Common questions
When should I plant celery?
Celery is one of the most demanding cool-season crops: it germinates slowly at 15-21 °C and needs 10-12 weeks of indoor growing time before transplanting out 2-4 weeks before the last spring frost. Temperatures below 10 °C for more than 10 consecutive days can trigger premature bolting, so protect young transplants with row cover in cold snaps. In zones 9-10 celery is typically grown as a winter/spring crop, started in late summer; in zones 3-6 the short cool window before summer heat sets in makes consistent irrigation and blanching (hilling or wrapping stems) essential for tender, mild stalks. Because the right window depends on your local frost dates, pick your US state above for a calendar with exact sow, transplant, and harvest dates.
Does the best time to plant celery vary by state?
Yes — planting dates swing by several weeks across the US because each state sits in a different USDA zone with its own frost window. Every state page here gives celery dates calibrated to that state's climate.
How are these celery planting dates calculated?
Each state's dates come from that state's dominant USDA hardiness zone and NOAA average frost dates, then adjusted for celery's cold tolerance and days to maturity.
