Here are some tips for re-purposing a de-decorated tree:
Re-decorate the tree with treats for wild birds. Leave the tree in its stand or stand it in a large planter with rocks or sand to steady it. Put it on a deck, porch or patio and decorate it with orange halves, pine cones slathered with peanut butter, suet cakes and small bird feeders.
The tree can also gives shelter to small birds on those cold winter evenings. Once the tree has dried up and turned copper, it makes great kindling for your outdoor fire pit.
Remember, it’s not recommended to use your cut up Christmas tree in the house fireplace, as the pine pitch can become a problem in the chimney long-term.
