I understand that sweetcorn has different growing periods to age of maturity depending on what variety of corn you plant. My question is if I plant 60 day and 75 day corn at the same time, does that give me the proper growing time between germination and pollination for the two different kinds of corn so that there will not be cross pollination, or is it possible the 75 day corn has a shorter germination to pollination time period and therefor cross pollination would be a problem. My example would be: if I plant a 65 day corn and plant popcorn on the same day would that be a problem? ( the popcorn is 105 days to maturity, but I don't know how many days to pollination.
