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.
Gardening in Idaho
Idaho has a semi-arid continental climate. Southern valleys are Zone 6-7 with hot dry summers; northern regions and mountains are colder. Excellent for root vegetables and cool crops.
