An artificial Christmas tree can last for many years, depending on how well it is taken care of. With proper storage and maintenance, an artificial tree can last between 10-15 years or more. However, it is important to note that the quality of the tree can also play a role in its longevity. A cheaper, lower-quality tree may not last as long as a more expensive, higher-quality tree. Additionally, if the tree is stored improperly or exposed to extreme temperatures or moisture, it can also shorten its lifespan.
