they will re-grow in the spring no reason to dig them up

Thanks Logan I still haven't had a killing frost yet should I cut it off and mulch or wait for it to get bit by a freeze or does it matter

What variety is it? Hardy Basjoos should make it along with a few others, but zone 6 is really pushing it except for the hardiest. Of course, it depends on you level of protection and other quirks of climate and weather (like how wet your winters are).

Not sure of variety . I'll roll the dice I cut it off and covered with 2ft of mulch and then set 2 bales of straw on top of that ,left the bales tied so we shall see , thanks for the info will report this spring

If you can keep the ground from freezing, your chances should be good. A big pile of leaves can certainly help with that!
