To grow an onion in water, place the onion's bottom root end in a container of water, making sure the water covers the roots. Change the water every few days and place the container in a sunny spot. The onion will start to grow roots and eventually sprout green shoots.
Yes, as long as you have soil, water, and an onion sprout, you can indeed grow an onion in your belly button.
Green onions tend to grow faster in water compared to soil because they can easily absorb the nutrients and water they need for rapid growth. Additionally, growing green onions in water allows you to observe their growth progress more clearly as the roots develop.
You do not need to put an onion root in water, also cutting its roots would not have done any favours to the onion. If you keep the onion in dry and aired environment it will start to sprout naturally and can then be planted.
Unlike many other vegetables, onions can be used to regrow new onions by planting either a whole onion bulb or part of the onion that contains the root mass on the bottom. Once planted and hydrated, the roots on the bottom of the onion will begin to grow, and green onions will form out of the top of the vegetable. Onions can be used to grow new onions either using water - which is called hydroponic growing - or traditionally, using soil.
Water is much healthier for green onions because green onions require water than soil to make the grow.
