If you're just getting into organic gardening, growing herbs is a great way to start. Most herbs naturally deter pests and diseases, making them perfect for new organic gardeners.
Two great resources for getting into growing organic herbs are a new book by Graham Clarke and About.com's own Herb Gardens Guide.
Graham Clarke's The Organic Herb Gardener is full of great information about not only herb gardening, but general organic gardening as well. If you want to know which herbs will grow best in your zone, or how to propagate certain herbs, this is a useful book to have at your fingertips. You can read my full review of The Organic Herb Gardener here.
And I'd be remiss if I didn't recommend our awesome Guide to Herb Gardens, Amy Jeanroy. If you're just getting into herb gardening, check out these great articles by Amy:
