The real history behind the upside down christmas tree remains quite vague, very little information is known about it.
The trend of hanging the upside down christmas tree has changed, the point of the fir tree pointing up to heaven . Many people believe that an upside down christmas tree is a sign of contempt.
Upside down christmas trees were popular for a short time and were originally just used as ,a marketing gimmick. It enabled customers to pick ornaments off easier and more conviently.
One other note on christmas trees while we're on the subject:
Christmas trees were not to be brought out and decorated until Christmas Eve (dec. 24th), rather than the first day of christmas (dec. 23rd). They are then to be removed after the 12th night which would be January 6th. To have your tree up before or after these dates was considered bad luck...just a thought for you :)
