The plants are raised from seed, sown either in a hot bed or in the open garden according to the season of the year, and after one or two thinnings out and transplantings they are, on attaining a height of 15–20 cm, planted out in deep trenches for convenience of blanching, which is affected by earthing up to exclude light from the stems.1
Celery requires a sunny location along with regular watering and feedings4. The plants need at least 1 inch of water per week from rainfall or watering4. Soak the soil when watering, as lack of water produces stringy stalks4. The plants need aged compost tilled into the soil before planting and side-dressing with compost at mid-season4. Celery is a heavy feeder5.
Celery can also be grown in containers – choose 5-gallon (20 litre) containers that are at least 8 inches (20 cm) deep4. Container-grown celery will require more water.
Requires about 16 weeks to harvest. You should aim to grow about 5 plants per household family member5.
