During the two winters we had where the temps dipped below freezing for several hours several times, I noticed the queen palms in the northern areas of TV showed more damage than those in southern villages. I live south of 466 and have 9 queen palms. I had 10 but lost one due to disease. My temps always seem higher than the official temp so maybe I'm in a microclimate that helps my palms survive.
As I look around my neighborhood, there are many queen palms and all are doing well. So, the extension advice may be technically correct, but may not apply in all situations.
As far as landscape rock, I have that too. The advice above to keep the rock away from the trunk of the trees and plants is accurate. The rocks can get hot enough in the summer to actually burn the stem/trunk of the plant.
