There used to be a place in Hendersonville or Gallatin where we would go and get free mulch. Might be the same sort of deal.

Do you make your own and just need more? if you don't do your own composting, it's easy. Just save your veggie scraps (uncooked), grass clippings, dead leaves & such - add a little year old manure and wait. see my blog post about a good container below

Here is a link that might be useful: compost bin

If you're not too far from Murfreesboro, you can get free Mulch at the city's facility on Florence Road (Monday thru Friday).
