You can save money and have some fun by saving seeds from garden vegetables and flowers to grow again next year. While it is easy to do, to succeed you need to know what kinds of seeds to save, when and how to save them and, in most cases, how to prepare them for storage before you grow them. Some of the easiest seeds to save and grow, among vegetables and herbs, are parsley, coriander, beans, kale, arugula, lettuce, and non-hybrid tomatoes and peppers.
