When to Harvest Sweetcorn

Sweetcorn is ready to harvest once the cobs are fully developed and kernels are soft and juicy. Harvesting at the right time helps ensure the best flavour and texture.

In the UK, sweetcorn is usually harvested in late summer, depending on planting time and weather.

Checking the cobs helps you harvest at the right stage.

Signs sweetcorn is ready to harvest

Sweetcorn is usually ready when:

  • the silk at the top of the cob turns brown

  • cobs feel full when gently squeezed

  • kernels release a milky liquid when pressed

Harvesting at this stage usually produces the sweetest flavour.

Harvesting sweetcorn carefully

Twist or cut the cob from the plant.

Harvest soon after cobs become ready.

Sweetcorn often tastes best when used soon after picking.

Harvesting container sweetcorn

Sweetcorn growing in containers can be harvested in the same way as garden-grown plants.
