A common question I hear from clients is “What should I grow?” The answer? That depends. What would you eat?
Make a list of vegetables, fruits, and herbs you and your family or roommates eat regularly. Which items on the list are most important for you to grow yourself? These plants (or at least some of them) are what you want to begin with. You can always add more later as you learn more about gardening. Eventually you may want to add plants that you have never eaten but have always wanted to try.
Make a list of what you grew including how much, what variety, and when you planted. That way next garden season you can decide whether to plant the same variety and amount.
