Here you can see the top spikes on the corn stalks are tasseled out, and the silk is starting to form on my Indian corn. The honey bees are hard at work, even though it is considered wind pollinated. When growing different varieties of open pollinated corn, they must not be in this stage at the same time. For different sweet corn varieties, plant ones which mature 10 days to two weeks apart. You can also delay planting the later type of corn, so they don't get to this stage at the same time. An early sweet corn like Golden Bantam is ready to eat now, while this Indian corn is only tasseled out.
