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 0.78 inches (2.0 cm). Soil temperature should be kept higher than 12°C / 54°F to ensure good germination.By our calculations, you should look at sowing Green Giant about 42 days before your last frost date.
Plant to the first set of true leaves to promote strong root growth.
As Green Giant is tender, ensure temperatures are mild enough to plant out - wait until after your last frost date to be on the safe side.From Reinhard Kraft in Germany. Kraft selected the tomato from an unknown regular-leafed green variety (he indicated he didn’t know the parent’s name, but believed the original seed came from Canada). The variety was grown out and stabilized.
