I'm hoping someone out there can help me with this. I just moved into a condo and the person before me left this bamboo plant on the balcony. There is quite a bit of brown and most leaves look like they're dying (aside from the new shoot sprouting up). I'm not sure what I should be doing but I really like it and would like to save it/keep it growing, if possible. I've never had any sort of plant before and have been doing some reading but am a bit confused on what type of bamboo this actually is and how often/how much I should be watering it.

There was also this smaller plant inside which seems to be doing fine. It's in pebbles. I'd like to keep it going strong and I'm not sure how much/how often to water this one either.

Any help/advice is greatly appreciated :) thanks so much!
