The Christmas tree should be removed within a week of Christmas, when the holiday festivities have come to an end. This gives the tree time to slowly dry out, which helps prevent it from becoming a fire hazard. Once the tree is dry, it can be disposed of in a safe and responsible way. In some areas, there may be designated areas for disposing of Christmas trees, such as a recycling center or local landfill. Alternatively, you can repurpose the tree by turning it into mulch for your garden or using it as a bird feeder.
