Q&A for How to Plant Sprouted Onions

To check the onion, stick your finger in the soil and run your finger around the bulb. Then, harvest it when it's the size you want.

If you plant it in a pot of soil and keep it watered, trim the shoots as they appear, and you can delay buying more onions for weeks.

In my experience, the onion bulb will produce more sprouts until it dries up. Keeping it in water can help maximize the number of sprouts.

Yes, you can plant the sprouting bulb. It will need time and regular watering to develop roots below the bulb, and then you will have a fully functioning onion plant.

In my experience in Canada, onions can survive the winter and continue growing for several seasons without assistance.

Growing onions is easy. As long as you water the bulb often (daily is ideal), you will get green shoots. If the root system develops, the plant can mature and produce bulb clusters that can grow new plants. In my experience, onions can even survive winter in Canada and come back to life every spring.

The bulb grows below the soil, while green shoots grow above. The mature plant may produce a flowering stem with a cluster of new bulbs on top, which can eventually fall and plant themselves to form new onions.

The greens are delicious, and you can use them to add flavor when frying other vegetables.

All colors of onions are generally easy to grow. The red color is due to extra carotene production, but the taste remains similar to other onions, with some variations being hotter. In my experience, yellow and white onions survive Canadian winters and return each spring, thriving with enough water.

It depends on how long the onion stays planted. If allowed to mature, one or more green shoots can produce a cluster of bulbs on top, multiplying the number of onion plants.

If you mean the flowering head, it's best to leave it until it matures. The stem will be too hard to eat, but the plant will produce next year's onion bulbs if given time and water.

If you plant a whole bulb, you will grow a single onion plant with multiple shoots. One or more of these shoots can mature into a cluster of new bulbs. You can harvest the shoots for cooking before they become tough.

You can place the sprouts on a wet tissue or paper towel to keep them stationary. Using shallow water may also help, but be sure to monitor it so it doesn't dry up quickly.

The green onion shoots are tasty and can be harvested multiple times per season from each plant.

In my experience, onions survive winters in Canada, so anything above freezing will be okay. The important thing is to make sure they get enough water once the spring rains are gone.

You should remove the entire shoot before it turns completely brown. Alternatively, you can plant it, keep it watered, and harvest the shoots for weeks.

The skin indicates it is mature. Drying helps ensure no mold will grow and destroy it.

Onion bulbs will often grow multiple green shoots, but they remain a single plant. To get more plants, allow the onion to mature and produce a cluster of new bulbs at the top of a shoot; each new bulb can grow into a new plant.

If you mean the green shoots, they can grow up to a foot long. Some chefs will tie them into a knot for boiling. If you mean bulb onions, you might cut them into quarters for a chunky stew. If the bulb is very small, like a shallot, you can avoid cutting. To minimize tears while cutting, do it under water or wear airtight glasses, such as swimming goggles.

Onions thrive in both sun and water; however, they will grow greener with sunlight. Just ensure the water doesn't evaporate completely under the sun's heat.

Even one inch of roots is enough to plant them in soil. Watering is essential, so make sure to water daily to prevent the onions from drying out.

If you let a sprouted onion grow, it will continue to develop, and you can trim the green shoots for cooking as needed.

In my experience, onions can be grown indoors during the winter. You should place them in pots, provide 24-hour light, and water them often, using trays to catch excess water.

Yes, that is possible, but you will also need to wash the rotted area, even when you cut it away, because germs could infest the rest of the onion and turn that rotten, too. Also, check if any other areas of the onion look slightly off.

Yes, the green blades are edible and delicious. Try to harvest them before they get tough and start producing new bulbs.

No, simply use a small shovel, like a spade, to dig a circle around the onion. Make sure you have already have a dug hole to transport the onion to and then lift the sprout out of the ground. Place the onion in the whole and make sure the dirt is compacted so that there is no air. Be careful not to let the onions roots get exposed to air.

You can still try but it will not work. This is because the root functions in water, and mineral absorption, as well as in the anchorage of plant bodies. Some roots also store sugars and become enlarged. So without the roots, it will not thrive.

For onions, you plan to harvest as scallions or spring green onions, an 8-inch (or larger) pot works fine. To raise bulb onions, you'll need a container wide enough so that each onion has about 3 inches of space around it. Many gardeners choose to grow onions in plastic tubs or half whiskey barrels.

Yes, you will. Matter of fact, you can get three onions from a sprouted one!

Yes it can. I have onions in my yard and they have been there through three winters.
