Well-grown celery requires a constant supply of moisture and food, performing best in well limed soils. For early crops sow under glass but for later sowings outdoor seedbeds are suitable.
Sow 5 mm deep, transplanting to 30 cm apart. Best sown August to December in cold and temperate areas. Water freely at all times and ensure good nutrient levels. Expect germination in 2 to 3 weeks at 20 deg.C. soil temp.
