j_kraut said:Cool, sounds like start indoors is the way to go. I am looking a small pots and also the toilet paper roll methods. In all, i will do about half my area with started indoors (prob next week, i'm in Minnesota), and the other half i'll sew right in ground in early May.
If you plant before the ground is warm, the corn will probably rot in the ground.
Transplanting in cold weather you corn will probably yield poorly, and just sit there deciding whether to live or die.
This is from experience.
Key Points
Deciding to plant when soil temperatures and forecasted temperatures are cold must be made on a case-by-case basis and opinions may vary widely.
Continuing to plant through cooler temperatures can keep planting operations moving; however, when planting into cold soil, corn kernels will be slow to germinate, plants will be slow to emerge, and the risk of seedling death is elevated.
Once planted, corn seeds need a two-day (48-hour) window when the soil temperature at planting depth does not drop below 50°F.
Corn requires a soil temperature of 50° F to germinate. ... When planting into cold soils or a forecast of cold temperatures, there can be a risk of imbibitional chilling injury which may delay emergence, cause an irregularity in growth and expansion of the coleoptiles, or cause complete failure of emergence

This is the cold extreme, at best.
You are in Minn, where I am and in the past few years, farmer have had to replant a lot of corn fields due to cold failure.
This is why some recently have planted at the last crop insurance date so if it still failed they had insurance.
