Growing Onions Vertically On The Windowsill

You can do a lot of dishes with onions, but even if you aren’t a fan of this vegetable, there is always room for a thin piece of onion to add a bit of flavor to the meal you just prepared for your family or friends. And most of the times, you have some onions in the kitchen but it’s not as fresh as you would want. A nice solution to this is growing your own onions. Don’t panic, you won’t need a garden, because you are growing it vertically on the windowsill. This way, you’ll save space and be green! Here is what you’ll need:

    It is a fantastic idea. Thank you for sharing it. I thought that veggies needed to grow in the ground to absorb nutrients…is this right?… or am I missing something that I am not aware?
    Please let me know…

    Do you use the green sprouts or the actual onion bulb I’m confused

      You don’t eat the actual onion. You just cut and use the green sprouts. After cutting, they will regrow.

      Actually, the onions will not grow bigger and will eventually become smaller as it produce more greens. I would suggest that you reserve some greens to flower so that you may collect onion seeds after flowering. Otherwise, it is a waste of good onions in exchange of greens. 😦

    Om. Does this not require any manure ?

  18. I don’t get it, this isn’t technically regrowing the onion right? Why not just put green onions in a bottle with water and accomplish the same thing in a less messy manner?

    Hi, once the onion has grown and you pick for use, will another onion grow to replace the picked one or do you have to keep planting more onions Inside?

      I have tried planting onions that have developed inside the ref to harvest the greens. After some time, the onions will shrink & die out. If you are interested in harvesting onions, allow one to to bear flowers & once fertilized, onion seeds will form w/c will become the big onions. Better plant the roots of green onions if you just need the greens and just use the onions for cooking.

    I think the title of this article is misleading. I thought it was about growing ONIONS not the sprouts or whatever.
