How to Store Sweet Corn Seed for the Following Year

While storing seed from the previous year's crop delights any independent-minded gardener, saving and storing corn seed presents special challenges. Corn is notorious for cross-pollinating with other varieties growing nearby. On the other hand, an undesirable condition called "inbreeding depression" occurs while storing seed from only a few ears. Remember that seed saving only works with nonhybrid heirloom corn. But the actual saving and storing process for corn seed is quite manageable.

Instructions

    • 1

      Pick out the ears you plan to use for seed while the stalks are still growing. If pests are a problem, put paper bags over the ears. Choose stalks that look vigorous with ears that seem well developed.

    • 2

      Wait about four to six weeks after picking your "eating corn" before you harvest the seed corn. Make sure the harvest takes place before the first frost.

    • 3

      Harvest the ears and remove the paper bags.

    • 4

      Strip the corn down to the cob's base but do not remove the husks.

    • 5

      Hang the ears in a place free of drafts, moisture and pests. Several ears can be bundled or twisted together by their husks.

    • 6

      Keep checking until the corn is completely dried out; the process usually takes at least two months. A properly dried kernel of sweet corn will be quite wrinkled.

    • 7

      To remove the seed, hold each ear over a bowl, twist with both hands, and shell the corn.

    • 8

      Pick through the seeds to weed out any that aren't the same color as the others, or that don't look properly wrinkled.

    • 9

      Store the seed in paper bags in a cool place until the next planting season. The refrigerator's crisper drawer is ideal. Alternatively, store the seed in glass or metal canisters.
