Onions, garlic, and leeks are good crops to grow for the farmers market because you can sell them at different stages of growth, their harvest dates are flexible, and you can store them. You can also make products such as garlic braids to add value to your crop. Onions and garlic are basic cooking ingredients and are healthy to eat. If you grow different types of onions such as sweet onions, fall green onions, and storage onions, you can harvest from early spring through late fall.
