The glass or jar should be tall enough so that it can keep the green onions upright. For example, a pint glass or a large canning jar works well.
Even if the roots themselves have been trimmed off your green onions, but the root end remains, the plant will grow new roots in water.
It may be easiest to use the produce bag that you brought the green onions home in.
The plastic bag does not need to be totally sealed so that it is airtight. You simply want to keep some of the humidity from the water around the onions. If the plastic bag was not there, the refrigerator would remove all of it.
When you want to use your onions, just take the container out, remove the bag, remove an onion, place the plastic bag back on, and put it back in the fridge.
When you change out the water, you can also rinse off the green onion root sections. This will help to remove any bacteria or mold that might be starting to grow on them.
Green onions will last a long time stored in either water or soil on your windowsill. Deciding between the two is based mostly on personal preference.
Green onions should be placed 2 inches (5. 1 cm) apart when planted in soil. [7] X Research source
Having your green onions continue growing is a perk of storing them in the sunlight, as opposed to in the fridge. Green onions stored in the fridge will not continue growing. Typically, a sunny windowsill in your kitchen is a great place to store green onions or scallions. This makes it easy for you to remember to use them when you are cooking a meal.
Green onions should be kept in moist, but not overly wet, soil.
If there are sections of the green part of the onion that go brown and shrivel, simply trim those off or leave them. Once you trim the greens the tips tend to brown and the onion will grow a whole new green sprout.
Removing the packaging will allow the green onions to be removed from the bundle more easily and will minimize the chance of the onions being damaged by the rubber bands.
To make sure that the paper towel is not too wet, you can wrap the onions in a dry paper towel and then sprinkle a bit of water over the top of the towel.
The plastic bag can be placed loosely around the bundle of onions. It does not need to be completely airtight.
When you use some of your green onions, be sure to re-moisten the paper towel if it has dried out. Then place the bundle back in its plastic bag and put it all back in the fridge.
