OK so I planted corn in March & about a month or six weeks ago it stopped growing. I posted & every1 said just give it time. Well they never grew over 16" tall so this morning I pulled the stalks & this is what I found. The cobs & kernels on almost all the stalks are perfectly formed. The husks are perfect & they're all wrapped up tight like big ears of corn but they're smaller than a AA battery. If they were so well formed why would they stop growing? Any ideas on what I did wrong? I'd like to avoid this next time.
