Frequently Asked Questions

Why are my Celery stalks tough and stringy?

Tough stalks usually result from inconsistent moisture or heat stress — keep soil consistently moist with deep watering 2–3 times weekly, since Celery needs a long growing season with steady moisture to develop tender stems.

When should I harvest Celery?

As a biennial, Celery is best harvested in fall or early winter after several months of growth — harvesting too early results in thin, underdeveloped stalks.
