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 warmth, around 20 °C; young plants remain sensitive to cold.
- 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 in individual pots or deep modules. Do not prick out bare-rooted; move the whole root ball before the roots become restricted.
- Hardening off and planting out
- Gradually acclimatise indoor-raised plants to sun, wind and outdoor temperatures; shelter them again on cold nights. Move an intact root ball to its final position only when soil and nights are warm enough. Outdoors after the last frost, usually late May–June.
A February start requires an actually heated greenhouse for growing on. Choose a greenhouse or outdoor cultivar suited to your final position.
