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 Four-Way about 60 days before your last frost date.
Ensure that temperatures are mild and all chance of frost has passed before planting out, as Four-Way is a tender plant.
