KUSA - You'll find many tips online about how to keep a Christmas tree fresh. When you ask the people who know--Christmas tree farmers--they'll tell you how to keep your tree fresh: water. After re-cutting the base (so that the tree can absorb moisture) use fresh water and change it frequently.
Avoid sugar in the water. Plants can't use processed sugar and it just leads to a fermenting mess.
In addition, an anti-desiccant spray such as Wilt Pruf or Wilt Stop helps to seal in moisture and prevent needle drop. Spray the tree--as well as wreaths or garland--when it's above 50 degrees and allow it to dry before decorating. If it's too cold outside, spread newspapers or plastic and spray inside. The non-toxic spray is made from pine resin.
Living trees should only be brought inside for a maximum of 48 hours. More than that and their winter dormancy will be disrupted. If the soil is already frozen where you intended to plant a live tree, keep the potted tree outside in a place protected from wind and water frequently all winter until there's a thaw. An anti-desiccant spray will also help a living tree from getting damaged from extreme cold and moisture loss.
