A reliable performer in British summers, Sweetcorn Northern Extra Sweet is especially suited to cooler northern districts. One of the earliest maturing of the 'supersweets', Sweetcorn Northern Extra Sweet produces good quality, well filled cobs up to 20cm (8in) long. Sturdy plants but growing only to 150 to 180cm (5 to 6 feet) tall.
Gradually acclimatise to outdoor conditions for a few days before planting out after all risk of frost.
Keep well watered, and mulch during dry periods.
