Grow Sweetcorn ‘Braveheart’ – A New Super Sweet Variety for UK Gardens
Sweetcorn ‘Braveheart’ is an exciting new super sweet (SH2) variety that delivers exceptional sweetness and crisp texture. Offering a sweeter flavour than the popular ‘Incredible’ variety, ‘Braveheart’ matures in approximately 80 days, making it a great choice for UK gardeners. This reliable variety grows well in the UK climate, providing delicious cobs perfect for summer barbecues and fresh, homegrown meals.
Understanding Sweetcorn Types
Sweetcorn varieties are classified by their sweetness and texture. Here’s a quick guide:
- Standard Sugary (su): Traditional varieties with moderate sweetness. The sugars convert to starch quickly, so they’re best eaten fresh after picking.
- Sugar Enhanced (se): Sweeter than standard types, with a creamy texture. They retain their sweetness for longer.
- Super Sweet (SH2): These are the sweetest varieties and keep their high sugar content for the longest. ‘Braveheart’ falls into this category, offering intense sweetness that makes it stand out.
Compared to ‘Incredible,’ which is a sugar-enhanced (SE) variety, ‘Braveheart’ is significantly sweeter while maturing in the same amount of time, making it a fantastic upgrade for gardeners looking for an extra burst of flavour.
Growing Conditions
Sweetcorn grows best in warm, sunny locations with fertile, well-drained soil. In the UK, it’s ideal to start seeds indoors in late April or early May, then transplant them outdoors after the last frost when the soil has warmed to at least 10°C. Planting sweetcorn in blocks rather than rows improves pollination, ensuring fuller cobs. Regular watering and mulching help maintain healthy growth.
Planting Guide
- Sowing Indoors: Sow seeds 2.5 cm deep in individual pots of seed compost in late April. Keep them in a warm, bright location. Once seedlings are 10–15 cm tall and the frost risk has passed, harden them off before planting outside.
- Transplanting Outdoors: Choose a sunny, sheltered spot. Plant seedlings in blocks, spacing them 35–40 cm apart in all directions to improve pollination.
- Direct Sowing: In warmer areas, seeds can be sown directly outdoors in late May. Sow them 2.5 cm deep, spaced as above.
Care & Maintenance
- Watering: Water regularly, especially during flowering and cob formation, to ensure healthy growth. Avoid overhead watering to reduce the risk of disease.
- Feeding: Enrich the soil with well-rotted manure or compost before planting. Feed every two weeks with a balanced liquid fertiliser during the growing season.
- Weeding: Remove weeds to minimise competition for water and nutrients. Mulching helps suppress weeds and retain soil moisture.
Harvesting & Storage
Harvest cobs when the silks turn brown and the kernels release a milky juice when pressed. ‘Braveheart’ is ready to harvest approximately 80 days after planting. For the best flavour, pick cobs just before cooking, as sweetness diminishes after harvest. If needed, store them in the fridge and consume within a few days.
Culinary Uses
Sweetcorn ‘Braveheart’ is perfect for summer dishes. Boil, steam, or grill the cobs, or add the kernels to salads, soups, and salsas. Its super sweet taste makes it a highlight at barbecues, or simply enjoy it with a little butter for a classic treat.
