Looking for some wintering advice: I have less than a dozen or so potted Chinquapin oaks as I head into a Wi winter. So, do I take these into a heated garage (45-50 degrees) or leave them in their 2.5 gallon pots outside? I will not be able to get these into the ground this year in all reality. It's hunting season and just don't want to go back in the areas where these need to go. Appreciate your thoughts everyone!
