Common questions
How much water does celery need?
Celery is water-sensitive — shallow roots and a steady thirst. Keep soil moisture in roughly the 50–70% range and don't let it dry out fully, or growth stalls and leafy crops turn bitter.
Can I grow celery in a raised bed or container?
Yes — celery does well in raised beds and is happy in a decent-sized container too, as long as drainage is good.
Does celery come back every year?
No — celery is an annual. It completes its life in one season, so you replant it each year.
