Here are 4 rows of beans next to my Flint Indian Corn. If you were planting a food garden, you should be growing 4 or 5 rows of corn for grinding into flour, for each row of dry mature beans. Small grains like Rye, Hulless Oats or Wheat can be offer variety, but if corn cam be grown in your area, it is easier to grow and harvest, and yields better too.
