Start seeds indoors six weeks before last frost date.
Try to aim for a seed spacing of at least 0.78 inches (2.0 cm) and sow at a depth of around 0.39 inches (1.0 cm). For optimal germination, soil temperature should be a minimum of 12°C / 54°F.By our calculations, you should look at sowing Bisignano about 42 days before your last frost date.
Plant to the first set of true leaves to promote strong root growth.
Bisignano is tender, so ensure you wait until all danger of frost has passed in your area before considering planting outside.
