We have a dozen first year pear trees in 1-2 gallon pots; planting them this fall is not an option on our farm. (The trees would still be called seedlings I'm sure, they are very small in diameter and at the most 15" tall.) I've been told to place them in our garage, which will stay around 40 degrees through the winter months. My question is when do I place them there? We are in zone 6 and it's going to get into the low 20s a couple nights from now. So far we've had one hard frost, but the trees are on our covered patio, so the frost didn't get to them and their leaves are still green. Do I put them in the garage with green leaves? Do I need to leave them out from under the patio on a couple of these upcoming cold nights first? I figured some of you guys would have been through this process before.
