A good start: warmth and light
Warm sowing can be done indoors or in a heated greenhouse. After germination, every seedling needs enough light. A dark attic needs grow lights. An unheated greenhouse can become very cold at night: measure the temperature and check the advice for your crop.

- Germination and temperature
- Germinate in warm, bright conditions according to species guidance. Protect young plants from prolonged cold; keep celeriac above about 10 °C.
- After emergence
- Give seedlings light immediately after emergence. A dark loft needs suitable grow lights; warmth alone is insufficient. Ventilate and keep the compost moist without saturating it.
- Pricking out and potting on
- Sow fine seed shallowly according to the packet; prick out manageable seedlings into individual modules.
- Hardening off and planting out
- Gradually acclimatise indoor-raised plants to sun, wind and outdoor temperatures; shelter them again on cold nights. Plant in late spring or early summer during milder weather. Keep the heart of celeriac above ground.
Celeriac has a long season. Celery and leaf celery have different harvest aims; use their own cultivar instructions.
