I'm still puzzled why my back garden corn failed while the corn planted on the allotment (same variety, tougher conditions - no water and a thin sandy soil) did OK .
I had put it down to lack of water but I always think of corn growing in hot, dry conditions.
Some time ago Hanna wrote about growth inhibitors in the seed husks of sunflowers. Clearing the corn yesterday it struck me that the difference between the back garden corn and the allotment was the former was next to the sunflower bed.
Could this be why it failed?
But the time the corn was setting, the sunflowers wouldn't have been producing seed or husks. I wonder if they secrete the growth inhibitor any other way?
