can we grow onions at home?You can grow onions in a large pot at home, and this vegetable does not even demand too much of your attention and time. So, what better way to celebrate World Soil Day than to pledge to grow your own vegetables--well, at least the basics.
What happens if you put an onion in the ground? If you notice a green sprout emerging from the top of an onion, it means it's trying to regrow. By separating the sprouts inside an onion's layers and planting them in good soil you can grow multiple new onions within a single season.
can you grow onions from store bought onions?
Chop the onion about 1 in (2.5 cm) from the bottom. If you're growing the onions outside, start your cuttings in early spring. For onions grown indoors, any time of the year is fine. You can use most onion varieties, including grocery store-bought onions, for growing more onions.
What happens when you plant a whole onion? Planting Sprouted Onions. The outside will become dry and papery, and the whole onion will shrink as it puts stored energy into trying to make one last go at life.

how many onions can you grow from one onion?
Sets are small dry onion bulbs produced the previous year. They can be planted later in the year than transplants and still produce a marketable crop. Growers generally plant 75,000 to 120,000 onions per acre in single rows with 2 inches between plants in the row and 24 inches between rows.
How long does it take to grow onions? Twenty to 50 onions can grow in 1 to 1½ square feet of space. But onions are easily grown in odd spaces alongside both slower and faster growing vegetables. Green onions can be ready in 20 to 30 days after planting. Dry bulb onions can take 100 to 175 days to reach maturity.
How do I grow bigger onions?
Onion sets and onion plants require loose soil and should be planted early (end of February or March). Dig a shallow trench, working in compost or fertilizer for big onions. Likewise, raised beds can be implemented. Plant the onions about an inch deep and 4-5 inches apart.
How do you dry onions in the sun? Pull your onions up on a sunny day if you can, then let them sit in the sun for another day or so to dry (in hot climates this usually takes just a few hours). This drying kills the root system at the bottom of each bulb. The roots will be like little brittle wires when they're dry.
Do onions need a lot of water to grow?
In well-drained soil, onions need a thorough soaking of one inch of rain or water per week to grow best. Watering when onions are bulbing can keep some soils from hardening around the bulbs, allowing for bulb expansion.
Do onions come back every year?
If they do produce seed, to ensure seed purity you need isolation distances up to three miles. Finally, once you harvest the onion plant, it's gone. For all these reasons, consider some less common perennial onions. They're easy to grow and come back year after year, and you don't have to buy seeds every year.
How do onions reproduce?
Onions reproduce either with seeds or by bulbils (little bulbs) that form from lateral buds.  After the first growing season, mature bulbs can be left in the ground or dug up and replanted. Either way the plant will undergo a period of dormancy, then grow during the next growing season.
How do you grow onions in water?
Place the onions in a clear glass or jar with the root end down. Add just enough water to the bottom of the container to cover the roots at the bottom of the bulbs. Change the water at least every other day. Place the glass in a window that receives plenty of filtered sunlight throughout the day.
Do onions grow from bulbs?
You can grow red onions from seed, transplants or directly from the bulb. Red onions, unlike other varieties, grow especially well from a bulb, which is referred to as a set. Sets are small onion bulbs that will sprout, grow a stalk and grow several more onion bulbs.
How many onions should I plant?
In a well-tended plot, most of the onions you plant turn into good-sized bulbs. If you eat an onion a day, consider planting 400 or so seedlings or sets (or some combination of the two). That amount will take up 50 row feet of garden space. If you eat two onions a week, plant a little over 100 seedlings or sets.
Why is my onion flowering?
When an onion plant prematurely sends out a flower stalk, it's referred to as onion bolting. Onion bolting is a natural process that occurs when the plant is under stress. While we gardeners may enjoy the beauty and taste of our plants, we mustn't forget that the plants sole purpose is to reproduce.
How do you know when onions are done growing?
Squeeze the plant gently about 2 to 3 inches above the bulb to check for a soft spot on the top. This soft spot is a sign the bulb is done growing even if the tops look like they are still growing. Pull the onions that have the soft area on the top. Leave other onions growing so they reach maturity before harvesting.
How many potatoes do you get per plant?
If all conditions are ideal, you may harvest about five to 10 potatoes per plant for your gardening efforts. Yields are based on both the care your give your plants during the growing season and the variety of potatoes you choose to grow.
