If you had a real Christmas Tree this year and you’d hate to just throw it out, the Missouri Department of Conservation offers a few suggestions to repurpose that tree. First, the trees can be used as cover in your yard.
Placing them in their stand near your bird feeder can provide cover for the birds as they are feeding.
You can also decorate the trees with strings of popcorn and cranberries and maybe even add some pine cones that are smeared with peanut butter or suet and then rolled in some birdseed. Put the tree near your bird feeder and watch and enjoy the birds.
Those trees also make good cover along a fenceline. Small animals like rabbits can take cover from the weather and predators.
