Celery can be commercially harvested by removing the top portion of the celery plant to leave the bottom portion of the celery plant attached to the stem in the ground. After removing the top portion of the celery, the celery is cut above the stem to separate the plurality of individual petioles. The separated individual petioles are then washed, and packaged into a sleeve. The top portion of the celery plant, the separation of the plurality of individual petioles, as well as the washing of the individual petioles are performed in the field in which the celery plant was grown.
