Answer: Corn likes warm temperatures for germination, and this spring's cooler than normal temperatures could be slowing things down. Unfortunately, if corn stays in the ground too long without germinating, it can rot. I would give it a bit more time, but be prepared to replant. Your local County Extension agent could advise you about corn germination rates in your specific area. The office is located at 900 Osborn Street in Burlington, 52601, (319) 754-7556.
