"Preston writes: Hi I budgeted some of your seeds last year and have great success with them. I didn't end up planting the flint corn last year but want to this year, but also want to plant some sweet corn. I'm worried about cross pollination because I want to save back some of flint corn for seed. Do you think if I wait twenty days after I plant your flint corn it would keep them from mixing? Thank you again, Preston. "
Hello Preston, Corn does easily cross pollinate. If seed saving is your goal, I would not plant flint corn and sweet corn the same year. Happy Gardening, Nan
