I’ve talked about growing plants from the grocery store and how to re-grow green onions by planting the root, so naturally I was fascinated with this post on how to grow celery from the root. All you do is cut the bottom of the celery off, like so:
Then you stand it in a saucer of water for about a week, until the little yellow leaves begin to turn green and grow. At that point, you plant it in dirt and eventually a new celery stalk begins to emerge.
As the site says, if this works, you may never have to buy celery again. [The Kitchn]
