Can a cut the top in a certain way that the fronds will regrow, or do I have to remove the whole tree?

Question

I lost the top half of a Sylvester palm in a recent storm, still have about 6 foot of trunk still standing.

Answer 1

As long as the crown remains (which I can't see in this image) the palm should be ok. Only time will tell if it will survive the storm damage.
