My popcorn is looking good. Green and thick. My neighbor commented that she had never seen corn planted so closely. I suppose I plant everything a bit close. I think in a small bed it works because there is space at the edges. This corn is about 9 inches apart in the rows (8 or 9 plants in a 6 ft wide bed) and rows are 12 inches apart.
No sign of tassels or ears yet. When I do get ears, I will spray their silks with spinosad (Captain Jack's Deadbug Spray) so corn ear worms don't get in it.
