One of the benefits of mulching a garden is weed control
MULCH ELIMINATES WEEDS
Paul Gautschi has popularized wood chip gardening, a no-till gardening technique, that helps weed control. Not only does mulch reduce the amount of weed seeds that germinate, it also makes weeding easier. The soil in a mulched garden is less compact than a conventional garden. This soft, fluffy, aerated soil allows weeds to be easily removed with all of their roots attached.
