Well I am NOOOOO expert, but unless that is a heated garage, I would put them in the basement. I am guessing you get more than a few days of under 40º in the winter.
Again, no expert here, just my opinion!

As iowajo says, temperature is important. Do you have any way of knowing what your low temp was in the garage? Also your average temperature. They really need to stay above 50 degrees; 55 is even better. Maybe you need additional heat, plus you need to keep them all higher up, like closer to the ceiling? Were they getting any light? Did you water in winter? In early Spring? Need more information to help.

No extra heat or moisture was supplied. Placed on the floor. It never freeze's at least the beer and soda pop don't. Thanks FTH

The cold of the earth in winter comes right through concrete. Even here in Calif. I put my tender plants on 1" foam insulation to keep them off the concrete in the winter. You might put a 100 watt light bulb in the container and turn it on when the weather in the garage is cold. I am not an overwintering expert because my plants stay outside all winter and I have to worry only about an occasional frost and high winds. But I do know that putting pots on concrete in the winter is not a good thing. Bill
