With all the rain we had in Missouri, this year corn was not easy to grow. At the grocery store they want $3.99 for 3 ears. That is proof to me I am not alone in losing my yellow corn. But I waited till later i the summer and planted a few kernels of Glass gem. I had 3 ears grow. Today I had to pull them off. Rain and cold were getting to them. But I should have enough to save for seed to plant next year.
This is from the outer shell drying up and the inside decided to try and grow some more. Like when tomatoes crack. It is the added water and growing temp returned for a few days. The plants are confused this year. Too hot or too cold. Up and down. But I have these hanging upside down in the house right now. I think they are dry enough but want to make sure before I remove them from the cob.
