I've heard a few variations on this.. was curious if anyone had any
thoughts..

I've heard its ok to plant the white corn and the bicolor at the same
time, as long as you aren't saving seeds.. i've also heard to not do
it as they will cross pollinate and result in tough kernels.

Or.. i've heard that its ok, as long as you say, plant one one week
then wait a few weeks and plant the other variety...

Any thoughts on this? I dont have 100 feet to separate the varieties
either.. more like only a few feet

Thanks
