Trees in pots

Anonymous added on September 11, 2015 | Answered

I have two small blue spruce trees (18" high) planted in large pots, which have been outside framing the front door(faces southwest) since spring. Will I need to winter these inside or in an unheated garage or what would be the best choice? Some winters we can get as cold as -20.

    You will not need to winter the trees inside.
    The are winter hardy to zone 3.
    Continue to water the trees into the dormancy and add a small amount of water a few times throughout the winter.
