When to plant Celery
Celery is a slow cool-season crop, usually transplanted. Start seed indoors in late winter and set transplants out in mid to late spring once hard frosts have passed; avoid prolonged cold, which triggers bolting (USU).
The calendar shows this cited seasonal window as an approximate band. It does not convert the season into frost-adjusted dates.
