I'm both sorry to hear about the onion problems some of you hav had but at the same time a littlecomforted that I'm not alone.
just over a month ago i had 3 beds of lovely looking onions from sets. 3 weeks ago I had immature bulbs with short brown stems attached. the entire crop were uniformly affected. I lifted them & laid them to dry on the green house staging. Some of the stems were so wet they oozed water as I gripped them to pull up the bulb.
the ba news is that a number of them have already gone a bit soft & ar unuseable.
I still hope to be able to dry & stoe some of them, but it's apretty depressing harvest.
