Green onions are an easy crop to grow in garden beds or containers. The plants go from seed to harvest in about 50 to 60 days.
What to do with green onions that have gone to seed?
Dig up any onions that produce a flower stem. Once they start to set seed they won’t grow any more, and they don’t store well either. But onions that have bolted are still edible and will taste fine, so dig them up first and eat them, leaving the others to mature in the ground.
What happens to green onions when they flower?

Why did my onions go to seed?

Should onion flowers be removed?
“Growers can cut off the flowers at the top of the stem, or cut the entire stem down near the bulb. Do not cut off the leaves. Removing the flowers will not restart bulb growth.
