To store away your Christmas tree, you can begin by removing all of the ornaments and decorations. Then, you can disassemble the tree and put it back into its original box or a storage bag. Make sure to label the box or bag with the year, so you know which tree is which when it's time to set it back up again. Finally, place the box or bag in a cool, dry place where it will be safe and protected until next year's holiday season.
