Is it OK to let onions flower?

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 grow from seeds?

Growing onions from seed is easy, and allows you to choose the exact varieties you want to grow! Purchasing started seedlings or sets is also a great option, and will give you a quicker start than seed. Onion seedlings are like small green onions, recently started from seed (within the last couple months).

What are onion seeds?

Onion seeds are onions that have not started to grow. Onion seeds are considerably less expensive than sets and you will find a much larger variety. However, they need to be started very early indoors so if you’re late getting started or you prefer direct-planting outdoors, you’ll need to look into onion sets instead.

What are the bulbs on top of onions?

At the the top of the stalk, a cluster of bulblets will begin to grow. These bulblets are also known as “bulbils” or “sets.” We will refer to them as “topsets” throughout this website because they literally are onion sets growing at the top of the plant.

What do bolted onions look like?

How to trim onion seedlings?

Trimming onion seedlings 3. Clip off seed husks Soon after germination occurs, my indoor-grown onion seedlings often do a poor job of pulling away from the seed. The stuck seedling looks like a little green loop. Eventually the smaller end pulls out of the soil, weighted down by the black remains of the seed husk.

How to grow onions from seed?

Eventually the onion seedlings stay outdoors 24/7, provided temperatures are well above 46°F (8° C) at night. Consistent exposure to temperatures below 50°F (10°C) for more than 10 days can cause onions to bolt rather than producing big bulbs. 9. Band composted fertilizer in the planting trench

How long can you keep onion seeds before planting?

Onion seeds can be kept for two years in a cool, dry place such as a properly monitored seed storage box, but fresh first-year onion seeds germinate best. Germination rates fall as the seeds age, and though I have had three-year-old onion seeds that sprouted well, germination is always highest with fresh seeds.

How do you keep onions from falling over when growing?

I keep the lights on my onions for 12 hours a day, and position them within 1 inch (2.5 cm) of the bulbs. Every day or so I trim the onions back to about 3 inches (7-8 cm) tall, which keeps them from falling over.
