Corn/Maize IntroductionCultivation InstructionsSeed Saving Instructions
Domesticated in Mexico by 6,700 B.C., corn is a staple food and has many ritual uses. Mature kernels of dent corn are dented due to flour heart and flint sides. Used for elote (roasted), tamales, tortillas, corn beer and animal feed.In early spring or with summer rains, plant seeds 1" deep. If rows, plant seeds 12" apart; or 3-4 seeds 18" apart in basins (for arid regions) or hills. Needs rich soil & moisture. Heat, aridity & high winds can all reduce pollination.An annual, corn is wind-pollinated, and all varieties will cross. Hand-pollination (with bagging) or staggered planting times is necessary to keep seeds pure if multiple varieties are grown. Allow ears to mature and dry on the plant.
