Sowing Information

Sow in a propagator on a windowsill or in a greenhouse at minimum 18°C (65°F) using a good quality compost. Cover the seeds with 3mm (1/8") sieved compost (Germination 12-18 days). Transplant seedlings singly into 50mm (2") pots or into trays, grow on and finally plant out 20-30 (9-12") apart, in rows 38cm (15") apart when all frost risk has passed. Do not grow Celeriac in trenches.
Water regularly during periods of dry weather. Once the bulb starts to develop remove lower leaves to encourage further growth.
