Since it's only a year in that location, it should transplant successfully. Wait until the ferns are completely brown, then cut them to the ground. Use a fork, not a spade to dig the roots, this will help remove them with less damage. Get as deep as you can.

Good luck.

I have had to move a couple of 3-year-old asparagus plants, and I dug them with the soil still packed around the roots and put them in holes in the new spot. They settled right in and produced a crop the next year.
