We have had our home garden for the past 3 years. As a chef I always wanted to grow some of the herbs and vegetables that could be used in our catering business. Most of the the items we produce are consumed at home. I get to used quite a few of the herbs like rosemary, thyme, basil in our higher end events.
First thing you must do is learn what growing region you live in. Most local nurseries will be able to give you that information. After figuring out what growing region search your state agriculture colleges and extension offices to determine what varieties of fruit and vegetables grow best in your state. It's always best to start small.
Container gardens are an easy and cost effective way to start a home garden. Most fruits and vegetables do not need a lot a space to grow just the right conditions. Great container crops are tomatoes, green beans, cucumber, and just about ant herb plant. You can get a nice container garden started for for $50.00 or less. I would also buy a good vegetable garden book from your local half price book store.
A few seeds, potting soil, pots and water and before you know it you will have your very own farm to table program.
