About Celery

Celery is a long-season crop that demands rich, constantly moist soil and a long cool growing period — hard to grow perfectly, but worth it for the flavor.

Start indoors 10-12 weeks before last frost. Blanch stalks by hilling soil or wrapping 2-3 weeks before harvest. Keep soil consistently wet — celery hates drying out.
