If you are thinking of just buying a tree and planting it again, a word of caution from Jim Tolstrup, Director of the High Plains Environmental Center. Many species may look great but may not be suitable for your area and often do not survive the planting. He first recommends finding a locally appropriate tree that still looks good. In parts of the West, Douglas Fir trees are popular. The East Coast is great for the Balsam Fir, Eastern Red Cedars do great in the South, and Austrian Pines are a good choice around the Rockies. Another popular indoor plant is a sheared rosemary bush. He also does not recommend that the tree be indoors for very long, especially in cold regions, so instead Jim suggests planting the trees in your yard. You can then decorate them with edible garlands made from cranberries and popcorn and bird seed ornaments to create the ultimate green Christmas tree.
