Sick Palm in coastal Alabama

[JReuss]

I have a sick palm tree - looking for advice on saving it. I see a lot of brown palms here in coastal Alabama this spring but this one tree is really worrying me. I've trimmed (it needs it again), fertilized, adjusted water... It still seems sick. It's sister on the other side of the driveway is doing fine. Can it be saved?  Any help is appreciated. Thanks.  JR

Is the palm being hit with a sprinkler? Looks like the lower part of the trunk is damaged, but that doesn’t necessarily mean it’s the cause of the decline. 
 

Would cut the rest of the brown fronds off and take more in depth pics of the new growth if it’s possible for you to do so. Also, welcome to PT!

Good eyes! Yes it was getting hit by a sprinkler on the lower side by the driveway. I adjusted the sprinkler a few weeks ago so it misses the trunk now.

Trimmed it up a bit more. Here are some closer photos from the top. Thanks again for the help.

It’s hard to say what caused the decline but I wouldn’t expect this to be saved. Generally when a palm declines in this manner, it is not something that can be treated. It is usually too late. Palms that typically can be saved are ones that show minor signs of deficiency like yellowing or spots or reduced sized growth. The deficiency can be rectified with fertilizer but even then, it can take a long time to recover. This does not look like a fertilizer deficiency. It looks more like a fungal infection.
