April for an unheated greenhouse; late April for outdoor cultivarsStart indoors in warmth and reserve enough bright space for raising plants.
- 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.

Guideline periods for the Netherlands and Flanders. Check the variety, available light, soil and measured temperatures. Greenhouse heating does not guarantee enough winter light.
