Will a Jelly palm tree survive the winter outside in Delaware, zip 19939, 7 miles from the ocean?
Jelly palms cannot tolerate temperatures that drop below 10F. If it gets colder than 10F where you live, this plant will not be able to survive outdoors.
My Pindo Palm suffered severe wind damage and all forms died . Is there anything I can do to revive it?
I cannot tell you the state of your Palm from just this description.
You may want to have a qualified Palm Arborist exam the palm for you.
