About a year ago, a friend gave me his 9 year old Yucca Palm as he was moving out of town. It did ok till last September, when it started to look like this...

I asked around and was told that maybe I was over watering it and that I should leave it unwatered for a month or so till the soil was completely dry. Then I should maybe give it a glass or so of water every two weeks.
Now it looks like this, as you can see, the three stalks are bent over and almost all the green is gone. No one I knew seemed to know what it was called, and so I couldn't really look it up on the net. Now I've learned it is called a Yucca Palm, and I see it probably needed more light than it was getting.
As you can see in the pics, it was cut off at some point or another and then painted, and then 3 stalks grew out of it. Now those three stalks are so weak, they have doubled over and I don't know what to do to save it. Can anyone help or is it just too late?
