Hi Kelly
to NGA
My Dad transplanted full grown palm trees all the time and with great success. I have followed his instructions and transplanted a couple myself.
After transplanting, he put a dripper in the top of the palm where the leaves emerge and let the water drip for a couple weeks until he started to see signs of life.
I don't know if its too late for your palm but if you can extend that drip line so it is dripping onto the crown and down the trunk, you might have better success.
