Celery

Trenching is the traditional method of growing celery and they usually have large white, pink or red stems that are blanched before using them. Dig the trenches, 38cm (15in) deep by 30cm (12) wide, in autumn, adding plenty of organic compost to enrich the soil. Sow seeds indoors from March to May and plant out into the trenches from May to June. Make sure the celery is kept well watered, especially in dry weather. When the plants are about 30cm (12in) tall, tie the stems loosely and gradually earth them up as they grow to blanch them.
