You'll find that Paul also has goats and chickens for garden purposes, but I am against having (owning/using) animals, so I am not advocating these methods. I also disagree with his archaic language of a "Creator". It seems Paul confuses Natural phenomenon with an Intelligent Creator; and in the video below you'll get a mouthful of religious philosophy; but all that can be ignored, because he has a great personality and he himself is an intelligent man with a beautiful garden and Fruit Orchard.
Paul has an astounding production of food and all of his food grows faster, more abundant than conventional food. I was truly amazed by the sight of his gardens. This man has great wisdom, and I recommend watching the video below to full extent. He shows you how to avoid tilling, avoid weeding, and dispels myths about gardening saying "Everything we know about gardening is a lie".
