Description

'Conquerer F1' sweetcorn is a late-maturing hybrid variety that is recommended for growing in regions with shorter, cooler summers. It produces an average of 3 long cobs per plant. Good quality flavour. Sow in spring and harvest from August to October.

Sweetcorn (Zea mays), also known as pole corn or sugar corn, is a form of maize that has a particularly high sugar content due to a naturally occurring genetic mutation. It belongs to the Gramineae family alongside wheat, barley and rice. It is highly nutritious, containing more protein and five times more fibre than rice. It is also an excellent source of B vitamins, vitamin C, minerals and trace elements. It has a low glycemic index.

Sweetcorn likes deep, light, cool soil that is rich in organic matter. It is a heat-loving plant that needs plenty of sunshine to grow. It can be used to create attractive borders around your vegetable garden and individual plots whilst providing valuable shade for vegetables such as lettuces or cabbages.

Harvesting: Sweet corn is harvested 80 to 120 days after sowing depending on the amount of sunshine and water it has received. The ears are ready to be picked when the silks start to turn brown and the kernels are well developed. Check for ripeness by piercing a kernel with your fingernail - it should be tender and milky. When harvested too late, the sugars turn into starch and the skin becomes tough.

Storing: after harvesting, remove the green husk that is wrapped around the ear. Use quickly, the fresher the better! Sweetcorn can also be cooked and frozen or preserved in jars for later use.

Good to know: Traditionally, maize crops were grown alongside squash and bean plants in Central and South America in a system known as Milpa agriculture. Beans would enrich the soil with nitrogen, squash plants would act as ground cover and maize plants would provide support for the beans to scramble up. Start out by sowing your maize plants. When they are about 10 cm tall, sow 2 bean seeds and 2 squash seeds around each young plant.

NB: This variety is marked F1 for "F1 hybrid" meaning that its qualities are derived from carefully selected parent plants. This results in a variety that is both full of flavour and resistant to diseases. Sometimes criticised or wrongly assimilated to GMOs, F1 hybrid seeds have the advantage of producing reliable, uniform, disease resistant plants. Unfortunately, these qualities will not be passed on to following generations.

Planting and care

Corn thrives in the sun, in loose and rich soil. Add compost in the previous autumn.

In spring, between April and June, corn can be sown in rows or in holes. The soil should be sufficiently warmed (12°C). In colder regions, sowing in holes of 3 to 4 seeds can be done in buckets, indoors, with seedling soil and a bit of compost. The most beautiful plant will then be transplanted into the ground around May-June.

Row sowing: stretch a cord and dig trenches a few centimeters deep, spacing the rows 70 cm apart. Sow one seed every 10 cm, cover with fine soil and gently press down with the back of a rake. After germination (about ten days), thin out to keep one plant every 20 cm.

Hole sowing: sow in holes of 3 or 4 seeds (25 cm apart in the row and 80 cm between rows). Germination occurs about ten days after sowing. Thin out when the seedlings have 4 leaves to keep only the best-developed plant.

Sow in staggered intervals (every 15 days, for example) to spread out the harvest.

When the corn reaches about 30 cm in height, hill it up to a height of 10 cm to promote anchoring in the soil.

Hoeing and mulching will be necessary. Make sure to hoe on the surface as corn roots are shallow. Corn needs to be watered regularly, about once a week if it doesn't rain. The rotation between 2 corn crops is about 4 years.
