Why Has My Celery Bolted and Is It Still Edible?
Certified GKH Gardening Expert
Unlike many other crops, which bolt due to heat, celery will bolt prematurely if plants are exposed to too many days with temperatures below 55°F., especially if planted too early. Growing celery works best at daytime temperatures of 60° to 85°F.
Once a plant has fully bolted, the plant is normally inedible. It tends to be tough and woody, or even bitter tasting.
