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.

Popcorn maizeStart under cover in warmthApril–May
April–MayStart indoors in warmth and reserve enough bright space for raising plants.
- Germination and temperature
- Warmth helps germination; use cultivar instructions for temperature.
- 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. After hardening off and the last frost, usually late May–June. Plant root balls in a block for pollination.
Do not leave young sweetcorn in small pots too long. Popcorn needs enough season for cobs to ripen and dry.
