Sweetcorn Plants FAQs

Take a look at some of the frequently asked questions we receive from those looking to buy Sweetcorn Plants in the UK. You can contact our Customer Service Team or browse our general FAQs for further advice.

When to plant Sweetcorn Plants

Sweetcorn plants should be sown indoors from April to May and transplanted outdoors in late May or early June when the risk of frost has passed. Direct sowing can also be done in late spring when the soil has warmed to at least 10°C. For best results, plant in blocks rather than rows to encourage better pollination.

How to Plant Sweetcorn Plants

Choose a sunny, sheltered location with well-drained, fertile soil. Enrich the soil with compost or well-rotted manure before planting. Space plants 30-40cm apart in a grid pattern to facilitate wind pollination. Water well after planting and keep the soil consistently moist throughout the growing season.

How long do Sweetcorn Plants take to grow

Sweetcorn plants typically take 14-16 weeks to reach maturity. The cobs are ready to harvest when the kernels release a milky liquid when pressed. Harvest promptly to enjoy the best flavour and texture.

Why should I plant Sweetcorn Plants?

Homegrown sweetcorn offers unbeatable sweetness and flavour, far superior to shop-bought varieties. Freshly harvested cobs are packed with natural sugars that start converting to starch immediately after picking, making homegrown sweetcorn the best choice for maximum sweetness. Growing sweetcorn is also rewarding, as it requires minimal maintenance once established.

Where can I plant Sweetcorn Plants?

Sweetcorn thrives in open garden beds or raised beds with full sun and protection from strong winds. It is best grown in clusters rather than rows to aid natural pollination. In cooler climates, using cloches or fleece early in the season can help improve germination and growth.
