I would plant them now, no reason to put them into garage,.. more harm can be done easily, prune the following year.

I agree, they would be best in the ground, especially with a nice layer of insulating mulch. If you are not sure where you want to finally plant them, you can plant the whole pot into the ground. That will still protect the roots from freezing too hard, but will make it easy to lift and move in spring. The last thing is to ensure that they are protected from rabbits, mice, voles, etc. They tend to like the taste of young apple tree bark, especially in late winter when other food sources are scarce. I had a number of first-year apple and serviceberry trees reduced to mere stubs by rabbits a couple years ago!
