Answer: Corn should be ready to harvest about three weeks after the corn silks appear. You can check for ripeness by pulling back part of the husk and piercing a kernal with your thumbnail. If a milky juice spurts out, it's ready. If not, put the husk back and check again in a few days. It's getting a little late for harvest, even in your region, and it's possible you've waited too long to harvest. If the silks on your corn are completely dry, or if the outer covering on the husk is yellow or faded-green, the ears are past their prime.
