This is the VOA Special English Agriculture Report.

Tall or short. Fat or thin. Real or plastic, or metal. Whatever the choice, 2,000 million dollars worth of Christmas trees were sold last year in the United States.

Christmastime in the city brings forests of trees already cut and waiting to be sold. But some people like to drive to tree farms.

Others wait for their tree to come to them. They order one from the pages of a catalog or on the Internet.

Some say the easiest thing of all is to buy a manmade tree with Christmas lights already on it. No falling needles to have to clean up.

The University of Illinois Extension service says in 2002, artificial treesoutnumberedreal ones in American homes more than two to one. One-third of homes had no tree.

The National Christmas Tree Association says 33 million real trees were sold last year, compared to nine million artificial ones. Artificial trees generally cost more, but they can be re-used. Most natural trees are cut up and recycled, but some people buy trees that can be planted.

Most Christmas trees are now grown on farms instead of in forests. 21,000 tree farmers in the United States grow Christmas trees on more than 180,000 hectares. Oregon was the leading producer last year.

The Illinois Extension says the trees take seven to ten years to grow. The most popular pines include Scotch¹, Virginia and white. Other big sellers are Fraser, balsam and Douglas firs.

22 percent of people who bought real trees last year chose them at a farm. Two percent of those people cut the trees themselves.

The next most popular places were big stores like Wal-Mart and Home Depot². Groups like the Boy Scouts³ also sell Christmas trees.

But some people pay nothing for theirs. They steal it.

Cornell University in Ithaca, New York, has many prettyevergreens. Some years ago, a university employee found a way to keep them there. A month before Christmas, workers treated them with "pink ugly mix."

It contains water, hydrated lime⁴, a treeprotectantand red food color. The bright color starts to disappear after about a month. It can take longer, however. Cornell decided⁵ not to use the mix this year, but the idea has spread.

Some places protect their trees another way. The University of Nebraska at Lincoln uses a mixture made with fox urine. The trees smell fine in the cold air, but not in a warm home.
