|I wish to grow an early -season corn, and a mid season corn. I've picked "early sunglow" (63 days - sh2) as the early
variety and "breeders choice yellow (73 days -sh) as the
mid-season variety. I don't have the space to keep them apart. Will they cross-pollinate?
|Sugar enhanced varieties should be isolated from non-Sh types of corn to prevent cross-pollination. Both the varieties you've chosen are sugar-enhanced, so there shouldn't be a problem with them growing near one another. If possible, keep each block of corn 3' apart from other varieties. Corn needs lots of sunshine and warm soil temperatures so wait to sow seeds until two weeks after your usual last frost date.|
