Sow 3–6 mm deep in soil at 16–29 °C
Start seed indoors 6–8 weeks before the last frost. Cover it with 3–6 mm of seed-starting mix and keep the soil at 16–29 °C. At 20–30 °C seedlings usually appear in 6–8 days (figure measured with seed sown about 12 mm deep). These are typical values for tomatoes as a species, not a test of this packet.
Planting out and support
Move plants outside after the last frost. Space them 60–90 cm apart in well-drained soil at pH 6.0–6.8 and at least 6–8 hours of direct sun. As an indeterminate variety it keeps growing and fruiting all season, so set a stake or cage at planting. The first ripe fruit comes about 70–80 days after transplanting, counted from planting out rather than from sowing.
