why does my christmas tree not smell

It seems like your Christmas tree has lost its fresh pine scent. This can happen when the tree is cut too far in advance of the holiday season or when the tree is not properly hydrated. To restore the scent of your Christmas tree, try placing it in a cool, well-ventilated area and misting it with water daily. You can also try spraying your tree with a Christmas tree scent spray to give it a fresh, piney smell.
