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 Dawson's Russian Oxheart about 42 days before your last frost date.
Plant to the first set of true leaves to promote strong root growth.
As Dawson's Russian Oxheart is tender, ensure temperatures are mild enough to plant out - wait until after your last frost date to be on the safe side.Developed by Jeff Dawson of Napa, California, USA, from a cross of Russian 117 and Georgia Streak. 1 It was first offered in the early 2000s by the SSE catalogue, then first introduced commercially in 2009.
