In the interest of being green and being efficient. I'm going to try and add a weekly update to this site where I find free stuff that is green.
The first free item I've found is Mulch, provided by Los Angeles Bureau of Sanitation. Specific Information in this PDF. Just drive up to one of six locations, scoop up some compost, go home and use as potting soil or ground cover. Take as little or as much as you want.
