Try to aim for a seed spacing of at least
0.98 inches (2.5 cm) and sow at a depth of around
0.25 inches (0.64 cm). Soil temperature should be kept higher than
20°C / 68°F to ensure good germination.
By our calculations, you should look at sowing Chocolate about 32 days before your last frost date.
As Chocolate is tender, ensure temperatures are mild enough to plant out - wait until after your last frost date to be on the safe side.
