"Dillo dirt" is a fine product of our local industry--Austin's refined sewer sludge and mulch combined together into a rich, dark compost. Great for refreshing lawns. Good stuff, reasonably inexpensive, and how very green of the city of Austin to turn sewer sludge into gardening material.
After devastating a large chunk of my lawn by digging holes, tromping all around, and getting clay all over the grass, I upended a few bags of Dillo Dirt I had around the area, by way of apology to the grass.
Out of one of them fell a five-pound wedge of concrete.
Beyond the very basic question of how and why, one must ask--WHAT do Austinites EAT?!?
