Why is my palm tree dying?

I have used a special [palm tree fertilizer](https://www.miraclegro.com/smg/goprod/shake-n-feed-palm-plant-food/prod11850032?locale=en_US) and it didn't help it at all. The tree was already looking like this just not as bad before I used the fertilizer. I actually didn't use much just sprinkled some around the bottom of the tree. This is in Mobile, AL

How can I save it?
