How to grow celery

Sow seed 0.1cm deep in pots. Harden off and transplant 15-30cm apart. Plant 'trench' varieties at the base of a 10cm deep trench, backfilling left-over soil to blanch.

Water in dry weather.

Harvesting and using celery

Dig up as required, finish harvesting self-blanching varieties before frosts and trenched plants from October. Harvest before leaves yellow.

Tips on growing celery

For best flavour, blanch trench varieties when 30cm tall (tie newspaper columns are stems, leaving leaf tips showing and pull soil around).
