That's a great question! The tradition of decorating a Christmas tree can be traced back to pre-Christian times when people would bring evergreen trees into their homes to celebrate the winter solstice. In the Middle Ages, people would decorate these trees with edible items like fruits and nuts to represent the bounty of the harvest and to ensure a good crop the next year. Today, Christmas trees are a symbol of the holiday spirit and a beautiful way to add a festive touch to your home.
