See these green and perky scallions? They weren’t so perky a week ago. In fact, they were chopped down to their roots. But a scant week of water and a windowsill grew them back — did you ever learn how easy this is?

I saw this little tip at a blog:

…there were no words, and the picture didn’t need any. Pop your cut scallions in a glass of water and, clearly, they regrow. I had to try it for myself.

I chopped off some scallions and stuck them root-down in a Mason jar above my sink. I topped off the water once or twice when I saw that it had mostly evaporated, but other than that I did nothing.

To my surprise, these grew fast. Within a day or two there was fresh growth, and within a week they had 3 to 4 inches of fresh green onion on top. (The before photo is actually after I cut them for the second time, and I originally chopped them off even shorter.)

It might not work a second time; I am not sure how long you can keep regrowing these things. But it’s handy and surprisingly practical, as I usually only use a bit of scallions at a time — a handful for miso soup or scrambled eggs here and there. It also gives me a bit of something green to look at.

Have you ever tried this? How long can you keep a set going?
