When to Plant Celery in Texas

Growing Celery in Texas: Complete Guide

Celery (Apium graveolens) is a warm-season crop that needs a head start indoors before Texas's last frost. Most Texas gardeners begin seeds indoors around Tuesday, December 2, 2025 and move transplants outside around Tuesday, February 24, 2026, after the risk of frost has passed.

Because Texas stretches across 9 USDA hardiness zones (6b, 7a, 7b, 8a, 8b, 9a, 9b, 10a, 10b), planting windows can shift by as much as six to eight weeks from one end of the state to the other. Gardeners in the warmer southern zones can start earlier, while those in cooler northern zones should wait until the zone table above shows their last frost has passed.

With 130 days to maturity, Celery needs the indoor head start that Texas's growing season requires. Starting indoors ensures you have strong transplants ready the moment outdoor conditions are right.

Celery requires full sun and regular moisture. Most of Texas receives adequate sunlight during the growing season, though gardeners in humid eastern regions should watch for fungal issues and ensure good air circulation.
