Home Depot offers a variety of Christmas trees, ranging from artificial to real trees. The cost of a Christmas tree depends on its size, type, and whether it's artificial or real. Artificial trees typically range from $10 to $500, while real trees can cost from $20 to $300. Real trees typically come in different sizes, such as 6ft, 7ft, and 8ft, and the price may vary depending on the size and type of tree. Artificial trees may be more expensive, but they offer the advantage of being reusable and not requiring any maintenance.
