overwintering blueberry cuttings

started hardwood cuttings 03/09 some of which developed roots by 08/09 and put on new growth. 18 out of 30 cuttings. Since I need to leave in propagation media until spring, how do I protect young plants over winter from freezing----zone 7 .

Doug says it sounds as if the cuttings are in containers rather than the ground (I prefer hardwood cuttings into the ground). I'd plunge the pots (bury the pots to the rims) and then after frost and the mice have gone to bed for the winter, I'd consider mulching them or protecting them with a frost fabric. Zone 7 isn't going to be too hard a winter on this plant so minimal protection should be fine.
