Sow at a depth of approx.
1.95 inches (5.0 cm) and aim for a distance of at least
3.9 inches (10.0 cm) between Bean plants. For optimal germination, soil temperature should be a minimum of
16°C / 61°F.
By our calculations, you should look at sowing Roquefort about 14 days after your last frost date.
Roquefort is tender, so ensure you wait until all danger of frost has passed in your area before considering planting outside.
