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. Change out the water every couple of days while in the re-growing jars, or bowls or you can used a spray bottle to spray water directly onto the base of the celery where the leaves were growing out.
After the 5 to 7 days is completed, transferred the celery base to a planter and covered it completely save for the leaf tips with a mixture of dirt and potting soil.
Watered it generously and after planting in the soil, the overall growth really took off. Not only that the celery leaves regenerating themselves from the base, but you can see clear stalks making their way up and out. It's truly fascinating.
