Real Christmas trees typically last between 4 and 6 weeks, depending on the type of tree and how it is cared for. If properly watered and maintained, a real Christmas tree can last even longer. However, it is important to remember that real trees are a natural product, and like all living things, they eventually will die. So, while a real Christmas tree can bring a lot of joy and beauty to your home during the holiday season, it is important to enjoy it while it lasts and then make sure to properly dispose of it when it is no longer alive.
