I just stuck the top in a plastic cup of water so the water just covered the part that used to be in the fruit. Then about two weeks later, I put it in soil. I pretty much have a 'black thumb' so if it works for me, it will work for anyone.

Try Riverwalk Nursery for Bamboo Plants. If they don't have it, they will try and get some for you. Be sure to talk to Immer. The young girls that are usually there aren't very helpful.
