I recently inherited a 10' potted indoor bamboo plant from my boss. It wasn't thriving there so he gave it to me to try to revive. Of course as soon as I take it, it takes a turn for the worse!!

I don't know if it's not getting enough sunlight, not enough water, too much water, are the windows too drafty, is my apartment too cold? What's going on! I thought these things were pretty resilient. Shows how much I know!

I water it a good amount about once a week and it is in a north facing room which gets light, but not a ton of direct light. There is still slight new growth, but all the ends of the blades are dying. and quickly.

any help would be wonderful! this plant is a beauty, I'd hate to be sending it to its demise!
