To quote the old German lady from whom I got my asparagus crowns, "Plant dem! Dey vill grow." Just make sure you give them lots of water during hot weather. Don't cut any shoots next spring. Cut a few the following spring. From the third spring on, cut, cut, cut and enjoy. Just leave a few shoots to grow into ferns. Keep your patch weeded as much as you possibly can. Asparagus hates weeds.
Good luck and keep us posted.
