You can regrow celery!
Yup, it's true. Normally you buy celery and chop off that ugly mess at the bottom and throw it away, right? Stop it right now!
Chop off that ugly mess and set it in a bowl of water. In a few days you'll see some leafy re-growth. Then it's time to plant it in the ground. Soon you will see new celery growing. What's that you say? You need proof? Oh, all right.
Those gardeners who know way more than I do (that would be all of them) say that it's a good idea to cut a 2 liter pop bottle in half, cut off the top and/or bottom, and use the plastic as a shield around the celery as it grows to keep snacking critters from spoiling your efforts.
So what do you think? Will you ever throw away the bottom of the celery again?
