A photo would be helpful. Not sure that it is over watering. These palms often grow near water, and it is hard to overwater them especially if they are in direct sun.

Did you recently put it out in direct sun from indoors?

have phoenix rubellini in san diego moved them 10 feet in june not alot of sun in san diego in june/ 3 miles from ocean used palm dirt/miracle grow dirt/and mulch and exisisting soil. lots of h2o . leaves getting darker. some roots had to be cut since they were wrapped around sprinkler pipes. to much h2o/shock/ roots cut? any suggestions out their would be appreciated.

I am also having the same problems. My palms take roughly 5-6 hours of direct sunlight and are watered 2 to 3 times a week, my plants appear light yellow and do not look healthy. I could also use some help...
