A 200 to 250 cm tall Nordmann fir Christmas tree has grown for 10 years in the Christmas tree stand. During these 10 years, the Christmas tree has been touched 40 times by a human hand in connection with planting, shaping, harvesting, etc.
Moreover, machine tools have passed the same Christmas tree approx. 42 times in order to perform the necessary weeding, fertilization, etc.
With good reason, you can say that the Christmas tree has become "something of a tango-dancer" before it is brought into the living room for Christmas to be decorated by children, parents and grandparents.
