Knee-High by the first of July

That's what they say about corn.

Corn wants full sun and doesn't require much love.

For a long harvest, you can plant early and late harvesting corn at the same time. Also you must do succession planting to ensure success! Plant new plants every two weeks for a month or so, that way you will have plants maturing every two weeks in the summer.

As I said earlier, I plant radishes in between, because corn takes a long time and radishes will come up well before they are in the way of the corn.
