The last sweet corn I planted said either 250 feet or yards; I forget
which. Not many gardeners have that much space, so you just have to
do what you can. If you have two varieties that are likely to
pollinate at the same time, plant them at opposite ends of your garden
and hope it's not real windy when they pollinate. If you have
varieties with very different pollination times, you can plant them
close together and not have to worry about cross-pollination.


I think only one type of supersweet corn has to be isolated from other
varieties -- I think they are called "sh2". You can plant normal sweet
corn and "sugary enhanced" varieties together without ruining them.

Do not plant popcorn or "Indian corn" near your sweet corn.

I'm gonna plant corn today; Golden Bantam and Silver Queen, right next
to each other. I don't know if Silver Queen will produce this far
north, but it's Wife's favorite variety so I'm gonna try it.

Best regards,
