Harvest corn: Allow corn for seed to remain on stalk and dry after corn for eating has been harvested. Leave on the stalk for an additional 4-6 weeks. Pick when the husks turn brown. However, if there is a hard frost coming, harvest the seed corn in advance.
Dry corn: Pull back the husks so that kernels are exposed and use a string to secure the husks in this position. Hang cobs in a dry area and allow to dry for three months.
Test dryness: After three months, take down the corn. Test for dryness by removing one kernel, placing it on a hard surface and hitting it with a hammer. If the kernel shatters, it is dry. If not, the ear needs to hang longer. Test again in three weeks.
Harvest seeds: Remove kernels from the cob by rubbing two cobs against each other or twisting an ear in your hands so that kernels pop off. Do this over a large back or window screen to catch kernels. Remove any debris.
Label and Store: Transfer to a sealed container and store in a cool area. Kernels should remain viable for 2-3 years.
Plant seeds in full sun and nutritious soil with a neutral pH. Plant outdoors two weeks after the last spring frost.
The most important concerns for people growing corn, especially those interested in saving seed, is ensuring sufficient isolation and a large enough planting to maintain genetic diversity. Isolation distance depends on local conditions - namely, wind patterns, windbreak, and the crops grown by neighboring growers. However, generally, corn needs 1/2 mile of isolation to avoid cross-pollination. Ensure that the size of your 'parent' planting is sufficient in order to avoid weakening the population by narrowing the genetic base too much. Grow at least 200 corn plants to avoid this problem, and be sure to collect seeds from at least 100.
