Picea glauca are extremely cold hardy, Zone 2 I think. You should be fine.

Hello, I'm In zone 5 I think - Long Island NY. I just picked up 2 live 5'
tall
dwarf Alberta Spruce shrubs on closeout. (Already decorated for Christmas,
lights, bows, etc.) They're in only 5 gallon pots, which I think for the
height, 5' and the width at the base (30") is a little small. I'll have
these
on my 2nd floor deck until the 1st week of Jan, then intend to heel them
in at
the first possible opportunity.

I was wondering I'f I'm better off buying a couple of large tubs and some
soil,
and just set them in those NOW, and leave them till spring. The tubs would
be
punctured for drainage and hold at least 4 40 lb. bags of soil each. My
fear is
the pots they were sold in just aren't large enough to hold and provide
adequate moisture, even with diligent watering.

TIA
