Onion set question
Hope someone can help me. I planted these sweet onion (large round ones, when mature) sets in October 2004. It is very rainy here in the winter and gets down to the 30's, with daily highs in the 50's generally. They sprouted but were very slow-growing. We've still got them growing, but .....
The plants look pretty healthy right now, but are not really bulbing -- if I dig carefully around one, the base looks something like a small leek but not a sweet onion. Each onion plant has formed a big thick flower stalk with an unopened flower bud on top.
Are these onions toast ? Should I snip off the flower stalk ? Will they grow to maturity and give us some nice round onions ? What should we do ? Thanks in advance.
