What soil temperature does corn need to germinate?
Corn requires 50°F minimum soil temperature at 2-inch depth for reliable germination, with optimal germination at 60-85°F. Below 50°F, germination is slow and uneven; below 45°F, seed often rots before emerging. Sustained 50°F+ soil for several days plus a stable forecast triggers planting decisions.
