Hi Suzi! I've been an organic gardener since I was a child. I had two wonderful grandmother's who both gardened, and I was always around to help. All you really need is a patch of soil--the size depends on how much you are growing. Dig down at least 12 inches, mix in several bags of manure, compost, and peat moss. These agents enrich the soil, help with drainage, and attract the "good" insects. Follow the instructions for planting and watering on your seed packets, then sit back and watch your garden grow! If you have animals, it is important to make sure you protect your garden. Animals are notorious for thinking of the garden as a bathroom...I don't need to tell you how unsanitary that is! Also, if you are planting a food crop, it is important not to use "miracle grow" or other common fertilizers found in the garden section of Wal-Mart. After you enrich your soil with the amendments I listed above, there will be no need to fertilize again. If you do want to add chemicals, visit the local farm coop or a true greenhouse for products.
