North Carolina is the state that grows the most Christmas trees in the United States. According to the National Christmas Tree Association, the state produces approximately 30% of all Christmas trees grown in the country. The state's mild climate and fertile soil make it an ideal environment for growing a wide variety of Christmas tree species, including Fraser firs, balsam firs, and Virginia pines. Additionally, North Carolina's proximity to major population centers and transportation infrastructure makes it easier to get the trees to market.
