The lifespan of a real Christmas tree depends on a variety of factors, such as the type of tree, the conditions it is kept in, and how it is cared for. On average, a live Christmas tree can last anywhere from 4-6 weeks, but with proper care, it can last longer. Some people have even been able to keep their real Christmas trees alive for several years by properly watering and feeding them. However, it is important to note that even if a real tree does not last the entire holiday season, it can still be enjoyed for several weeks, which is plenty of time to spread holiday cheer and create lasting memories
