reGrowing Our Organic Green Onions in the Balcony Garden

As our balcony garden grows we have focused on food we can grow in pots and grow quickly. With just a few internet searches we found people regrowing their green onions from the root bulb in little glasses of water on lit windowsills. We were so enchanted with the ease of regrowing them and the rapid growth of the green onions that we tried it at once.

Cut the green onion just above the root bulb.

We've anchored the onion bulb to a kabob stake for standing them upright with the roots in water and the tops in the air.

New roots and shoots form quickly, after two or three days in water.

The Green Onion bulb goes about an inch into the pot, with another inch or so down for roots.  The shoots poke up over the soil line.

We'll plant 4 of these 5 inch pots with 3 onions each for a dozen.

By sprouting these and planting them 1 and 2 at a time as we use them, they’ll mature 1 and 2 at a time and not all at once, letting us cut them back and eat them one at a time as they grow.

Here we have seven days of growth, showing the progress on the first set of three that we planted.

Here we’re planting our second set of three. Our plan is to have three onions in weekly rotation, for a month’s worth of a dozen. Since we won’t be eating them all at one time, having sets of three in weekly phases will insure we always have one ready every other day or so, and we’ll avoid having to harvest them all at once. Typically when we buy big bundles at a time from the grocery store we don’t eat them all before they go bad, and so we’ll also avoid waste.

Here is our second set of regrown green onions coming out of the rooting water and going into the potting soil.

These stayed in the water for a week, much longer than intended. The one on the left already in the soil – You can see how far along it has grown just in the water. And you can see the root bulbs of the ones about to be planted and how long the roots have grown. While leaving them in the rooting water will make them grow fast, the sooner you get them into the soil, the sooner they are receiving real nutrients promoting better taste and nutrition.
