Celery has been grown around the Mediterranean for centuries, valued for the clean, savory flavor it brings to soups, stocks, salads, and countless everyday meals. In the garden, its crisp green stalks rise slowly from a small crown, building strength over a long, steady season.
Celery is a cool-season crop that rewards patience. It grows best in fertile soil with even moisture and mild temperatures, turning tiny seed into a full, useful harvest when conditions remain steady from start to finish.
Growing Guide
Timing
Start celery indoors about 10–12 weeks before the expected last spring frost. The seeds are tiny and slow to germinate, often taking two to three weeks, so celery should be started earlier than most vegetable transplants.
Set hardened plants outdoors near the last frost once the weather is reasonably settled. Celery tolerates cool conditions, but prolonged exposure to cold after transplanting can cause premature flowering instead of good stalk formation.
Sowing & Starting
Press the seeds onto the surface of moist seed-starting mix and cover them only lightly. Keep the surface evenly moist and provide gentle warmth until seedlings emerge.
Once plants are established, give them bright light and steady moisture. Move crowded seedlings into individual containers if needed, then harden them gradually before planting outdoors. Space plants about 8–12 inches apart, with enough room between rows for airflow and harvest. Celery transplants successfully, but young plants need careful handling and should never be allowed to dry out.
