Sow at a depth of approx.
1.95 inches (5.0 cm) and aim for a distance of at least
11.7 inches (30.0 cm) between Dent corn plants. Soil temperature should be kept higher than
18°C / 64°F to ensure good germination.
By our calculations, you should look at sowing Blue Dent about 10 days after your last frost date.
As Blue Dent is tender, ensure temperatures are mild enough to plant out - wait until after your last frost date to be on the safe side.
