Try to aim for a seed spacing of at least
11.7 inches (30.0 cm) and sow at a depth of around
1.17 inches (3.0 cm). Soil temperature should be kept higher than
21°C / 70°F to ensure good germination.
By our calculations, you should look at sowing Mirai 002 about 14 days after your last frost date.
As Mirai 002 is tender, ensure temperatures are mild enough to plant out - wait until after your last frost date to be on the safe side.
