Regrowing Celery - Don't toss that celery base! Did you know you can use it to re-grow a new bunch of celery? Just stand the base in a small dish of water for a week or so until new leaves appear in the center. The leaves will be yellow at first, and once they really emerge and turn green, you can plant the celery in the ground or in a pot.
