The life cycle of a Christmas tree from the seed to a tree takes, depending on species and treatment in cultivation, between eight and twelve years. First, the seed is extracted from cones harvested from older trees. These seeds are then usually grown in nurseries and then sold to Christmas tree farms at an age of three to four years. The remaining development of the tree greatly depends on the climate, soil quality, as well as the cultivation and how the trees are tended by the Christmas tree farmer.
