Native to Europe and Asia, this salad vegetable is grown for its thick, crunchy stalks.
Needs long period of warmth but not high heat. Plant seeds in flats in early spring; where winters are mild, start in summer for winter crop. (Celery plants started from seed are slow to reach planting size; to save time, you can purchase small nursery plants.) Plant seedlings in rich soil, spacing 6 in. apart in rows 2 ft. apart. Every 2 to 3 weeks, apply liquid fertilizer with irrigation water. To keep plants upright, work some soil up around them as they grow. For whitened stalks, set bottomless milk carton, tar paper cylinder, or similar device over plants to exclude light from stalks (leaves must have sunlight). Or grow self-blanching varieties.
Use row covers to keep pests off plants.
Harvest 105 to 130 days after transplanting.
