I have 3 queen palms growing in a planter around my pool that have been there for 7 years. This summer we lost one and those say it was due to lighting. the other two remained healthy until a few weeks ago when one started turning brown and now all of the fronds are brown. Is there anything I can do to save this tree? I can only imagine what is going to take to remove them and put in new ones! please help anyone!! thanks!! I can post a picture if that would help
