JBandRio,
It's good to hear another voice recommending clay as a satisfactory substrate. I don't feel nearly as bad about having clay garden soil as I did before this thread.
Last year I spread a coffee can full of earth worms into the garden soil. Over the following couple of weeks there was a mass exodus of worms. They couldn't stand the inhospitable soil...and decided to abandon their new home. So, after they left, rather than throwing shreded leaves over the garden, I dug a trench and filled it with leaves (see picture) and covered it with garden soil last fall. It was a chance to use my backhoe and get rid of leaves at the same time. It's an attempt to run some organic material deep and make a happy home for the next batch of worm tenants that I may move in. I also like the links in your post!
EagleEye,
Wow. Thanks for the kind words. I knew my FEL operator skills would damage any compost bin I could build. Whereas, a hillside pit just might survive.
