Sweetcorn Gucio

What Sweetcorn Gucio is

Sweetcorn Gucio (Zea mays) is an annual vegetable of the grass family (Poaceae). The sweet corn Guccio is an early variety that can reach up to 2 m. tall.

The cobs are 20 cm long. with yellow kernels.

Super sweet.

Home-grown sweet corn, boiled or roasted minutes after picking, is incomparably sweeter than shop-bought. Popcorn and ornamental varieties are a pleasure of their own.

When to sow Sweetcorn Gucio

Sweetcorn Gucio seeds are sown in March – May. Harvest in August and September. The months are a guide for a temperate climate — in warmer areas sow 1–2 weeks earlier, in cooler or upland areas, later.

How to sow and grow Sweetcorn Gucio

• Sowing method: direct
• Depth: 3–5 cm
• Spacing: 25–30 cm in the row, 60–70 cm between rows
• Germination: 6–10 days at 15–25 °C
• Position: sunny spot

Growing: sow the seeds directly into the soil at a spacing of 40x40 cm in mid-May; sow 2 to 3 seeds at a depth of 4 to 6 centimetres in the soil at each position. Thin the plants once the seeds have germinated, leaving two plants at each position. This variety loves sunny spots in nutrient-rich soils. Sweet corn can be grown in a variety of climatic conditions, but it requires high temperatures during the growing season. Sweet corn is a crop with high irrigation requirements and needs regular watering throughout the whole growing period. Harvesting should be done when the kernels are at the milk stage. During this period the silks of the cobs begin to turn brown and dry. 50% of the cobs are ready for harvest 20-22 days after tasselling. The cobs are in optimal condition for harvest for 3-4 days.

Sow in a block of at least 3–4 rows (rather than one long row) — this improves pollination and the cobs are full. Do not sow within 100 m of other corn if you want a sweet flavour.

Harvest and use

Sweet corn is ready when the silks turn brown and the kernel releases milky juice when pressed. Popcorn varieties stay on the plant until fully dry.

Frequently asked questions

When should Sweetcorn Gucio be sown?

The recommended sowing months are March – May. Sowing method: direct.

How many seeds are in the packet?

The packet contains 25–35 seeds, pack size 5 g.

What is the germination rate of the seeds?

The measured germination rate of this batch is 85%. The test was carried out under controlled laboratory conditions; in the field, emergence depends on soil, temperature and moisture.

Why are the cobs not full?

Most often from poor pollination — sow in a square block, not in a single row.
