The easiest approach to weed control is to prevent weeds from popping up at all in your yard. Impossible? Close to it, yeah. But you can suppress weed growth to a great degree, using:

• Ground covers
• Mulch
• Landscape fabric

Of course, despite your best efforts, weeds will still rear their ugly heads. So consult this pictorial guide to the proper way to weed from Anne Asher, About's Guide to Back and Neck Pain. Use Anne's pictures to determine if you are currently weeding in a body position conducive to keeping your back healthy.
