Rita, I should dig up and take a picture of my soil one of these days and post it. I think my ground finally froze, so I will have to wait until spring to do anything like that, but my soil is not a pretty thing. I think I need to unleash about 5 billion worms in the middle of my yard and let them have at it.
...now THERE's a thought! ....have a crane dig up a giant crater in my yard, put tons of worms in, and cover them up so they can create tunnels all over.
...then again, at that point, I might as well have them lift out all of the soil in my backyard and replace it with good, happy dirt. And by happy dirt, I mean dirt that will make me and all of my plants happy.
