Growing Sweetcorn Seeds: Questions & Answers
(Updated 02/03/2025)
When is the best time to plant sweet corn seeds?
Sweet corn seeds should be planted in late spring when soil temperatures reach at least 15°C, ideally between 18-24°C for good germination.
Cold soil can delay sprouting and lead to poor growth. In warmer climates, a second crop can be planted in midsummer for a late-season harvest. Avoid planting too early, as frost can damage young seedlings.
How do I plant sweet corn seeds?
Sow sweet corn seeds directly into well-prepared soil about 2.5-5 cm deep and 20-30 cm apart.
How deep do corn roots grow
Plant in blocks of at least four rows (rather than a single long row) to ensure good wind pollination. Water the soil well after planting, and keep it consistently moist during germination, which usually takes 7-10 days. Thin weaker seedlings if necessary to maintain strong growth.
What type of soil is best for growing sweet corn?
Sweet corn thrives in well-draining, nutrient-rich soil with a pH between 6.0 and 6.8.
