WASHINGTON — O Tannenbaum, O Tannenbaum, Wie treu sind deine Blätter! Oh Christmas tree, Oh Christmas tree, thy leaves are so unchanging.
Christmas trees have become the traditional focal point of holiday traditions, and they are an important part of American agriculture. They're grown in every state, planted on more than 350,000 acres, on 15,000 farms. More than 77 million are planted each year, at 2,000 trees per acre, and they normally take six to eight years to mature. Normally, three seedlings are planted for every tree. . .
