Sweet Corn Swift F1 Seeds

• Planting in blocks helps pollination.
• Harvest when silks start to turn brown.
• For best flavour and nutrients, eat sweetcorn as soon as possible after picking before the sugar turns to starch. Don’t add salt to the water if boiling as it will toughen the kernels.
• Ideal for freezing.

How to grow Sweetcorn

• Sow indoors, March to May – a warm kitchen windowsill is all you need for starting these seeds. Sow 1.5cm (½in) deep in pots of compost. Keep warm and moist. A temperature of 15-20°C (60-68°F) is ideal. Seedlings appear in 7-21 days. Gradually accustom plants to outside conditions (avoid frosts) before planting out, when frosts are over. Plant in blocks and allow 40cm (16in) both ways between plants, disturbing roots as little as possible.
• Or sow outdoors, in May, 1.5cm (½in) deep, 2 seeds together at 40cm (16in) intervals in block formation. Outdoor sowings may benefit from cloche protection if temperatures drop. Thin to the stronger seedling when large enough to handle.

Harvest:

• April to September, once the silks begin to turn brown.
• Note: Xtra-Tender© corn can be grown with Supersweet corns but isolate from Sugary enhanced types as they will go starchy.

Our experienced nursery team will always send your plants nursery fresh in the perfect condition to thrive when you plant them, so although most plants are very tough and will not be affected by all but the most extreme frosts or heatwaves, we avoid dispatching the most perishable plants if extreme weather is forecast, or over Bank Holiday weekends.
