Can you get a picture of the plant? Is it pot bound? Try throwing epsom salt on it.

Is it in direct sun ?

Topher---yes its in direct sun,its on a south facing wall with some other palms.{{gwi:1145365}}

I WOULD WATER THE FOOL OUT OF THAT BUT I DON'T KNOW
IF YOU CAN REVIVE IT IT LOOKS BURNT UP TO ME .

Not trying to be rude but looking at your other post
Are you amending your soil with anything ? you have plenty of sand.. perhaps a little miracle grow or cactus mix
also it realy looks like you should go to lutz.com and order you some spikes because i don't think your plants are getting the nutrients they need .Bottom line water ! As dry as it is there you probaly can flood them everyday and not hurt them ! Good luck !

Topher----When I plant a palm I mix in compost with the sand amd thats it,I bought some palm food and fed all the palms last month,I will check out lutz.com.Does miracle grow really work on palms?I water all my palms once every morning because most of them are desert type palms but I was told by a local nursery that in their first season they need to be watered in morning and night to help establish the root system.but I appreciate the feedback.

Miracle grow has been so good to me what i do is i will usually keep the most of the soil that the plant was birthed in then add miracle grow potting mix not a whole lot as i have said before sand is the key to good drainage
i use the miracle grow in the yellowbag not the green i have found the moisture control stays too wet.
Lutz spikes contain magnesium, manganese and other nutrients palms need and i also fertilize with miracle grow
the bottle that mixes with water i do this every 12 days
unless we get lots of rain. It hasn't failed me yet.
Dry hot air is a killer on a lot of tropical plants !
somthing else you can try is
Take a 5 gallon bucket and punch a small hole in the side
fill with water and let the water trickle on your plants
during the hottest parts of the day don't make your hole too deep. Let me know how it turns out for you.

Whatever foliage is now brown, is lost.

That looks like a W.filifera. I would expect any Washie to do OK there for now. Is the wall particularly hot?

I once lost a T.fortunei planted close to my AC compressor. I moved an open canopy over them to shade the compressor but it trapped excess heat and killed the palm.

I'm thinking the problem you are having with some of your palms is planting them in full sun before they have become acclimated. Not to mention the heat from the wall and the pea gravel you have around some of them.

In my sandy soil, water will often run off so I also add alot of peat moss or something similiar.

Between the sand AND the concrete wall you probably have created a microclimate that is 130-140 degrees (I am not being a smart!!@?) if you come close to 100 it's getting fried by all the heat being retained by that wall especailly.
