We have selected these four varieties of sweetcorn for their vigorous, strong stems, sweet flavours and of course, their tolerance of our British summer weather. Varieties in this mixture include - Lark F1 Hybrid, Ovation F1, Conqueror F1 Hybrid and Northern Extra Sweet F1 Hybrid. Height: 210cm (83"). Spread 45cm (18").
Sow sweetcorn seeds from April to May in 7cm (3") pots of free draining seed compost at a depth of 2cm (¾"). Place in a propagator or seal the container inside a polythene bag at temperature of 18-24C (64-75F) until after germination which takes 7-10 days. After germination, grow sweetcorn plants on in cooler conditions for 10 - 14 days. When all risk of frost is passed, transplant into fertile, well drained soil in full sun, with shelter from winds. The tassels at the top of the plant and laden with pollen and are wind pollinated and should therefore be planted in blocks rather than rows to ensure good pollination. Plant 45cm (18") between each plant.
Alternatively direct sow sweetcorn seeds outdoors in May once the soil has warmed, at a depth of 2cm (3/4") and a distance of 35cm (14") apart. Sow 2 seeds per station and thin out the weakest seedling per station after germination.
Water sweetcorn plants regularly until established, particularly during dry periods. Provide a thick mulch of organic matter around the base of the plants to help conserve moisture and reduce weed growth. Sweetcorn plants are shallow rooted so take care when hoeing to prevent root damage. Harvest sweetcorn cobs when the silky tassles at the end of the cob have turned brown. Peel back the sheath of the cob slightly and press the corn kernels with a fingernail until liquid squeezes out. If liquid is milky coloured then the cob is ripe, if clear then it is under-ripe.
