Think of summer vegetables, and sweet corn usually comes to mind. Corn was a main source of food for early American people and was one of the few “native” vegetables to spread throughout the world. Sweet corn is rich in carbohydrates and sugars and contains vitamins A, B, and C, minerals and protein. It is an excellent vegetable for freezing or canning, extending this summer treat for year-round use. Sweet corn is not well adapted to a small garden area, and corn planted too close will produce poorly. Consider whether you want to invest the space to grow sweet corn if your garden area is limited.
