When to Plant Celery in Jasper County, TX

Celery is a marshland plant that requires consistent moisture and cool temperatures to produce crisp, flavorful stalks. It is a rewarding but demanding garden crop.

Jasper County, Texas is in USDA Zone 8b. The average last spring frost is March 3 and the first fall frost is November 22, giving you a growing season of approximately 264 days.
