Onion tops dying prematurely?
I planted onion sets back around the end of May. The tops of them started to grow. I thought they were growing good, but after seeing pictures of other peoples onions I realized mine were nothing to look at. Anyway, The onion began to grow to around 1 1/2" in size. Then the top died back and it doesn't look like it is growing any more. This is a big variety. I can't remember the exact name but it was a big, sweet variety so I know it should have grown bigger.
Is this onion all done or can I do something to keep it growing?
