I stopped by the City Recycling Center today and they had free mulch for anyone w/ containers and shovels. I grabbed 4 18 gallons containers worth.

Before I use this stuff I will have to separate out any trash, large pieces of wood and treated wood.

This stuff is mostly shredded wood from tree cuttings. When I was getting the mulch I took stuff from the warm sections toward the bottom and middle where there was some composted material. Would this stuff be good/safe to use as a ground cover for some of the flower beds and put what is not needed in the compost bins?
