Hey all you midwesterners, ever grow in cornfields? Most farmers nowadays use roundup corn. So you must wait for there last spray, and just stick them in the row, usually sometime in early june, the plants should be maybe 2.5 ft tall or so. They will fertilize them for you, and they get full sun. It does have to be a reasonably early matureing variety, and you have to watch for when they start picking in that area. Last of sept. all the way till middle of oct. depending on the farmer and the field. It sure worked last year for one of my buddies.
