Answer
Hi Tom,
Thanx for your question.  I'm really not a berry expert but I would protect them the same way you might protect other young perennials.  Give them a good straw mulch.  If they have been rooting as long as you indicated, they should have a substantial root system on which to draw water and nutrients.  You indicated that there is new gowth and Zone 7 winters are fairly mild compared to zones farther north.  So, if the plants are growing outdoors in a nursery bed, mulch with straw and I think they have enough root growth to get through the winter.  If they are in a cold-frame propagator or hoop house that you can shut doors or cover with plastic, that should be enough protection until spring.  Can you tell me your location?  I can probably find you some free, local advice.  I hope this helps.
Tom
