Is this plant dying?

I am not sure what this plant is. Also, it looks like it is mostly dead. Should I try to repot it, or just toss it?
Thanks for all your help.

It's a ponytail palm and looking at the base, it must be pretty old. Do you have it inside in dry air? How much water are you giving it (they don't need much). Check your soil to make sure it's not too wet or dry. Also, I don't give mine very much fertilizer at all. Since there is still green at the top, I would at least try to save it. Cut off all the dead leaves and just leave the ones at the top that are still green. I already have mine out on my front porch where it always does much better than it does inside so maybe your temps are O.K. to put yours outside. Hose the leaves off to make sure they aren't choked with dust if it's been inside. It might make a comeback. I hope so--they are such a beautiful plant.

Thank you, NatureLover, for your advice. I have it in the bathroom on the tub in front of a window, so it gets a lot of light. But maybe not enough. I thought the humidity would be okay, since it is in the bathroom. Maybe it is potbound, but I am afraid to repot. I did fertilize with houseplant fertilizer in the water, so maybe I fertilized too much. I will take it outside and see what happens.

I have this plant too. It is presently in a pot in the house and there are actually 5 ponytails coming from one location. It thrives on very little water. I don't think there is any such thing as being pot bound as I have heard this plant grows to the size of the pot. I am getting ready to separate mine and put in bigger pots so I can get a bigger plant.

The humidity might be causing a problem. These are not humidity lovers. When I have to bring mine in for the winter, I put it in a west-facing window in my bedroom where it survives until I can put it back on the porch. Normally, plants that have a large base like pony tail palms do store water in the base so they don't need to be watered a lot. It's good to try to keep the dust washed off the leaves but with one the size of mine (it's 24 years old), it takes an act of congress to move it back outside just one time during the winter (on a warm day) to hose the leaves off. Hubby is going to build me a box with wheels on it so moving it will be easier. Also, I fertilize mine once it the spring when I move it outside with liquid Miracle Grow and then one more time in the middle of summer. Plants usually go into a rest period during the winter so it's best to fertilize them during the warmer months when they are actively growing. Mine is so big now that I hope it can live in the pot it's in for a very long time--don't know if I can afford the next larger size pot for it, LOL! It's huge. I really hope your's will live for you.
