Sweetcorn Ramondia

What Sweetcorn Ramondia is

Sweetcorn Ramondia (Zea mays) is an annual vegetable of the grass family (Poaceae). Very early bicolour super sweet corn (75% yellow and 25% white kernels).

The slender but long cobs offer crunchy, juicy, very sweet corn of perfect quality.

Ramondia is also suitable for baby corn production.

This is a widely adaptable hybrid variety.

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 Ramondia

Sweetcorn Ramondia seeds are sown in April and 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 Ramondia

• 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

Sweet corn can be grown in a variety of climatic conditions, but it requires high temperatures during the growing season. The plant begins to develop when temperatures rise above 10-12°C for normal sweet corns, while super sweet hybrids need soil temperatures of around 15°C. 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 Ramondia be sown?

The recommended sowing months are April and May. Sowing method: direct.

How many seeds are in the packet?

The packet contains 5–8 seeds, pack size 1 g.

What is the germination rate of the seeds?

The measured germination rate of this batch is 96%. 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.
