Celery Leaf tips: Leaf celery can be a bit tricky to get going, it is not recommended to sow direct. Start indoors in pots or modules from February, or under cover from March; ideally keeping the temperature above 10C. The seeds should be surface sown as they need light to germinate. Water them from underneath, never from above. The pots or trays can be covered with cling-film to retain moisture. Plants can be transplanted when they have a few true leaves and are still small.
