Good research V!
My garlic that is behaving "badly" perhaps was planted too early - by a few weeks - but we had a warm and horribly dry winter.
And these were cloves saved from my previous grows, so I am attributing this to a lack of vernalization (sp). I did not over fertilize and did not over water. Normally, my leaves die back to nothing. This year, they grew tall as ever.
Makes me wonder how to grow garlic during global warming...
