I guess I should have taken the hint when the cutworms took down every one of my corn seedlings in the spring, but I persisted and replanted with cutworm collars.
The corn patch was uneventful until mid July when the ears began to form and then the squirrels arrived. This is my third year growing a garden here and I've never had the squirrels problems I've had this year. I'm afraid they have officially discovered my garden and have permanently moved in. Note the gap in the corn bed. There were corn stalks there, but the squirrels have toppled them and I even caught a squirrel running away with the entire corn stalk!
This is what the corn looks like now:
My total corn harvest stands at zero.. sigh. I planted a second patch of corn, so perhaps I can beat the squirrels to a few ears in the fall. In the meantime, I am dreaming of a squirrel proof garden like this image I found here.
