There are numerous pros and cons of buying a real Christmas tree. First, artificial Christmas trees, typically made with plastic or metal, are created and shipped from China. Only 10 percent are made in America, but that 10% support local economies and keeps our money in America.
My favorite pros for real trees are supporting local family tree farms, creating jobs, they are environmentally friendly, and they smell good. There are around 10 Christmas Tree Farms in Montana, and 25 in Nebraska. You can also get a permit from the National Forest Service to cut your own tree -- go for a great hike and come home with a nice tree. The biggest con to a real tree is needle drop and the cleanup that goes with it.
Once inside, keep the water bowl for your cut tree full at all times. Even a cut tree takes up a lot of water. Water helps keep the needles attached to the branches requiring less cleanup. For easy cleanup, I recommend using a broom instead of a vacuum cleaner, even on carpet. Most cities, like Cheyenne, have a recycling program for Christmas trees, making disposal easy.
