December 26, 2018 to January 18, 2019 -- Recycle your live Christmas Tree for "FREE". Trees will be shredded at the Darke County Parks Praire Preserve on St. Rt. 502 just outside of Greenville. The shredded tree mulch will be used on nature trails throughout the park district. A huge THANK YOU to the Darke County Parks Maintenance Staff for shredding our trees for us!!
