I hope you weren't expecting an overly positive "I saw this on Pinterest and it's mind blowing" post. It's not. I just want to clear something up. Yes, you can root green onions, obviously...everyone's doing it! My issue is that I keep seeing people write "OMG, I'm never buying them again." Yes, you will, b/c onions are funky and funk up a water bath fast. Meaning, you will get one good batch of re-grown herbs, maybe two if you are lucky. Even if you change out the water twice a day, the jar will -without a doubt- end up reeking and the bulbs will -without a doubt- become a slimy mess.
Just thought I needed a PSA today.
