Here's a picture of my Coccothrinax. Most of the leaves are all brown and scraggly looking. Though the spear and the newest leaf that has started emerging still look healthy.

This is some sort of Coccothrinax hybrid but I think it looks most like Macroglossa. It has been planted for about a year and seemed to be doing fine until a month or so ago.

What could be the problem? Too much sun? lack of water? fertilizer? Is it planted too high. Should I replace the stones around the base with mulch?

 

Doubtful it's too much sun if it's been planted for a year.  Cocos love full sun.  

Lack of water...

I was thinking lack of water too. These palms are drought tolerant not drought resistant. Even with irrigation 2x/week I have palms in my back yard jungle with frond die-back. Tonight I spent over an hour hand watering. Next week Cape Coral drops me to 1x/week irrigation. I will be watering like crazy. FL is in a terrible drought and needs rain desperately.

Lack of water. 

Agree with the above comments.

I am not sure it is lack of water, look at the grass around the palm, still green. I would think the grass would be brown if this palm was not being watered. Here in Cape Coral, you can really tell who waters and who does not especially with the bad drought we are in, the lawns are totally fried. Almost looks like a chemical burn, or herbicide? 

I would bet that is fertilizer burn. Look at how green the grass is just to the left. Good thing is, it survived, and should power right out of it. Try a little lighter dose, and spread it out a little more.

My two Coccothrinaxes and a Coccothrinax-Zombia hybrid have thrived on neglect.  I wonder whether there might have been a short dry spell--it might not yet have its full root system. 

My only "fertilizer burn" problem resulted from trying to correct an Archontophoenix's problems with what turned out to be too much epson salts and borax.  Even a native shrub next to the palm was harmed.  

Ok so the consensus seems to be to not put any more fertilizer and water it more.

Rootball from original planting may be somewhat "water resistant" if it contained a lot of peat.New roots probably have not established yet.Drag the hose over and let it drip next to trunk for several hours to get the rootball wet.
