When should sweet corn be planted?

Sweet corn should be planted as early in the spring as possible. Whenever soil temperatures approach 68º F, seed should be planted 1 inch deep. Waiting for warmer soil temperatures will increase the chances for a better stand, but planting as early as possible will pay dividends at the end of the growing seasons. Early planted sweet corn will mature before the corn ear worm population becomes very large. Late planted sweet corn will have serious problems with corn ear worm infestations. Supersweet (sh-2) types do not emerge as well as the other types in cold soil.
