How To Grow

There’s something special about growing your own sweetcorn. Picked fresh and cooked within minutes, homegrown cobs are bursting with sweetness and flavour that shop-bought simply can’t match. Sow early and give plants a warm, sunny spot and you’ll be rewarded with golden kernels perfect for summer feasts.


Indoor Sowing
Sow one seed per pot in moist seed compost from April, keeping them on a sunny windowsill or in a heated propagator. Sweetcorn loves warmth, so this head start helps plants grow strong. Once seedlings reach around 15cm tall and frosts have passed, they’re ready to move outdoors.


Planting Out
Harden off seedlings gradually over 7–14 days before transplanting. Plant 2.5cm deep, spacing 45cm between plants and 45cm between rows. Grow in blocks rather than rows for better pollination and fuller cobs.


Outdoor Sowing
Direct sow once soil has warmed and frost risk has passed. Choose a sunny, sheltered spot and sow in blocks for reliable pollination.


Harvesting
Check readiness with the fingernail test: peel back the husk and press a kernel. If the liquid is milky, the cob is ready to harvest.


Companion Planting
Grow sweetcorn with climbing beans and squash—the traditional “three sisters” planting—where beans add nitrogen and squash shades soil to keep weeds down.
