Nightcrawlers are notorious for pulling young onion plants and pulling the tips into the ground. Drying onion plants are one of their favorite foods.
What causes onion sets to bolt?
Bolting happens when the plant feels stressed. It reacts by rushing to reproduce by flowering and setting seed before it’s fully grown. It’s easy to recognise a bolting onion. The plant shoots up a solid stem and a flower pod appears at the top.
Why are my onions popping out of the ground?
Bulbs Popping Out Of Ground
If your onion bulbs are popping out of the ground, that’s actually a good sign that they’re growing. As they mature, they naturally begin to pop up, and the outer leaves turn papery. Avoid covering them up as they do this to reduce the chance of rotting.
What happens if onion sets are planted too deep?
The deeper you plant them, the harder it is for the bulb to expand.
Should I cover my onion sets?
You may need to cover the sets with horticultural fleece, to stop birds from pulling them up. Drooping yellow foliage is the first sign of onion fly larvae, but by then they’ll already be eating their way through the bulb by the time you notice the damage.
How do I stop my onions from 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.
Can onions be overwatered?
When watering your onions, there is a fine line that must not be crossed when it comes to the amount of water your onions need. Onion plants require adequate water to produce high yields, but it doesn’t take much over watering for your onions to become diseased and rot in the ground.
Why are my onions not forming bulbs?
Make sure you’re growing bulbing, not bunching onions. Bunching onions will grow into scallions, and they will never form large bulbs. Shallots will also stay much smaller than yellow, red or sweet onions. Planting onions too late usually results in disappointingly small bulbs.
When should you top your onions?
When to Trim Onion Starts. Trim onions when they are about 6 inches tall or when they are bending and getting tangled.
Should my onions be covered with dirt?
Set plants 1 inch deep, so that their roots are well covered with soil but the top of the plant’s neck is not buried too deeply. You don’t want the part of the neck where the leaves grow away from the clear sheath to collect soil or water down between the young leaves, or they can rot.
Do onion sets go soft when growing?
Re: Onion sets soft
Yes – the bulb is the energy store to get the roots and shoots started and doesn’t fill out again until later in the season.
Why do my onions have thick necks?
Onion neck rot is a disease of onions and shallots caused by the fungus Botrytis allii. Plants infected by the fungus usually appear perfectly healthy whilst the crop is growing. Symptoms are not usually seen on the bulbs until they have been in store for several weeks.
How long will onion sets last?
Can you store onion sets in the fridge? They will last for as many as seven months when stored at a temperature of 32 degrees Fahrenheit; just make sure that there isn’t moisture in the refrigerator that can cause the sets to rot.
Can you grow onions in the same place every year?
Don’t plant them in the same location year after year, as this can encourage the spread of diseases that affect the crop. Learn more about crop rotation. Select a location with full sun, where your onions won’t be shaded by other plants. The more energy they can get from the sunlight, the larger their bulbs can grow.
How do you take care of onion sets?
Caring for onions
- Keep the plot well weeded. Hoeing between rows risks damaging foliage and bulb tips, so weed by hand where possible.
- Water regularly in dry periods.
- Remove any flowerspikes as soon as they appear.
- Stop watering once the leaves start yellowing – this means that the bulbs are starting to swell.

When an onion flowers, often referred to as bolting, the bulbs are still edible, but quality of the bulbs as an edible food crop diminishes. The overall size shrinks, flavor diminishes and the onions are harder to store. If the onions flower, dig up the bulbs and eat them right away.
Do onions self seed?
As mentioned, the Alliums such as onions, leeks, and scallions are examples of self-seeding vegetables. These biennials overwinter and in the spring flower and produce seeds. You can either collect them or allow the plants to re-sow where they are. Carrots and beets are other biennials that self-sow.
What are the bulbs on top of onions?
Bulbs atop your onions means they’ve launched into the process of flowering and setting seed. If you purposely didn’t harvest last year and overwintered them instead, this is normal. If this is their first growing season, that flower stalk is premature. This is called bolting.
What causes bolting in plants?
Plants bolt as a response to certain stressful situations, which prompt them to begin the reproduction process. The most common stressful situations that cause bolting are increased day length, high soil temperatures, and root stress.
