Germination Temperature Range
60°F soil
Spacing Between Plants

Growing conditions
Celery is easy to grow in full sun and with slightly acidic soil. Water more often than most vegetables at 1-2" of water per week.
Companion Plants
In cooler climates, tomatoes make an excellent companion crop for celery; in warmer locations, plant celery with spinach, greens, lettuce, or brassica plants such as broccoli.
Rotation

Anticipated yields
Plan your garden yield at five plants per person.
