I have a black bamboo on my balcony in the West End. I planted it two years ago and it did very well until about three weeks ago. It does get some dry brown tips on its leaves during the winter, but otherwise, it had always looked great. I wrap the pot up in the winter to prevent frost damage. Currently, it stands about 8 feet tall. I have to admit, I have never fertilized this plant (my bad). Since I live in an apartment with limited storage, I simply can't be buying a huge container of lawn fertilizer. I do have a general pourpose fertilizer, but do not know whether this would be okay to use on the bamboo. So, back to the problem: Three weeks ago, I noticed that all of the leaves had a papery quality to them. It had been very windy the past few weeks. The whole bamboo was bent horizontally as the wind gusts blew accross my balcony. Also, the humingbird feeder spilt lots of it's sugar water on the plant during the wind storms(yes, I do get hummers all year round!). I thought that this coating of sugar may have been a problem, so I hosed the hole plant down last week until the leaves were clean. Still, no improvement of the leaves. What could be the reason for this? I love my plant and don't want to loose it. Any suggestion are appreciated!
