Can sweet corn be planted near popcorn in the garden?
Sweet corn should be isolated from popcorn and field corn to prevent cross-pollination. The quality of the sweet corn will be lowered if it’s cross-pollinated by other types of corn. For example, sweet corn pollinated by popcorn will be tough and starchy. Cross-pollination can be prevented by planting sweet corn 250 feet away from other types of corn. Cross-pollination can also be avoided by planting the various types so they mature (tassel) at different times and by avoiding prevailing winds when planting.
