My fiel corn that was started from the seeds that Ken sent me are about 6 to 7 foot tall and are tassleing out but there are no ears on the stalks. Can anyone tell me why? I am thinking that maybe I just don't have enough nutritional fertilizer in the ground. I broke up new ground and didn't get a chance to add anything to the ground. I was kind of hoping that since there hadn't been a garden there in about 20 years then there should be plenty of nutrition for the corn to grow. I guess maybe I'm wrong.
