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.

Loop, Texas is in USDA Zone 8a. The average last spring frost is April 6 and the first fall frost is November 6, giving you a growing season of approximately 214 days.

At an elevation of 3,384 feet, Gaines County receives approximately 43.7 inches of rainfall annually with predominantly sandy loam soil. Summer highs average 100°F, so Celery may need afternoon shade and extra watering during peak heat. Sandy soil warms quickly in spring — great for early planting — but Celery will need more frequent watering and organic matter to retain nutrients.

Celery Heat Requirements (GDD)

What are Growing Degree Days (GDD)?

Growing Degree Days measure the total warmth your plants receive during the growing season. Think of it as a "heat bank" — every day above 50°F deposits warmth that helps your plants grow.

Each plant needs a certain amount of accumulated heat to mature. If your county provides more GDD than the plant needs, it's a great fit. If it's close, you may want to choose faster-maturing varieties or start seeds indoors to get a head start.

Celery needs ~2,500 GDD — county provides 5,350 GDD Excellent fit
