If you got a natural Christmas tree this holiday season, whether from a tree lot somewhere in town or you cut it down yourself, local governments are opening tree recycling centers to help dispose of it as the holiday season comes to a close.

“Treecycling” serves multiple purposes. They are often turned into mulch, which can be used in parks and backyards to block weeds, keep soil healthy, and prevent frost heave. Several city recycling programs offer mulch at either a low cost or free of charge to those who bring in their trees.

To make these programs work, be sure you remove all decorations, including those hard-to-spot final ornaments and any last bits of tinsel, and pull out any nails.

And to be clear — these programs are for live Christmas trees only. Artificial trees that are still in good shape can be donated to your local thrift store.
