Regrow celery by cutting the base of the celery off letting the celery base/ bottom soak in water (only on the bottom) for a couple days. When you see growth in the center transfer to garden and cut the top and bottom off a milk jug or soda bottle and put around celery to help the celery grow straight!
Regrow store bought celery and put a soda bottle around it so it will grow straight up.
