Tomatoes are the most widely grown vegetable in gardens across the United States. Tomatoes are relatively easy to grow, can produce a multitude of fruit, and can be used to make many different types of food. Growing tomatoes organically is very easy. Make sure that you choose a sunny spot for your new plants and that you prepare the soil with organic matter before you plant.
You should water and fertilize your new tomato plants about every week until they start to produce fruit. Once fruit production has started, you should continue to water your tomato plants throughout the growth process and even after the first harvest, as they will continue to produce for some time and continual watering will prevent the plants from going into shock.
Other vegetables can be grown organically according to much the same guidelines. Some vegetables such as squash, cucumbers, and even beans, require little or no maintenance besides regular fertilization and pest control.From My Garden
