What's organic gardening, exactly? Growing organically means eliminating synthetic chemicals (commonly used for pest control and soil nutrition), as well as encouraging biological diversity by planting a mix of species and rotating plants over time.
Note that if you plan to sell your produce, you must follow specific rules as defined by federal law in order to claim that the produce is organic. The term "organic" is defined by the National Organic Standards; details can be found here.
There's nothing like picking your own vegetables and eating them straight from the garden. Start an organic garden in your own backyard with tips from Ann Thrupp, director of sustainability at Fetzer Vineyards in California.
