Alabama has been having early and crazy hot summers in the past few years, excluding this year,( just to keep us on our toes.) I had a friend of a friend who was a popular, local gardener who was known for having corn available before everyone else. I found out that his method was to plant it in January. I wish he was still around so I could ask him about details but I’m going to try it this year and see if I can beat the heat. He told our friend that it might sprout and freeze, sometimes repeatedly, but that it would come right back as soon as the ground gets warm enough.
I realize that it’s not exactly what you asked but it might be a reasonable thing for you to try too. In any case, best of luck! Corn is my absolute favorite crop, especially to bring in warm from the garden and sit down to eat it in just a few minutes, heavenly!
