So, I have no car, but I still have a driveway. It is is not paved and gets full sun, the perfect place for a garden. Since it has several feet of imbeded gravel, preventing any hope of taking a shovel to it, I thought it would be tre cool -and a shade- ironic to convert the driveway into a garden using old tires filled with soil and organic compost. With everything els going on in my life I am off to a slow start with this project, but I have been ferrying abandoned tires home as I find them, piecemeal, and hope to have it all set up by Spring. For now I have a nice little crop of spinach in the first tire.
