Has anybody seen the posts on Pinterest about regrowing green onions? They say to put the white parts, with roots into water after you do your chopping. Well we decided to try it! :) They almost instantly started to change, it was pretty cool. They inner most parts seemed to be coming outward, giving the appearance they were growing. I changed the water at least daily, because it was stinky! After a week I am sad to report that all onions because limp, stinky and lacking at growth! Our excitement was short lived LOL But it was a fun project to try! :)
You can see the "growth" here.
