn't because everyone I have known with it ended up with a dead brown stalk over time. So how would one grow a stalk (stem?) of bamboo indoors? I looked it up online and didn't find anything conclusive. Thanks!
