Sweet Corn Mirai Picnic F1 RHS Seeds.

 

Sweet Corn Mirai Picnic F1 (Zea mays L.) is a premium supersweet hybrid recognised with the RHS Award of Garden Merit for its exceptional eating quality and reliable performance.

 

This outstanding variety produces medium-sized cobs packed with plump, golden-yellow kernels that are juicy, tender, and remarkably sweet perfect for eating straight from the cob, grilling, or adding to summer dishes.

 

Unlike traditional sweetcorn, Mirai Picnic F1 offers improved sweetness and a crisp bite, making it a real treat for home gardeners and food lovers alike. Plants are strong and uniform, maturing early, and performing well even in cooler UK and Irish growing conditions. Its compact growth habit makes it especially suitable for smaller gardens or those looking for reliable results in shorter growing seasons.

Sowing Instructions

 

Indoors: Sow in April in deep pots or modules with fine seed compost, placing one seed 2–3 cm deep per pot. Keep at 18–21°C and maintain consistent moisture. Harden off young plants before transplanting outdoors after the last frost.

 

Outdoors: Direct sow from mid-May once soil has warmed. Plant 2–3 cm deep, spacing 40 cm apart in blocks (not rows) for good wind pollination. Water well and mulch to retain soil moisture.

 

Growing Tips: Plant in a sunny, sheltered site. Water generously during dry spells and feed with a high-potash fertiliser as cobs develop to ensure the sweetest, fullest harvest.

 

Harvesting: Pick cobs when tassels turn brown and kernels release a milky juice when pressed. Cook and enjoy immediately for the best flavour and sweetness.

 

Sweet Corn Mirai Picnic F1 is perfect for gardeners who want a high-quality, reliable, and early sweetcorn variety with unbeatable taste – an RHS-approved choice for summer harvests.
