Hey y'all...

I just inherited a palm of some sort from a friend of mine, and it has very brown leaf tips. I've heard that a good way to prevent brown leaf tips is to make sure the humidity is high enough; often spraying the leaves with water every once in a while can do the trick. However, will it bring the brown leaves back to normal, or is it a lost cause? If the spraying won't work, is there any other way to rescue the leaves?
