Christmas wreaths can last for several years if they are stored properly. To extend the life of your wreath, keep it in a cool, dry place, and avoid exposing it to direct sunlight. Additionally, wrapping the wreath in plastic wrap can help to preserve its freshness and prevent the leaves from drying out. If your wreath does start to look a bit dry, you can revive it by misting it with water and gently shaping the branches back into their original shape.
