Nearly 1 million Christmas trees are sold annually from Oregon's largest tree farm.

There is surely no shortage of Christmas trees in Oregon.

According to World Population Review, Oregon is the largest producer of Christmas trees in the United States, with an annual harvest of approximately 4 million trees. This accounts for about 33% of the total amount of Christmas trees produced in the country each year, as per the National Centers for Environmental Information.

That number equates to around $120 million annually, per the source.

Holiday Tree Farms, located in Oregon, is the world's largest Christmas tree producer, with 15,000 growing trees across the United States, as per the National Christmas Tree Association.

Holiday Tree Farms was established in 1955 by the Schudel family.

According to the Holiday Tree Farms website, the farm covers an impressive 8,500 acres and harvests 1 million trees annually.

The farm's 12 processing yards hire approximately 600 employees during harvest season, according to the website.

Several types of trees, commonly used in homes during the holiday season, are found on the farm, with the most popular being Douglas fir.

According to the Holiday Tree Farms website, Douglas firs grown at their farm are not only sold to Oregon residents but are also shipped across the United States and exported to countries such as Mexico, Guam, Asia, and Central America.

According to their website, Holiday Tree Farms grows Grand fir, Noble fir, and Nordmann fir trees in addition to Douglas firs.

North Carolina ranks behind Oregon in tree production, producing approximately 4 million trees annually and generating $86 million in revenue, according to World Population Review.

In the US, approximately 25 to 30 million real Christmas trees are sold annually, according to the National Christmas Tree Association, with around 350 million trees growing nationwide.

Growing a Christmas tree is a challenging task. While an average sized tree of six to seven feet can take around seven years to grow, it may take up to 15 years to reach maturity, as per the source.

During the fall, trees are harvested for the holidays, and in spring, farmers replace them with one to three seedlings, as stated by the National Centers for Environmental Information.

From there, the slow growing process of the freshly planted trees begins.
