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). For optimal germination, soil temperature should be a minimum of
20°C / 68°F.
By our calculations, you should look at sowing Golden Summit about 60 days before your last frost date.
Golden Summit is tender, so ensure you wait until all danger of frost has passed in your area before considering planting outside.
