Onions: a brief overview

Onions are a member of the Allium family, which also includes garlic, shallots, leeks, and chives. The onion plant has a long, thin, white root and a white or yellow-brown bulb.

The bulb is surrounded by thin, papery layers of skin. Onions are used as a food ingredient in many dishes, and they are also used as a source of flavoring or as a Garnish.

Onions are a good source of dietary fiber, and they also contain vitamins A, C, and E. Onions are low in calories and fat, and they are a good source of antioxidants.

Onions are grown in many parts of the world, including the United States, Canada, Mexico, and Europe. In the United States, onions are grown in every state except Alaska.

The Different Types of Onions

Onions come in many different shapes, sizes, and colors. They can be white, yellow, red, or even purple. Some onions are more pungent than others. Depending on the type of onion, they can be used for different purposes.

The most common type of onion is white onion. It has a milder flavor and is often used in salads or as a garnish. Yellow onions are a bit sweeter and are often used in soups or stews. Red onions have a sharper flavor and are often used in salsa or as a topping on burgers.

There are also many different types of specialty onions. The shallot is a small, delicate onion that has a milder flavor. The Vidalia onion is a sweet onion that is often used in salads or as a side dish.

 Onions are often used in seasoning meat, chicken, and seafood. Even though an onion may seem like a simple ingredient, it is actually very complex and can be used in many different ways.

How Long Do Onions Take To Grow

Underneath their dry, papery skin, onions are hiding a secret: they take a long time to grow. Depending on the type of onion, it can take anywhere from three months to five months to fully mature.

For gardeners who want to get a jump on the growing season, onion sets can be planted as early as late winter. These are small onions that were grown the previous year and then dried for storage. Once planted, they will quickly start putting down roots and sending up green shoots.

If you start from seed, you’ll need to be patient since it takes about six weeks for the seedlings to appear. But once they do, they’ll grow quickly and will be ready for harvest in two to three months.

Harvesting and Storing Onions

Onions are one of the staples in any kitchen, and they’re surprisingly easy to grow at home. Here’s a step-by-step guide to harvesting and storing your own onions.

Harvesting Onions

Onions are ready to harvest when the tops have fallen over, and the bulbs are big and firm. Cut the tops off about an inch above the bulb, then gently loosen the soil around the onion with a fork. Gently lift the onion out of the ground, being careful not to damage the skin.

Once you’ve harvested your onions, brush off any dirt and allow them to air dry in a cool, dark place for a few hours. Once they’re dry, you can either store them whole or cut them into pieces.

Storing Onions

If you’re storing onions whole, the best way to do it is to keep them in a mesh bag in a cool, dry place. A root cellar or basement is ideal, but a cool closet will also work. Hang the bag of onions in a cool, dry place and allow the air to circulate around them.

If you’re storing onions in pieces, you can either keep them in a covered container in the fridge or freeze them. Cut onions will only last a few days in the fridge, so if you’re not planning on using them right away, freezing is the best option.

To freeze onions, simply chop them into the desired size and spread them out on a baking sheet. Place the baking sheet in the freezer and allow the onions to freeze solid. Once they’re frozen, you can transfer them to a freezer bag or container. Frozen onions will keep for up to six months.


Onions do grow underground. They are root vegetables and need to be in contact with the ground to grow properly. They need a lot of water and prefer a cool climate. If you want to grow onions, make sure you have the right conditions for them and plenty of space.
