The lifespan of an artificial Christmas tree can vary depending on the quality of the tree and how it's stored and maintained. A well-maintained artificial tree can last for several years, even up to a decade or more. However, it's important to take proper care of the tree, such as storing it in a cool, dry place and avoiding damage or exposure to extreme temperatures or humidity. Additionally, it's a good idea to keep the tree clean and free from dust and debris, which can accumulate over time and affect its appearance.
