The taste of home grown celery is unmatched with store bought. I love it. I think if you just harvest the outer stalks, the plant will keep growing and produce more from the med section. Celery has a long growing season and would be hard to start more plants this late in the year. Unless you live the the south. My seeds inside did not grow this year. ( disappointed ) Theirs always next year for me I guess. Hahaha. Great article, Thanks
