If you choose a live, balled Christmas tree this holiday season, consider leaving it outdoors instead of bringing it inside. A live evergreen can be replanted in your yard after the holiday season, but it has limitations. On average, a live tree can last one week indoors before it gets too acclimated to the warm temperature. Any longer than a week and it will die when reintroduced to the cold air. By leaving a balled tree outdoors -- perhaps by the front door -- you can decorate it early and leave it out all winter long, or until it's warm enough to plant.
