That's a great question! Generally, Christmas trees are taken down after the holiday season, usually within a few weeks after Christmas Day. Some people like to keep their trees up for the full 12 days of Christmas, while others prefer to remove them as soon as possible. The decision ultimately comes down to personal preference and what works best for your household. However, it's important to remember to properly dispose of your tree after the holidays, so it doesn't become a fire hazard or contribute to pollution.
