Sweetcorn is a delicious summer crop
You’ll need a large area and a sunny aspect, but this plant is a true delight when homegrown
TL;DR
- Sweetcorn thrives in long, hot summers with fertile, moisture-retentive soil and plenty of sun.
- Start seeds indoors with warmth for germination and plant seedlings out after the last frost.
- Plant in blocks of at least four by four plants with 40cm spacing to ensure successful wind pollination.
- Sweetcorn can grow up to two meters tall and may require staking for support.
- Cobs are ready when the liquid from a tested kernel is creamy.
- Overripe cobs can be dried for popcorn.
