Trimming while seedlings are young is better for root and bulb formation. Cutting off the top green growth forces more of the plant’s energy into the root system and also the forming bulb just above it (onions bulbs are actually the base of the leaf system with roots growing from the base of the bulb).
When should you top onions?
Fold or bend onion tops when they begin to turn yellow and fall over on their own. This occurs when the onions are large and the tops are heavy. Once you’ve folded the top of the onions, leave the onions in the ground for several days. Withhold water during this final ripening period.
Should I bend my onion tops over?
They contend that folding, breaking, or stepping on the tops of your onions doesn’t actually increase the size of their bulbs.

Do you cut the bottom or top of an onion?
Make lengthwise cuts into the onion, from root end to stem end, with the knife tip almost all the way to the root end (but not cutting through the root end). Cut at an angle as you go around the onion, with the blade aimed toward the center of the onion.
Do you break onion tops while growing?
You can cut off some of the green leaves to cook with while the onions are still growing, but never take the entire top, or the bulb will stop forming. Instead you can cut the top few inches, or take 1-2 leaves at a time.
What month do you lift onions?
Autumn-planted sets are ready to harvest by early to mid-summer, while spring-sown or spring-planted onions are ready in late summer to early autumn.
Why do you top onions?

Should I stop onions flowering?
Unless you wish to save the seeds for use next season, cut the flowers off any onions that have bolted. This won’t reverse the bolting process but it does stop the bulb from dividing. Bolted onions are perfectly edible and although they’ll last for a month or so in the ground, they won’t store.
Should I cut off onion flowers?
As soon as you see an onion has flower buds, snip the buds to prevent the bulb from splitting, then harvest and eat those onions first, the sooner the better. Onions that have bolted don’t store well. Onion bolting is a problem for even professional growers.
Why are my onion tops falling over?
As maturation proceeds, necks soften and the weight of the leaves causes the tops to fall over. “Tops down” is the physiological response that results from compounds shuttled from the onion’s leaves to its scales; consequently, the bulb swells and the tops dry down.
Can you do anything with tops of onions?
If you find an onion with the long greens still attached (mostly in spring), don’t throw those greens away! They have a lovely mild onion flavor and you can use them just as you would use a scallion. Chop them up and mix them with Neufchâtel cream cheese to spread on a cracker or add them to fresh salsa.
Should you hill up onions?
Weeding – Onions compete poorly with weeds because of shallow root systems. Hand-pulling weeds or shallow cultivation is necessary; do not hill up the soil on onions. Maintain a weed-free bed and apply an organic mulch to maintain soil moisture.
How do I stop my onions from being so strong?
You can get rid of the strong taste by soaking sliced onions in ice water for 20 to 30 minutes or by sprinkling them with an acid such as vinegar. Onions soaked in ice water will get very crisp while those sprinkled with vinegar will soften a bit, but they will lose the strong taste and become sweeter.
Which end not to cut off from an onion?
Method for Slicing an Onion from Stem to Root

An easy way to peel an onion is to top and tail it, then cut it in half from top to bottom.
Why is my onion growing a bulb on top?
Seeing flower stalks forming on your growing onions can be disheartening. A bulb on the top center stalk of your onion means it has begun the process of flowering and making seeds. This is called “bolting,” which is terrible news for onion growers.
How many times can you regrow an onion?
And as long as you leave the bulbs planted and water them regularly, they’ll continue to regrow more onions. Expect to get three to four harvests from your bulbs before you need to plant new ones.
Can you stop onion bolting?
To stop them bolting, keep their conditions as constant as possible. Cover them with horticultural fleece if a cold snap is expected in spring, and keep them well-watered in any hot weather. And if you see a flower head forming, snip it off immediately before it blooms. Dig up any onions that produce a flower stem.
How long can you leave onions in the ground?
When you notice the leaves on the first few plants start to fall over, stop watering and leave the onions in the ground for 7 to 14 days (depending on how dry or humid your climate is) to allow them to finish maturing.
