What is the growing cycle of celery?

Celery typically has a growing cycle of about 90 to 120 days from seed to harvest. It is usually started indoors 10-12 weeks before the last frost date and then transplanted outdoors. Celery thrives in cool weather and requires consistent moisture and rich soil to develop its characteristic crunchy stalks. Harvesting occurs when the stalks reach a desirable size, usually around 8-12 inches tall.
