Thanks for that info Rick. I could perhaps put some of the clay under the pine tree on the corner of our property. Always fighting the weeds there.
I know that clay does have some good nutrient properties. I do keep some of the clods and lay them on top of the new soil hoping some good leeches out of them. The problem is that I don't plant cover crops as I am just planting flowers for landscaping and I am just down right too impatient to let time do the work. My brother lives down south and has a small farm. He knows all about cover crop for ammending clay.
I only have just under a half acre. The clay comes from deep down when the previous owners had the inground pool dug. The yard slopes and in actuality part of the pool would have been above ground. But they used the material dug out to create a retaining wall and used fabulous boulders to create a dramatic border. I actually want to keep the clay at the front edge just behind the boulders for stability.
In the fall I will cover all the beds with finely shredded leaves.
