DENVER, Colorado — We know it’s a bit early to talk about Christmas, but after Thanksgiving dinner when you head out this weekend to shop, you may want to add a Christmas tree to that list because they’re going fast. There is a nationwide Christmas tree shortage and prices are rising. Some local Denver businesses worry it could put them out of business for good. Pete Elliot, the owner of Tree Land Christmas Trees …“A month ago I found out I had no trees when I called my farmers. They said we don’t have no trees for you,” said Elliot. “I’ve done this since I was a little kid. It’s a family business. I’ve never not had trees going into my season.” …The problem started back in 2008 when the market burst. Farmers had too many trees, and they weren’t making enough money. “They couldn’t get rid of their trees. They couldn’t sell them, so they came in and just plowed and just burn mountainsides of them,” said Elliott.
