Ultimately, I think gardening speaks to a deep-seated desire to experience the real, the essential, the astonishingly possible. To garden is gradually to give up control, to fall literally to one's knees and come into closer and closer contact with the tremendous and often bewildering beauty of the world. Nothing, you find, is at all what you thought it was. Dirt is not dirt, but a teeming mass of microorganisms that turns death back into life.
