The best way to dispose of a Christmas tree is to recycle it. Many cities have curbside recycling programs that will pick up your tree after the holidays. You can also take your tree to a local recycling facility or transfer station. It's important to remove all decorations and tinsel before recycling your tree. Some organizations will also collect trees and use them for habitat restoration or shoreline protection. Whatever you do, please do not burn your tree or put it in the trash.
