A real Christmas tree can last anywhere from one to three weeks in your home. Depending on the type of tree, its freshness, and how well you care for it, it can last up to six weeks. To extend the life of your tree, make sure to keep it away from heat sources such as fireplaces or heaters, give it plenty of water, and try to keep it away from direct sunlight. With proper care, your tree can last for weeks to enjoy the holiday spirit!
