Start seeds indoors six weeks before last frost date.
Sow at a depth of approx. 0.78 inches (2.0 cm) and aim for a distance of at least 2.60 feet (80.0 cm) between Tomato plants. Soil temperature should be kept higher than 12°C / 54°F to ensure good germination.By our calculations, you should look at sowing San Francisco Fog about 42 days before your last frost date.
Transplant out when around 15cm (6 inches) high.
Plant to the first set of true leaves to promote strong root growth.
As San Francisco Fog is tender, ensure temperatures are mild enough to plant out - wait until after your last frost date to be on the safe side.
