Aim to sow
0.23 inches (0.6 cm) deep and try to ensure a gap of at least
3.9 inches (10.0 cm). Soil temperature should be kept higher than
13°C / 55°F to ensure good germination.
By our calculations, you should look at sowing Tokyo Long White-Bunching about 28 days before your last frost date.
As Tokyo Long White-Bunching is very hardy, ensure temperatures are mild enough to plant out - wait until after your last frost date to be on the safe side.
