I'm finding it hard work. Even a few minutes is just a few minutes of me using a fork down just one row. I suspect I'm not using the fork correctly. I made this film so I could show someone who might be prepared to coach me on how to do it better. I'm fighting the earth rather than working with it. I struggle to sink the fork into the ground. It gets blocked by stones or bricks. A smaller fork won't get under root clusters.
