Once all of the ferns have died down on their own (usually at first frost, but even without frost in areas that do not get frost), cut the ferns down to about 2 inches above the ground. Add several inches of mulch to the bed; compost or rotted manure is ideal. There is no 鈥渢ransplanting them elsewhere.鈥 The ferns grown from crowns that are not usually divided and have, by now (in your case, after three years) very long roots. You’re growing asparagus! Enjoy it!
