Description

Sweetcorn ‘Double Red’ is an eye-catching, early-maturing variety with striking red and purple kernels. Packed with sweet flavour and boosted by anthocyanin-rich pigments, it offers both taste and nutritional value. The sturdy plants grow to 1.8–2 metres tall, producing 1–2 well-filled cobs per stalk. The 15–20 cm cobs can be enjoyed fresh or dried for popcorn. A vibrant alternative to standard yellow corn, ‘Double Red’ brings colour, flavour, and interest to any vegetable plot. Ultimate height: 180cm (6ft). Ultimate spread: 50cm (1.6ft).

Sowing

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.

More Info
Feed and water sweetcorn regularly, particularly once the flowers have developed. Hoe between plants regularly to prevent weeds from establishing. When the silky tassels at the end of each kernel turn brown, peel back the cobs and insert a thumbnail into a kernel. The cobs can be harvested when the juice is a milky colour.
