The cost of a real Christmas tree can vary depending on the size, species, and quality of the tree. A small, 6-foot tree can cost around $60-$100, while a larger, more premium tree can cost upwards of $200 or more. The cost also depends on the location and availability of the trees, as well as any additional costs such as delivery or installation. Additionally, the cost of maintaining the tree, such as watering and adding lights, also needs to be taken into consideration.
