How can I cut fresh holly and preserve it to send to my Marine?

Answer 1

Try Michael's,Joanne's Fabrics, Hobby Lobby, they should have a powder preservative to dip the holly in, to preserve it.

Answer 2

Mail regulations as well as custom regulations are rather strict on agricultural materials.

The source provides the details. But you must mark the package with the contents.

I would say go with silk or plastic substitutes.
