Description
The 'Mergoscia' Corn is an ancient variety originating from the town of Mergoscia in the Swiss canton of Ticino. Each plant generally produces two complete, compact and well-formed cobs with golden yellow grains. This traditional variety is highly valued for making a coarse flour perfectly suited for making polenta. This corn, which loves sun and heat, however, has lower nutritional needs than modern selections. It is sown in April-May for a harvest from late August to October.
Corn plants like sunny exposures and need warmth: in the edge of the vegetable garden, they will allow to delimit the cultivation areas and provide shade for vegetables that need it (lettuce, cabbage...). Corn is a food rich in starch. It is the staple food for many populations. It is usually consumed cooked as grains or as a whole cob, but you can also grind it into coarse flour to consume it as polenta.
Harvest: corn is harvested approximately 3 months after sowing, depending on the heat and watering, when the silks start to turn brown. The grains should be well developed, but still tender. To check if they are ripe, take a few from a cob and crush them: they should be slightly milky.
Storage: after harvesting, remove the green husk that surrounds the cob and consume it quickly. To store them for a longer period, cook them and then preserve them in jars or frozen.
Gardener's tip: Traditionally, Native Americans cultivate corn in association with climbing beans and squash. These three plants benefit each other: nitrogen nutrition from the bean, support from the corn, and ground cover from the squash leaves. First, sow the corn. When it reaches 10cm (4in) in height, sow two bean seeds and two squash seeds around the corn.
Organic or "BIO" seeds come from plants grown in organic agriculture (without the use of phytosanitary products). They undergo no treatment after harvest. These seeds are suitable for organic market gardening.

Planting and care
Sowing maize:
Sow maize in full sun after soaking the seeds in warm water for 12 hours. In the garden, sow in May in well-warmed soil (at least 12°C (53.6°F)). You can install a tunnel over early sowings until the temperatures warm up enough. You can start sowings in buckets, indoors, as early as April, and plant them in May-June in the garden. Only sow one variety at a time, or two varieties with staggered flowering: maize hybridizes very easily and you wouldn't harvest the variety you sowed. If your garden is less than 200m (656ft) from a maize field, you will need to protect your crop during flowering.
To sow in rows, dig furrows 3cm (1in) deep, spaced 70cm (28in) apart. Sow thinly. After germination, thin to 25-30cm (10-12in) on the row. If you are only sowing a small number of plants, sow them in a square rather than one or two long rows, pollination will be better ensured.
To sow indoors, place 2-3 seeds per bucket in seed compost, mixed with a little compost. Then plant the best-developed plant.
Maize cultivation:
Maize likes rich soils: add manure or compost during its preparation, in the previous autumn, to enrich the area intended for sowing. The roots are shallow, so hoeing should be very superficial. To promote anchoring, mound up the maize when it reaches 20cm (8in), then 40cm (16in) in height. Water regularly if it doesn't rain (once a week), and cover the soil with mulch to retain moisture (grass clippings, straw...).
To facilitate pollination, when the female flowers (located two-thirds up the stem) turn beige, shake the plant. This way, the pollen from the male flower (located at the top of the stem) will fall onto the female flowers.
The corn borer caterpillar, a destructive maize pest, sometimes burrows through the stems, causing them to break. As a preventive measure, shred crop residues before using them (compost or mulch). Practice good crop rotation by not growing maize in the same plot for 3 or 4 years. In case of severe infestation, you can spray a solution of Bacillus thuringiensis.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).

The flowering period indicated on our website applies to countries and regions located in USDA zone 8 (France, the United Kingdom, Ireland, the Netherlands, etc.)
It will vary according to where you live:
- In zones 9 to 10 (Italy, Spain, Greece, etc.), flowering will occur about 2 to 4 weeks earlier.
- In zones 6 to 7 (Germany, Poland, Slovenia, and lower mountainous regions), flowering will be delayed by 2 to 3 weeks.
- In zone 5 (Central Europe, Scandinavia), blooming will be delayed by 3 to 5 weeks.
In temperate climates, pruning of spring-flowering shrubs (forsythia, spireas, etc.) should be done just after flowering.
Pruning of summer-flowering shrubs (Indian Lilac, Perovskia, etc.) can be done in winter or spring.
In cold regions as well as with frost-sensitive plants, avoid pruning too early when severe frosts may still occur.
The planting period indicated on our website applies to countries and regions located in USDA zone 8 (France, United Kingdom, Ireland, Netherlands).
It will vary according to where you live:
- In Mediterranean zones (Marseille, Madrid, Milan, etc.), autumn and winter are the best planting periods.
- In continental zones (Strasbourg, Munich, Vienna, etc.), delay planting by 2 to 3 weeks in spring and bring it forward by 2 to 4 weeks in autumn.
- In mountainous regions (the Alps, Pyrenees, Carpathians, etc.), it is best to plant in late spring (May-June) or late summer (August-September).
The harvesting period indicated on our website applies to countries and regions in USDA zone 8 (France, England, Ireland, the Netherlands).
In colder areas (Scandinavia, Poland, Austria...) fruit and vegetable harvests are likely to be delayed by 3-4 weeks.
In warmer areas (Italy, Spain, Greece, etc.), harvesting will probably take place earlier, depending on weather conditions.
The sowing periods indicated on our website apply to countries and regions within USDA Zone 8 (France, UK, Ireland, Netherlands).
In colder areas (Scandinavia, Poland, Austria...), delay any outdoor sowing by 3-4 weeks, or sow under glass.
In warmer climes (Italy, Spain, Greece, etc.), bring outdoor sowing forward by a few weeks.
