My ears of corn have only spotty kernel growth. I am wondering why.
This happens due to poor pollination. Corn needs to be planted in a certain pattern (side by side rows) and conditions need to be right at pollination time (not too hot or too rainy) for best pollination. If the pollination is poor, you will get spotty kernel growth.
In the future, just to make sure that you get the best production, you may want to hand pollinate your corn. This article will help:
