A fake Christmas tree can last for many years, depending on how well it is taken care of. Many fake trees are made from durable materials like PVC or polyvinyl chloride, which are designed to withstand the wear and tear of multiple holiday seasons. As long as it is stored properly and kept clean, a fake Christmas tree can last for up to 10 years or more. However, it's important to inspect the tree for signs of damage or wear before each use to ensure it remains safe and functional.
