I've had it since may 2015 but since april that I changed workplaces and kept my bamboo at home it just kept getting worse. I blame it to the weather, it's really hot (above 100ºF) and I can't take it to work since the AC doesn't work there are is even hotter than home.

First one stem turned yellow and now its neighbor is too; it could be the light, the hot temperature or maybe lack of water from time to time (i usually am not home so I haven't been paying it attention either). I used to add liquid fertilizer every month a few drops but I haven't been doing that as constantly this last months that I changed work.

Maybe I should have gotten a bigger pot? Please help
