If you're concerned about the impacts of your tannenbaum on global climate, consider renting a living tree that spends two to three weeks in your home over the holidays, then summers at business parks or other locales. If you're looking for a long-term relationship with a single tree, some companies will bring back the same tree year after year. You should start with something small, through. The trees grow between two and three inches per year, and your living-room ceiling probably doesn't.
In other cases, rented trees are permanently retired to a nice farm or city planter after a single Christmas with a family. Before you decide to rent, be aware that you might not get a classic Christmas variety such as the Douglas fir or Scotch pine. Many companies offer less traditional species including the small-leaf tristania. You should also seek out a local farm, minimizing the gas burned on the way from the farm to your home.
