Baldur eventually returned to life, and a joyful Freya kissed everyone that passed under the tree upon which the mistletoe grew. To enjoy cut greens for the holidays, remember that they will hold up best if placed in water and kept cool. Remember to keep holly and mistletoe out of the reach of little folk as the poisonous berries may be attractive to children.

This will work, if you remember that you can't abuse a live tree like a cut one.

Remember that the soil ball must not dry out. The air in the average home in deep December is not kind to live evergreen trees. Water will be lost quickly and must be replaced. Keep the tree outside until needed, and inside for a just a few days. Even then, keep the room at the lowest temperature possible.
