If you lived here, I would say pot them up and leave the pot outside till spring. As far north as you are, chances are you will need to either put your pot in an unheated garage or wrap it with some type of insulation. If you don't plant the bulbs somewhere they will be lost. I'm sure others will chime in with zone specific advice.

If the ground has frozen, you might consider buying some bags of soil, and planting them shallowly above ground level, and topping them off with some mulch if you have it.

They would have a much better chance of survival that way.

You could also consider planting them in a large container, like an old wheelbarrow or an old tub, or plastic bin, with holes for drainage.
I would not try thawing using water. I'd think it would be impossible to plant in mud.

Sue...who hopes to plant today!

Actually, the water idea would work...but I would use hot water and sufficient amount to thaw down 6 - 8 inches--the level where you would like to plant your bubls.
Otherwise, you are facing having to dig.

Mud is only mud when too much water is allowed to stick around. It will freeze pretty quick afterwards.
Some home-grown or otherwise compost in the hole will take up some of the mud where the bulbs are then planted.

You cant put bulbs in a container and expect them to not freeze...and they must be watered and the water must go to the bottom of the bulb to initiate roots.
Without roots, they're useless and wont survive spring thaw.
Over the soil mulch them well to hold as much temperature as possible while the bulb produces roots.

You cant plant bulbs in a container and place that in an unheated garage. The garage is open to th eambient temperature and when watered, the soil and the bulbs would surely freeze solid before they had a chance of production of roots.
If the container can be kept from freezing, then it stands a chance of holding bulbs long enough to initiate roots.
A covering of cardboard, surrounded by a covering of aluminum foil and protected from the sun and from wind, it might come through winter. But the best place is in the ground.

You know, I read postings like the above and I am astounded. jeannie7, do you have any idea how many folks plant spring flowering bulbs in containers? And very successfully? And in all climate zones? They write books on the subject, for heaven's sake!

To the OP: plant them up in a suitably sized container(s) with decent potting soil. Water once well and store in your garage, crawl space, cellar or unheated basement. As long as they protected from the elements and any freeze/thaw cycles, they'll be fine. Unheated garages that are attached to the residence DO NOT experience the same temperature fluctuations or severity of temperature as do open areas - there is such a thing as heat conductivity.

You may need to check soil moisture a couple of times during the winter to make sure the soil doesn't dry out excessively but that is unlikley to happen in an unheated indoor space - evaporation at this time of year is very low. Once tempertaures start to warm in spring, bring them out into the open, water well and enjoy. Once the flowering is over, these bulbs can be planted in the ground in a suitable location and enjoyed in future springs.
