With corn the more the merrier (that is, better pollination). The smallest I would go is 4'x4' grid of plants 1' apart, that gives you 25 plants. Even then I'd help the pollination by shaking the tastles a couple times a day while the corn is silking. Some people have had success growing corn in containers, but I haven't tried it.

Also for the first time grower of corn, I'd recommend varieties of the short and early type like Quickie or Early Sunglow. Then if you have good results, next year move up to taller later varieties like Silver Queen or Kandy Korn.

Please inform your son that each corn plant only produces two or three ears....at the best. The above suggestion is a great one.
