Since we began gardening several years ago—when we moved into our first house—we have grown our vegetables in raised beds. This has always been primarily a practical decision. Had we topsoil to till, I would gladly till it, amend it, and leave it where it lies. But in our present home we had to cart in, wheelbarrowful by wheelbarrowful, two pickup truckloads of soil and compost just to get started. There was no point digging it into solid clay; far better for our backs and our crops simply to dump it on top and build a box around it to keep it in place.
