I think everyone should be fine as long as the temps aren't below 15°. Smaller trees are best on the ground while larger tree should be ok up to that point, in theory anyway. I know when temps get to around 25 I put most on the ground and then spray and mulch around the pots. Less hardy stuff I put next to the house. I don't like putting anything in a shed or garage because my weather here can get in the 70's on weird days and then down to the low twenties that we had last night. It's a fun run around game I have to play. At least the larger pine/spruce are good to go as I rarely move them, unless they're newly collected, then they just get put on the ground.
