Maize (Sweetcorn)

Maize (Zea mays) is a tall grass grown for its sweet cobs, needing warmth and plenty of light to crop well. Sugar-rich varieties grown for human consumption are referred to as sweetcorn. Field corn varieties are generally used for animal feed.

Maize can be boiled or grilled on the cob or cut off and used in salads, soups and fritters. It’s best eaten as fresh as possible, as its sweetness fades quickly after picking.

Maize is cold-intolerant and prefers a sunny, sheltered spot and rich soil, as its roots are shallow. It should be planted in blocks rather than rows for good pollination.

Sow it in May under cover, then plant it out after frosts.

You can harvest maize from August to September, when the tassels have turned brown and kernels are milky when pressed.
