Onions are easy to grow both outdoors and inside. If you don’t have the space for a garden outside, you can grow them indoors. You can even have an endless supply of them if you do it just right since onions are a cut and come again vegetable. (they will regrow from the original stock with roots.)
Here are a few of the ways to grow onions indoors.
Slice Off Onion Bottom
Note: You might only need a few hours for callousing. If the cut portions are dry to the touch and slightly shriveled, it very well might be calloused enough.
Note: You can skip the starter pot if you can’t be bothered and plant it directly in the ground.
– Buy one clump of spring onions at the store.
-Use your green onion as you normally would, but reserve the roots and keep at least one to two inches of the white bulb intact.
-Place the rooted bulbs in a glass with water by a window.
-In just a couple of days, the green stalks will start growing back.
-In about a week, you’ll be able to use them again.
Just be sure to change the water ever couple of days and rinse the bulbs. And it doesn’t stop with green onions.
Grow onions vertically on a window sill. You will need a 5 liter bottle that you have made holes in. Fill it with potting soil and onion sprouts and watch your harvest grow indoors!
Do you ever reach into the onion bin and find one that has sprouted? Don’t just use part of it and discard. Put that sprouted part to work. Slice into the onion to expose the sprout and carefully cut the onion in two (take care not to disturb the sprout). Carefully cut around the sprout and plant. You can use the part not planted but will end up with another onion too!
