Enjoy trying sweetcorn Alliance on your own plot; every cobs on each plant is packed full of juicy kernels from the base to the tip and your plants are particularly tough to withstand the varying weathers typical in a UK summer.

We recommend that you find a space to form a grid of sweetcorn. This means the female flowers are more likely to catch the pollen off the male flowers at the top of the plants and give you cobs quicker.

When your plant start to flower at the top of the stem (they look like a fountain of seeds) tap the stems to encourage the pollen to fall and fertilise the female flowers below which form the edible cobs.

How to sow:

Sow indoors or outdoors to suit your vegetable plot and whether you have a greenhouse to grow seedlings on. The good news is that the seeds of sweetcorn are nice and big so easy to handle.

If you have a greenhouse sow seeds indoors from March to May in individual pots 2cm (3/4in) deep filled with moist compost specially formulated to grow on seedlings. Put your pots somewhere with an ambient temperature of 18°C (64°F) until transplanting. Plant out in June.

Sow outdoors in May to August 2cm (3/4in) deep on a moist seed bed 25cm (10in) apart in a grid formation. Water regularly.

Please note that these great value seeds have a recommended sow/best before date of 2022 making them perfect for sowing this year. We put this date on simply to ensure the freshest seed for the best possible germination results. If you are purchasing now for next year’s sowing we expect the seed to still be viable as they are packed and stored by us in optimum conditions but you may notice slightly lower germination rates depending on how and where you store them
