The lifespan of a Christmas tree can vary depending on its species and how it is cared for. A properly maintained tree can last several weeks or even months. However, most trees are typically discarded after the holiday season is over. If you want to extend the life of your tree, there are a few things you can do. First, ensure that you keep the tree well watered and away from heat sources. Additionally, consider treating the cut end of the trunk with a preservative to prevent it from drying out.
