When to Harvest Celery

Asked June 17, 2018, 8:56 AM EDT

Hello UMCE: I live in Clarksville, Howard County, Maryland. I have a large vegetable garden and decided to try growing celery for the first time this year. I started the plants indoors in January, and transplanted very healthy seedlings to the garden in late April. Their present side and condition is indicated in the attached photo. My question is, when should these be ready for harvest? The seed packet says 100 days (I presume from setting out transplants, which would be late July), but some of the plants look ready now to me. Thanks for your insight!

Your plants look healthy. You can start harvesting the outer stalks when they are about 6 - 12 inches tall. Harvest what you need. You can leave them in all season. Celery likes a long cool growing season. Celery does not like it hot and dry. They like a lot of moisture. Any water stress during the year causes the stalks to become stringy and gives them a strong flavor. They can overwinter and will flower and go to seed next year. They are a biennial.
