Celery is commonly grown in trenches which are deeply dug and prepared with a layer of rotted manure or compost at the bottom. Celery plants require a regular feeding and watering during the growing season.
Self-blanching varieties require much less work, but are not as flavourful as trench-grown plants which must be carefully wrapped with newspaper and tied, but not tightly. Soil is then mounded up until just the leaf tops show.
Harvesting may start in mid autumn in milder regions and may end in late autumn.
It has one of the highest potassium contents of the vegetables and can be eaten raw or cooked. The seeds are also used in cooking.
