I bought some onion plants in a bundle a couple of months ago and planted them out. It has been chilly with some warm spells. But, I noticed maybe 20% of them have tried to send up a seed stalk already. I've just been pinching them off as they appear; does that help to discourage them from going to seed?
I had hoped that these onions would be my full sized end of the season winter onions, but don't know if they'll make it since they seem to want to go to seed so soon. They are a short day onion which should be good for this latitude. At this stage they are not even big enough to use as green onions. Maybe when the weather really warms, they might start growing better?
