A lot of Missouri towns turn their trees into mulch. It’s laid at the bottom of living trees to hold in moisture and keep lawnmowers from cutting too close to the tree. In the Lake of the Ozarks people sink whole Christmas trees for fish to use as cover, and for young fish to use as hideouts. Rural Christmas tree owners can drag them to the edge of a field to attract small game, or throw them in a gully to slow soil erosion.
