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 Chalk's Early Jewel about 42 days before your last frost date.
Plant to the first set of true leaves to promote strong root growth.
Ensure that temperatures are mild and all chance of frost has passed before planting out, as Chalk's Early Jewel is a tender plant.Reportedly developed out of Tomato ‘Bonny Best’ in 1899 and introduced to the market in 1910 by James Chalk of Norristown, Pennsylvania, USA.
