The birth of the holiday took place in the United States in 1840, when J. Sterling Morton moved to Nebraska. There, his eyes opened endless prairies with lonely trees.

Morton, later editor of the first newspaper in Nebraska, suggested that Nebraska citizens set a day to be dedicated to landscaping - a kind of Tree Day.
