Plant the corn in blocks instead of long rows. This makes it easier for the pollen to reach other corn plants when the wind blows across your crop.
Wait for the corn plants to mature enough for pollination. The top of the plant will flower, and the cobs will produce silk that protrudes about 1 inch out the top of the corn cobs. Pollination occurs when the pollen from the flowers attaches to the silk on the corn cob.
Use a pair of garden shears to cut the male flowering portion, or tassel, off one of the corn stalks. Use it to dust the silks on the ears of corn on adjacent plants until all the pollen on the tassel is gone. Repeat the cutting and dusting of the tassels until all the ears are pollinated.
